No single factor is of greater importance m dealing with the health of nations. Although almost every modern school and institution recognizes this fact and makes some sort o f attempt to evaluate the physical condition o f its charges, too often the examinations made are either valueless or actually uetrimental in effect, owing to faulty methods or improper appli cation. It is becoming of daily increasing importance that practical and uniform standards for making these examinations be de veloped for the everyday use o f the great mass o f workers An enormous amount o f research in this field is being carried on by vanous agencies and independent investigators, with very - results* 11 has l°ng been obvious to many o f these workers that their progress would be very markedly advanced if some means could be found o f coordinating all these various pieces o f work, l.very student o f the literature on any scientific subject is impressed by the waste and delay involved in duplication and overlapping o f research where the whole field is so inadequately covered. Variations in metho.ds o f work or m instruments used, and failure to take full advantage o f the previous findings o f others also contribute to this With the idea o f promoting cooperation among the students of the problem o f physical fitness the Children’s Bureau called a conference o f leading experts m this and related fields which met at the bureau* on October 11, 1922. The members o f the conference were as fol•. P* B.

C. ; Harriet Wedgwood, American Child Health Associa tion, New York City; and Dr. Jesse Feiring Williams, Columbia University, New York City, The conference was attended by the following members o f the Children’s Bureau staff: Grace Abbott, Chief o f the Children’s Bureau; Dr. Ella Oppenheimer, director, and Dr. Edith E. Nicholls, o f the child-hygiene division; Dr. Anna E. Rude, director, and Dr. Ethel M. Watters, associate director, o f the maternity and infant-hygiene division ; and Dr. Robert Morse W ood bury, director of the statistical division of the bureau. The conference discussed plans for systematizing and corre lating the numerous investigations which had already been made and for initiating researches needed to round out the study o f the problems of physical fitness. As a result of the recommendations of the conference several important investigations and studies were undertaken by the Children’s Bureau, including studies of rickets in Washington, D. C., and in New Haven, Conn., and a posture demonstration among school children in Chelsea, Mass.1 The conference considered that one of the first steps to be taken was a thorough review o f all the work that has been done along these lines in the past. Approximately 10,000 books and articles dealing with the various phases of physical fitness in children have been examined with care, and much has been found to be o f little or no value. This bibliography, therefore, does not include all this material, but it indicates the contents o f about 2,500 articles in such a way that future investigators can find for themselves with the least possible delay whatever material in the work of their prede cessors will be of assistance to them. In general, only articles reporting original research have been annotated. The articles in cluded were those available up to July 1, 1926. In the section on growth in weight and height one is impressed by the necessity for uniform and better standards of measurement which this compilation brings out. Immense effort has been devoted to these studies, but owing to faulty methods of one kind or another large proportion of the work is almost valueless. The need for consideration o f standards in the problems o f physical fitness is obvious. This bibliography should be an aid in the promotion of this end. The bibliography was planned by Dr. Ella Oppenheimer, director o f the child-hygiene division of the bureau ; the reading of the litera ture was done by the following members of the bureau staff: Dr, Isabel Perry, Dr. Edith Nichols, Mrs. Helen Pope, Evangeline Ken dall, Anna Kalet, and Dora Hansen ; the medical editing by Dr. Kate Karpeles ; and the classification and arrangement by Doctor Karpeles and Helen W. Ford. 1 In connection with the posture demonstration reports have been issued on Posture Clinics and Posture Exercises (U. S. Children’s Bureau Publications Nos. 164 and 165, Washington. 1926). https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis CONTENTS Foreword.. ____________________ Section I.

Account of 4,145 measurements of 1,462 school boys, aged 8 to 23 years to ascertain effect of school on physical development. Height, chest circiim ference, weight, lung capacity, and muscular force were obtained, usually at the beginning and end of the academic year. Most of the boys were measured two or more times. Findings are discussed and compared with those of other writers. Several tables and diagrams are presented. A llaria, G. B. : “ Ricerche antropometriche sulla crescenza delle fanciulle povere” [Anthropometrical studies of the growth of poor girls] II Ramazzini [Florence], vol. 6 (1912),. pp. 60-86. The author studied 652 girls employed in urban industrial establishments 420 m cotton factories in a rural district, and 158 girls of well-to-do families’ Their ages varied from 12 to 21 years. He gives for each of these groups and for each year of age the height, weight, lung capacity, hemoglobin content -of the blood, muscular force, longitudinal and transversal diameters of the skull cephalic index, and bisacromial diameter. All these measurements were higher for the well-to-do girls than for the poor girls. This superior physical de velopment of the well to do the author attributes to their more favorable social and domestic environment and the fact that they are free from the bad conditions of industrial work. 1 https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 2 PHYSICAL GROWTH AND DEVELOPMENT OF TH E CHILD 8 A llix , É m ile: Étude sur la physiologie de la première enfance [A Study of the Physiology of Early Childhood].

A study, continued for six years at Amherst College, of the physical measure ments of 1,258 students of average development and 57 college athletes, to show the difference, if any, between the athlete and the average man. Each examination included a^out 35 body measurements and several tests of strength. The athletes exceeded the average by 6.92 per cent in weight and 10.24 per cent in tests of strength. In other measurements the differences were small. 1 1 -----------, Physical Education Department : “ On some relations of human stature to muscular strength.” Publications of the American Statisti cal Association [Boston], yol. 3 (189 2-93), pp. 347-349.

(Reviewed in Zentralblatt für die Gesamte Kinderheilkunde [Berlin], vol. 19 (1926) , p. 278.) The author studied the physiological loss of weight and the course of the weight curve of 493 newborn infant?. About 6 to 7 per cent reached their original weight within the first eight days, 50 per cent within the first two weeks, and 75 per cent within the first three weeks. In 25 per cent of cases the increase in weight was abrupt, in 75 per cent slow and gradual.' First born children regained their original weight more slowly than second born. Children who were underweight at birth regained their original weight sooner than those horn with a normal weight. A ppleton, V . B . : “ Growth of Chinese.” Am. J. Dis. Child. [Chicago], vol. 30 (1925), pp, 48-49. Two hundred and twenty-four girls, aged from 6 to 22 years, students in two cities in Chekiang Province, East China, were measured, and examined for physical traits related to growth and development. All measurements were made by the author, with anthropometer and calipers. Age was accurately determined. Tables give average for age, for groups of from 5 to 34 subjects, of 12 absolute measurements, and o f 10 computed relative measurements. The brain of a Chinese girl continues to grow after adolescence. Annual increase in height is accelerated from the tenth to the thirteenth year ; growth in stature continues until the eighteenth year. Annual increase in weight is greatest from 9 to 16 years. Adolescence was found to be not as much delayed in Chinese as is frequently assumed. References. ------ — “ Further study of the growth of Chinese,” China Medical Jour nal [Shanghai], vol. 40 (1926), pp. 259-264. One of a series of studies made by the author to discover factors which govern the growth of Chinese Children and to determine which variations are due to innate racial growth impulse and which to accidental accessory causes, such as climate and hygienic condition. The material for analysis consists of a series of wèight-height-age measurements made on 345 male students in Fukien, from 9 to 24 years of age, and a similar series made on 242 Chinese boys in Hawaii. The Chinese in Hawaii were superior in height, weight, and rate o f growth. The author notes that dental caries is more prevalent among Chinese children in Hawaii than among those in China.

To test the theory that school progress of children is •determined in large measure by their weight the author weighed the children in four schools in New York City successively for a number of terms. Technique and number of observations are not given. Analysis of the results, in the author’s opinion, confirmed the theory that the heavier the child for his age the higher will be his school grade. 21 A ron : “ Über Körperbau und Wachstum von Stadt- und Landkindern ” [Build and growth of city and .country children].

Aron and Lubinsky measured height and weight of 223 school boys of the village of Deutsch-Rosselwitz, 202 from private schools in Breslau, and 261 from city public schools. All were of the same race. Ages wére 7 to 13. Results are put in tables. The private-school pupils showed greatest height and weight. The country children showed lowest height and weight, but little above^that of city public-school children. However, for Livi’s index ponderalis. 100 wt, ^he country children showed the best results and the private-school lit pupils the worst. Thus thé work of the country children seems, to retard height and develop muscles. The superior height of the city children i? but a temporary phenomenon ; other children later equal them. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GENERAL GROWTH IN W EIGH T AND H EIG H T 5 22 Aschenheim , E rich: “ Ergebnisse von Schuluntersuchungen in Rem scheid ” [Results of examinations of school children in the city of Rem scheid].

Washington. 212 pp. An important investigation based on consecutive measurements, at yearly and half-yearly intervals for periods of 3 to 12 years, of 861 boys and 1,063 girls in elementary schools of high standing in Chicago and New York. A total of 33,840 measurements of height, weight, and lung capacity were taken by trained anthropologists, and measurements were recorded in age groups within three months of the exact age of the child. A detailed study was made of records of health and school progress, and 34 tables and 39 charts were constructed showing results of the investigation. The general conclusion is drawn that the tall, heavy boys and girls with good lung capacity are older physiologically and more mature mentally than short, light hoys and girls.

The author, after referring to his former studies on this subject, urges use of the individualizing method. From data on about 2,500 normal boys and girls under physical training he gives growth curves in height for boys and girls and points out that on account of the evenness of growth predictions in respect to this can be made by the Pearson method or the regression formula. From 143 boys and girls examined at the Iowa Child Welfare Research Station by the Stanford revision of the Binet scale, of whom 42 had had four school examinations and 36 had had five, the author makes mean mental growth curves of average and of superior boys and of girls up to 14 years. He next gives the intelligence-quotient curves of superior and average boys and girls. Finally he repeats an earlier statement that tall, heavy children are more mature 'physiologically and mentally than short, light children. —-------- L. W . Campbell, and H . J.

Measurements of school boys contain an element of uncertainty because of the difficulty of determining exact age, but on the whole show a growth curve lower than that of Mexican and Italian children; since the adults of Sicily and of Porto Rico have approxi mately the same stature, a retardation in growth of Porto Rican boys seems to be indicated. Eruption of permanent teeth, however,- seems to be about one year in advance of normal. The cephalic index shows Porto Rican boys to be roundheaded.

Statistics gathered in 1891 and 1892 in the schools of Worcester, Mass. Full particulars will be found in the Report of the Commissioner, United States Bureau of Education, 1904, pp. 47-132. The author derives tables showing the average increase in stature in boys and girls in one-year periods from 5 to 16; also a table showing comparative rate of growth of short and tall children, in one-year periods, from 6 to 16. He concludes that young children grow more uniformly than older children; that short children are retarded in development throughout growth, but are likely to make this good by. longer adolescence. From examination of the figures of Bowditch as to Boston children of differing nationalities, he concludes that differences in development in varying social classes are largely results of acceleration and retardation of growth and tend to disappear during the last years of growth. 80 ---------- “ The growth of first-born children.” Science [New York], new ser. vol. 1 (1895), pp. 402-104.

Data consist of measurements of several thousand school children, in Worcester, Mass., in 1891 and 1892. Weights with clothing, without shoes, are given in pounds ; all measures of length are in millimeters. Stature measured standing free, by rod with sliding arm ; height, sitting on a level seat, whenever possible knees above level of seat. Head measurements taken with pointed calipers. Breadth of hand, from first to fourth finger across knuckles, hand flat. Pages 47—132 give graphic and tabulated summaries of these measurements. The authors conclude that peculiarities of growth are due to varying rapidity of development and that this variability conforms with the general variability in the rapidity of physiological development as deduced from observations on gestation, dentition, puberty, senility, and mental achievement. From these data and conclusions there is deduced a new table of growth giving the typical— not average—statures for each age. Bobbitt, J.

Heights werè taken without shoes; weights with clothing, and allowance for clothing estimated; birthplace of subjects, nationality and occupation of parents, and color (white, black, or mulatto) were noted. Average heights and weights for different ages and nationalities were calculated. The author found : (1) Boys are heavier and taller than girls to age 11, when for two or three years this condition is reversed ; (2) children of American-born parents are taller and heavier than those of foreign-born parents; (3) pupils in selected (private) schools are superior in height and weight to public-school children and to English boys of nonlaboring classes; (4)- below 58 inches boys are heavier than girls in pro portion to height ; above 58- inches the reverse is the case.

Boston in 12 tables giving heights and weights of boys and girls of all nationalities, from 5 to 18 I years, in inches and centimeters, and in pounds and kilograms, with 11 per centile grades from 5 per cent to 95 per cent and averages. He rearranges the same material in curves, adding a comparison of the percentile rank of -Italian children based on observations of Pagliani, and of Russian factory children, based on observations of Emilmann, with Boston children. Hé concludes that maximum yearly growth is greater in boys than girls but occurs two or three years later in boys ; that large children make their most rapid growth earlier than small ones ; that the period of accelerated growth in large boys differs from that in small boys rather in duration than in intensity ; that the retardedgrowth period occurs in boys at about 11 years and in girls at about 9 ; and that during the period of female superiority height is more marked in the lower and weight in the higher percentile grades. He comments on the fact that children of American parentage in the public schools, are-usually larger than those of other nationalities.

To investigate the growth of limbs of human beings and other mammals the author measured whole limbs and parts of limbs of the fetus, comparing results with measurements of the adult made by Professor Alby. Sex was noted, and data arranged according to size, not age. For human beings nine tables are given showing absolute length of limbs, relative length in per centages of body length, dimensions of parts of hand and foot in percentages of body length, length of upper limbs as compared with lower, relative length of fingers, etc., and the conclusions are drawn that hand and foot grow more rapidly than arm and leg before birth and less rapidly after birth; that the micfdle finger and big toe are relatively longer before birth than after ; that in the early fetus the upper and lower limbs are the same length, but the lower limbs become longer with development ; that the thumb grows rela tively shorter ; that there is an interesting variation between ring finger and forefinger. He concludes that the law of growth for the extremities of human beings and other mammals is probably the same but that further study should be made before definite conclusions can be formulated.

From other students’ statistics and a few personal observations the author gives two tables, one on increase in weight and one on increase in height of boys and girls separately, from 1 to 18 years of age. He enumerates various phenomena of absolute and relative growth, such as regular fluctuations in weight and height during the day and the year, the periods of accelerated growth the effects of sex, occupation, and material prosperity. e https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 18 121 122 123 124 125 126 PHYSICAL GROWTH AND DEVELOPMENT ÔE TH E CHILD Camerer, W ., J r .: “ Gewichts- und Längenwachstum der Kinder ” [Children’s growth in weight and height]. Pfaundler und Schloss mann : Handbuch der Kinderheilkunde, vol. 1, pp. 232-247. Leipzig, 1910. The author notes variations in length and weight due to time of day and year, state of nutrition, and time spent in bed and discusses the advantages and disadvantages of the generalizing and individualizing methods in statistics. He describes the general laws of growth, first in weight and then in height, and discusses initial loss of weight after birth, the difference produced by natural and artificial feeding, the long-continued effect of low weight at birth, the superiority in weight of boys over girls exeept when the earlier puberty of girls gives them the advantage, and the cessation of physiological growth at 16 for girls and 19 for boys. The length of boys at birth he puts at 49 centimeters and of girls at 48 centimeters. He calls attention to the periods of most rapid growth— the first year of life and puberty. Pubertal growth in length begins at 12 in girls and 13 in boys. Three tables give weights of breast-fed and artifi cially-fed infants and weights and lengths of children from 1 to 18 years of age. The figures are based chiefly on the elder Camerer s observations. Many details of growth are illustrated in 13 graphs. -— “ Gewichts- und Längenwachstum der Kinder, insbesondere sol cher im ersten Lebensjahre” [Growth in weight and height of chil dren, especially up to 1 year of age].

Data were obtained by the systema tic weighing and measuring of boys'in the military schools at Montreuil and Saint-Hippolyte at six-month intervals in the years 1886 to 1890— a total of 10,497 observations. Weights and measure ments were taken without clothing. Results are tabulated to show arith metical average of height, weight, and chest circumference, ages 13 to 18, prog ress of growth, and relationships between the measures taken. Extended discussion of the influence of puberty, race,, sex, surroundings, and school training, climate, seasons, and sickness is given.

This principal of a Breslau school containing 600 boys from 6 to 16 vears old measured their height without shoes on the 1st o f April, July, October and January of two years. The resulting 4,274 measurements he put into’ two tables according to age, one of heights and annual and semiannual growth in height and the other of maximum and minimum heights, with the difference between them. The annual increase in height was about 4.8 centimeters to the age of 12, after which it kept increasing to 7.5 at 15. Variations in height at a given age increase to age of 15. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GENERAL GROWTH IN W EIGH T AND H EIG H T 127 19 Cassel, J., and H .

Eight tables present actual weights and heights of such children. Averages calculated from this material, and the Riedel and Skibinsky figures for normal children, are put into tables, interpreted through the Pirquet-Index and Livi-Index, represented by diagrams and variation polygons. The author found that rachitic children evidence practically no inferiority in height and very little in weight. Even this inferiority the author believes due not to rickets but to other ill effects of the same factors that caused the rickets. Christopher, W .

Klinische Wochenschrift [Berlin and Munich], vol. 1, pt. 2 (1922), pp. 2051-2052. For the purpose of determining the differences in the weight of legitimate and illegitimate newborn infants the author studied the weight at birth of 1,982 infants born alive in the city hospital of Frankfurt on the Main. In three tables he presents the weights according to legitimacy, order of birth, and sex. There was practically no difference between the legitimate and illegitimate first-born children; legitimate second-born children were heavier than illegitimate; this, in the author’s opinion, was due to general social con ditions and to the mother’ s environment. The prevailing viewpoint that illegitimate children are. generally lighter in weight than those of legitimate birth is attributed by the author to the fact that first-born are most frequent among them. 145 Combe, A . : “ Korperlange und Wacbstum der Volksschulkinder in Lau sanne ” [Height and growth of public-school children in Lausanne].

Data for this paper were taken from records made by the writer or under his immediate supervision of New York City high-school boys during the years 1901 to 1906. All tables are based upon a large number of observations, often in the thousands. On this evidence the writer believes that all observations of the adolescent— anthropological, medical, educational, or social— must hereafter rest upon classification as prepubescent or postpubescent and not upon chrono logical age. Following careful definition of the terms involved he constructs curves showing the expectancy of pubescence and degree of postpubescence for half-year groups from 12% to 18% years of a ge; derives an empirical per centage for each half year and compares with it the values for children of German and American parentage derived from records of about 600 highschool children. Correlating weight, height, strength, and scholarship with pubescence, he finds postpubescents differing from prepubescents, both mentally and physically. He finds that growth rates are dependent upon pubescent periods and not upon age; that accelerations in weight, height, and strength occur at the same tim e; and that the more rapid the development the more rapid is the gain in weight, height, and strength. Concluding with a discussion of the significant features of life centering about puberty, he adds as appendixes an analysis of the racial constitution of the group studied; an investigation of elementary-school boys as to correlation between eruption of the teeth, and weight and height; a chart of various physiological epochs, founded upon Boas, and a table of preliminary observations as to correlation of weight, height, and first menstruation. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 22 149 150 151 152 153 154 155 156 PHYSICAL GROWTH AND DEVELOPMENT OP TH E CHILD Crum, Frederick S .: “Anthropometric statistics of children— ages six to forty-eight months.” Publications of the American Statistical Asso ciation, 1916-17 [Boston], new ser. vol. 15, no. 115 (1918), pp. 332336.

In various parts of India 1,849 infants were weighed by medical women, and for purposes of comparison weights at birth of 289 normal infants born in India of other than Indian parents were also collected. Results show that the average weight of Indian infants (6.5 pounds) compared favorably with that of infants o f other parentage; that there is no appreciable difference in birth weight of Mussulmans, Hindus, and Indian Christians; that the early marriage age has no adverse effect on birth weight; that high mortality must be due largely to postnatal conditions.

To anthropometric material collected by many investigators he has added measure ments made by himself and two assistants on boys and girls of all ages from 3 to 17, inmates of the Orphan Asylum of Brooklyn. The racial stock he describes as predominantly “ Nordic.” Fourteen growth curves and seven basal tables of stature and weight derived from this mass of material support the theory of discontinuous growth.

From an examination of other authors’ material and a long table compiled for him of weights taken about every week of a very healthy breast-fed boy from his fourteenth week to the seventieth, the author decides that dentition, even when it progresses normally, as in this case, affects the vegetative de velopment of an infant’s body ; the coming of almost every tooth causes a loss of weight. Only the third and fourth incibors and last canine tooth were cut by the infant without a fluctuation in weight.

The author gives for each year of age the average, minimum, and maximum height by sex and by race, for Jews and Russians. He found that the average height of the Jewish girls at 8 and 9 years of age was below that of the boys of those ages; at age 10 it was superior, and at age 14 again inferior. Russian girls of this district at ages 8 to 15 were taller than boys of the same ages. A table of heights correlated with social condition of the parents shows that the children of well-situated parents were taller than those of parents in poorer social condi tion. Heights of Jewish children as obtained by him in 1922-23 were inferior to corresponding heights obtained in 1916. 183 Ekkert, A .

Both individual and collective methods were used. Tables show age of parents at time of children’s birth and height in inches of boys and girls at 6 years of age ; best age combinations for father and mother ; age of mother and physical development of child at birth ; in fluence of social status on the age curve of physical development at end of sixth year ; relationships of intervals of birth and physical development. The author finds some correlation between height and intellectual development in well-to-do classes. In general, he concludes that the physical and mental development and the vitality of the progeny vary with the age curve as related to fecundity of the parents, the best girls being produced shortly before the summit is reached and the best boys a year or two later. 198 ----------- “ The influence of the age of the parent at birth of child on eye color, stature, and intelligence.” Journal of H ygiene [Cambridge], vol. 16 (1 91 7-18), pp. 12-35.

Fleischner, E. C. : “ The relation of weight to the measurements of chil dren during the first year.” Arch. Pediat. [New York], vol. 23 (1906), pp. 739-760. Author seeks to determine the relation which weight and measurements of malnourished infants bear to normal weight and measurements and to each other and the degree to which increase in weight influences increase in measurements. Five hundred children arbitrarily classified as well nourished (25 per cent), fairly well nourished (35 per cent), poorly nourished (40 per cent), all under 1 year old and patients in New York hospitals, were measured (method not given) ; data were obtained as to weight, length, circumference of head, chest, and abdomen. Charts and tables summarize these measure ments. Conclusion is reached that increase of measurements of malnourished children shows some variation from normal, and that during the first year the primary factor in increase of body measurements is steady increase in weight.

A discussion of weight and height of 40,290 school children of Berlin from 6% to 16% years old, boys and girls in nearly equal numbers, obtained in 1923 under the auspices of the public-health authorities of Berlin, and comparison with similar data obtained in 1902-1903. The author gives in several tables the height and weight of these children by sex and for every year of age, also the percentage of the decrease or increase between the two above periods by sex and for each year of age. The tables are arranged separately for the publicschool children and for high-school pupils who usually belong to the more com fortably situated middle class. The results show that the high-school pupils were taller and heavier than the public-school children of the same ages ; but in 1923 the difference in their favor was much smaller than before the war which shows that the middle classes suffered more from the bad economic conditions due to the war than the working classes. 221 Freund, W . : “ Zur Pathologie des Längenwachstums bei Säuglingen und über das Wachstum debiler Kinder ” [On the pathology of infants’ growth in length and on the growth of delicate children].

New York, 1924. 36 pp. The three major subjects of this report are: (1) The stature and weight of Italian children in New York City as compared with other racial groups; (2) the dentition of Italian children; (3) the seasonal variation in growth of Italian children in New York City. Average statures were obtained from measure. ments o f 1,608 hoys and 1,899 girls, aged 1% to 13% years, brought to the clinic of the Mulberry Health Center for physical examination; average weights, from 1,753 boys and 2,030 girls, aged 1% to 14% years, from the same group. Weights were taken with indoor clothing, heights with shoes. Measurements were recorded to the nearest- pounds and inches. Age was reckoned to the last birthday. Records of dentition were secured by the supervising school dentist and recorded in the case of 1,150 boys and 1,200 girls between 4 and 13 years of age. Records of successive weight-were available for 363 boys and 614 girls under the supervision of the nutrition workers. The average period of observa tion for girls was 4.15 months; for boys, 3.8 months. Charts and tables show comparison of these results with the Woodbury and Burk-Boas norms of growth, with the growth of southern children, and with the growth of “ Latin ” children in Detroit public schools; also of the seasonal variation in growth with that of Boston school children. 237 Geissler, A rth u r; “ Messungen von Schulkindern in Gohlis-Leipzig ” [Measurements of school children in Gohlis-Leipzig].

Geissler discusses measurements of height and weight made by Hasse at the end of the summer vacation in 1889 on 1,386 boys and 1,420 girls from 6 to 14 years old attending the schools of Gohlis-Leipzig. Measurements were takgn without shoes and upper garments. Average results are shown in a table. By using special weight-height indexes, which he explains, for the two age groups, 6 to 11 and 11 to 14, the author found that these children were well developed as compared with those measured by Erismann, Pagliani, Landsberger, Carstadt, Geissler, and Uhlitzsch, and even by Kotelmann and Bowditch. Better develop ment was found among well-to-do than among poor children. 238 -----------and Bichard U h litzsch : “ Die Grössenverhältnisse der Schulkin der im Schulinspektionsbezirk Freiberg” [Height relations of school children in the school district of Freiberg].

The authors compare their figures with those of Quetelet for Belgium, Bowditch for Boston, and Erismann for Central Russia, and with the official statistics for the Kingdom of Saxony. They conclude: The children of the school district of Freiberg are below the normal height of Saxon children; the boys are superior to the girls in height, except from the eleventh to the six teenth year; the children of the mining class are inferior in height to those of the burgher class. 289 Gihon, A.- L .: “ Report based upon the examination of 6,129 candidates for admission to, and pupils in, the Naval Academy,” in “ Report of the Surgeon General of the United States Navy for the year 1879.” Report of the Secretary of the Navy, pp. 183-205.

Archives de médecine et de pharmacie militaires [Paris], vol. 36 (1900), pp. 117-121. To discover, if possiblè, a definite standard of height for admission to military schools the author examined the records o f 1,000 cadets at Saint-Hippolyte, finding none of 130 centimeters and under at 13 years and few of 132 centi meters, who reached 154 centimeters at 18 years. Studying at Andelys a series of 400 of 130 and 132 centimeters he found his results confirmed. By further researches, his own and others, he estimated the average growth in stature from 13 to 18 years as 20 centimeters, making the required stature at 13 years 134 centimeters.

Bulletins et mémoires de la Société d’anthropologie de Paris, ser. 5, vol. 10 (1909), pp. 497-501. From measurements of 100 adults (details not given in this article) the author constructed a table showing» the average which an adolescent must reach, in 6 anthropometric values, to become adult. From measurements of a number of adolescents he determined the average of adolescent growth and the growth to be made between the adolescent age and full maturity. Esti mating the rate of postadolescent growth, he concludes that puberty commences at 15% and ends at 17% and that three more years are necessary for the attain ment of full physiological maturity, ------- — “ Difference de Dévolution de la croissance chez le garçon et chez la fille” [Difference in the evolution of growth between (he boy and the girl].

To illustrate the value of anthropometry in physical education the author gives in detail the results of the semiannual measurements of 200 boys at a military school, ages 14% to 18 years. From these boys he selected two groups of 50 each—-one group composed of those who had regular gymnastic training with apparatus, the other of those who did not. Ten measures of each boy were taken at each half-year period, the results showing the value of the gymnastic training in increased growth and more perfect growth rhythm. Two other groups were also measured, including 14 boys of subnormal nhvsical devrlonment, of whom 7 were given regular gymnastic training. Careful measurements proved the value of the physical training. ----------- “ Formule individuelle de croissance physique pour les enfants des deux sexes” [A formula of individual physical growth for children» o f the two sexes].

(3) Law of proportion ; in the body o f the human being, from the newborn infant to mature man, every part has a certain proportionate relation to the whole. This proportion changes at the end of the sixth year, then at the end of the fifteenth year, and again at the time of maturity. (4) The law of asymmetry, which is found in the organs that come in pairs, for instance, legs,-arms, shoulders. In the right-handed persons the right upper limb is longer and thicker than the left ; the right shoulder lower ; the left lower limb is longer and larger than the right. In left-handed persons the reverse is true.

In a children’s infirmary at Buch in 1920 the author observed many under nourished children, 1 to 14 years old, from the proletariat of Berlin. The children were weighed in their shirts before breakfast and measured after their siesta. Their nutrition was not estimated according to fat pad or the indices of Rohrer, Pirquet, and others. The small children 2 to 6 years old had suffered much from rachitis and fell far below Camerer’s normal figures ; those from 6 to 14 years old, 271 boys and 241 girls, also fell below Rietz’s figures. The diet and general treatment of the children are described. Eightynine per cent were subnormal in weight, 50 per cent in height. Under treat ment the weight increased rapidly until almost normal, and then came an increase in height. The article contains seven curves and six tables. Gray, F.

A survey to determine what factors caused the persistence of malnutrition. Children served by the Friends’ Relief Mission were classified into four nutritional groups : O, normal ; A, fair ; B. had ; C, worst. Three thousand of the C class were studied, with 300 A children for comparison. Investiga tions were made by a trained social worker, with schedule for collection of information. (Sample given.) Methods of weighing and measuring are not given. Tables were compiled comparing average weights in kilos of children 6 months to 6 years old in A and C classes, with normal standard, taken from the Tirquet Clinique, and with weights in kilos of C class children, arranged with reference to the presence of rickets, tuberculosis, or other disease. Size of family and position in family, parental care, cleanliness, air space per person, and family income were considered, and a table was compiled giving the average duration of breast feeding. The author concludes that the three factors determining continuance of malnutrition are illness, size of the family, and position of the child in the famity. Griffith, J. P. Crozer, and. J. Claxton G ittin gs: “ The weight of breast fed infants during the first two weeks of life.” Arch. Pediat. [New York], vol. 24, no. 5 (1907), pp. 321-345. In the Preston Retreat of Philadelphia for confinement of married working women the authors studied the weight during the first two weeks of life of 11 boys and 115 girls, all normal and Tull term. The greatest weights were found in boys whose mothers were between 25 and 29 years, multiparae, and robust. The initial loss is greatest on third or fourth day and is regained by the tenth to the fourteenth day. The heaviest infants lose most, girls begin to regain sooner. The loss is most marked in first-horn children. Grover, Joseph. T. : “ Some measurements of normal children, especially of the leg and arm.

Methods of measurement are given. Many relationships between various measurements are discussed. The author concludes that comparisons of the circumferences of the head and chest are much more accurate in relation to weight than to age ; that the arms and legs grow in a definite relation to the increase in height; that age is a poorer basis for the comparison of any dimensions than is weight or height.

Weight, temperature, amount and kind of food, and body excretions were recorded. Tables give the data in full. The author con cludes that there is no relation between the per cent loss of weight, or the quantity of food ingested, and the “ transitory fever of the newborn.” The probable cause of fever is the absorption of protein products from the intestines.

In ^the case of 5,000 women confined in the Charité at Berlin between January, 1907, and January, 1909, the author studied age, height (in most cases), number of pregnancy, and occupation of the mothers, and length, weight, and head girth of their infants. Children are separated in the eight tables by sex and by legitimacy. Boys were regularly larger than girls. The length and weight of infants rose continuously with age of the mother to their maximum when the mother was 28 to 35 years. These same values increased with each additional pregnancy up to the fourth, after which they remained about the same. Legitimate boy infants were larger than illegitimate; with girls the reverse was true. Domestic servants had larger children than laboring women. Dimensions of children were proportional to height of the mother. H aake, H .: “ Über die Gewichtsveränderung der Neugeborenen” [On the variations in weight of newborn infants].

Charts from the author and other authorities give computed comparative curves of development. Table 1 compares the measurements taken with the height as a modulus, grouping by age and giving the number of cases for each observation Table 2 gives the measurement of the body parts according to ages. Table 3 gives the relation of weight to linear dimensions and of lung capacity to strength. Table 4 gives the strength of muscle groups by ages. Author’s conclusion : Vertical and horizontal growth alternate. The weight at different ages varies either as the product of height, the interacromial breadth, and the depth of the abdomen, or as the product of the height and the depth o f the chest squared. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis to PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD 275 H a ll, Mrs. W .

The purpose of the article is to dispute the contentiön that the child’s weight increases with the mother’s age only until she reaches 25 to 29 years, after which there is a steady decrease. The author collected information on 4,449 cases in a maternity home in Berlin and presents his data in tables giving the children’s weight according to sex and mother’s age. He found that the weight of the infant increases with the mother’s age until she becomes 44 years old and also with the number of preceding chlldbirths. 285 H edger, Carolina: “ The school children of the stockyards district.” Transactions of the Fifteenth International Congress on Hygiene and Demography, 1912 [Washington], vol. 3 (1913), pp. 170-188.

A discussion of the many phases and factors involved in the physiological loss of weight following birth, the discussion being based on previous publications by others and on the writer’s own observations during eight years in the Breslau’s Woman’ s Clinic of 1.581 infants .that were kept over 10 days in the clinic and were not subject to severe illness. These infants belonged to the lower classes, had an average birth weight of 3.262 grams, and were 97.5 per cent breast fed. receiving five meals a day. After taking up in turn many details on the initial loss and showing that it is lessened by beginning early to feed the infant, the author considers from his experience with 8,441 infants the harmless transitory fever accompanying the initial loss. 290 H eller: “ Physiologie der Neugeborenen” [Physiology of the newborn].

The same amount of milk was given in five meals to 200 children, six meals to 70, and seven meals to 20. Of the first series 10.5 per cent reached initial weight on the ninth day, of the second group 10 per cent, and of the third group 15 per cent. Tests of blood-sugar content on 12 newborn and 3 premature Infants by Bang’s method showed that this content lies within the same limits as 'in the case of older infants and adults. It remained constant in spite of variations in amount and time of meal, etc. Temperature, on the other hand, as tested on 52 children showed great variation, due perhaps to abnormal metabolic processes. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 42 291 292 298 294 295 296 297 PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD H ellm uth, K arl, and von W n orow sk i: “ Variationsstatistischer Beitrag zur Frage des Einflusses der Jahreszeit auf das Körpergewicht der Neugeborenen ” [Contribution according to variation statistics con cerning the question of the effect of season on body weight of the newborn].

New York City, the author Secured a series -of measurements of height and weight of about 300 boys who had been measured at least three times a year “ over an appreciable length of time.” Measurements were taken with outer clothing and shoes removed. • Weighing was on an ordinary scale and height was recorded from a feet-and-inches recorder attached to the scale. In the statis tical computations allowance was made for inaccuracies clue to the use of this • instrument. Comparison of the results with statistics from a public school for boys with negro-white racial background showed the colored orphanage children lighter in weight and smaller, year for year, from 5. to 16, than public-school children of the same racial type, the differences being about the same as those found by Boas between Hebrew children in and out of orphanages. ----------- “ Some observations on the growth of colored hoys.” American Journal of Physical Anthropology [Washington], vol. 7, (1924), pp. 439-446. One thousand and six boys of Public School 89, New York City, a mixed racial group of low economic standing, were measured as to height and weight by the author. Height was measured with shoes, to the nearest centimeter, on a wooden measuring rod with a projecting arm. Deduction was made for the heel. Weight was taken without coats, sweaters, or overcoats, with an ordinary scale. Age was checked with the school record,; calculated in years, months, and days, and tabulated to the nearest half-year.

Lelrlmch der Kinderheilkunde [Leipzig], vol. 1 (1911), pp. 1 - 12 . After describing changes in growth between infancy and maturity the luthor asserts that all growth proceeds according to laws. These can be ascertained by weighing and measuring either many children of the same age or tl e same children at different ages. The first table, compiled from Camerer and others gives weight of nurslings from 4 to 5.2 weeks old and of boys and giiis sepa rately from 2 to 18 years old. Two tables from Camerer, Lansberger, et al., give the length during the first year, and another table the height of toys and girls separately for each year up to 19. From these data the author draws the conclusions that growth both in weight and in height shows periodical fluctua tions, being retarded in the third quarter of the first year and during the years ^ • iTx 9 to 13 in boys, and that increase in height and increase in weight are not congruent— height increases slightly between November and March, considerably between April and August, whereas weight increases from August to November.

Study of 17 normal newborn infants in a maternity hospital in Berlin to determine the nature of the “ physiological loss ” in weight. The author dis agrees with the theory that the decrease is due to an increased output of the infant’s body accompanied by small intake and attributes it to the discharge of meconium ; he says it can not be consi dered as a real decrease. He also found that there is a very small real decrease amounting to 10 to 20 grams and due to the decomposition of albumin and evaporation of water through the skin.

Subjects were weighed stripped, once a week, and heights measured (method not given) every three months except in the third quarter. The author found that more than 90 per cent of the total increase in weight was made between June and December; that weight variations in individuals were more marked in the winter-spring than in the summer-fall period; that the general form of the curve of growth in weight was common to all subjects studied. Weather conditions showed little influence. Growth in height either was continuous or was more rapid at the period of rapid growth in weight. 315 H öjer, J.

The a'uthor studied the weights of 550 infants in Stockholm under 1 year of age. The children were weighed at birth ; then once a month during periods which varied from several weeks to nearly one year. Tables give the weight and increase in weight according to the method of feeding (breast, mixed, artificial) and length of the observation period. Swedish, Norwegian, and German breast-fed infants showed similarity in regard to gain in weight. The artificially-fed infants showed a much slower gain than those at the breast or on mixed feeding. The time required to double the original weight was found to depend mainly on weight at birth. When the course of growth was similar doubling of the original weight took place within 164 days in the case of children weighing at birth 3,500 grams and within 112 days in the case of those weighing 2,500 grams.

The amount of decrease and increase the author thinks, depends on the care received by the child. 318 H olm gren, I . : “ Über den Einfluss der Basedowschen Krankheit und verwandter Zustände auf das Längenwachstum nebst einigen Gesetzen der Ossifikation ” [Influence of Basedow’s disease and related conditions upon height, together with some laws of ossification], Nordiskt Medicinskt Arkiv (Inre medecin) [Stockholm], 1909, vol. 9, ser. 3, no. 5, pp. 1 -1 1 7 ; 1910, vol. 10, ser. 3, no. 1, pp. 1-185, and no. 2, pp. 187-247.

Em m ett: Standards for growth and nutrition. Am. J. Dis. Child. [Chicago], vol. 16 (1918), pp. 359-375. The author discusses three standards of nutrition susceptible of application to large groups of children : (1) The weight-to-height relationship, (2) the annual rate of increase in weight and growth in height, (3) the general app-arance of the child. By a comparative study of 1,774 observations made by a physical director on 350 boys of a favored social group whose weights were taken semi annually, without clothing, for a period of years, with the studies of Porter, Hastings, Boas, and Bowditch, be shows that wide variations make the weightfor-age relationship of little value in determining nutrition. By similar analysis he shows that height-age curves are unreliable. In weight-to-height curves he finds surprising uniformity, pointing to the value of the weightheight index. His data also show the value of the record of annual increase in height and weight as a nutrition index, and the fact that growth is more rapid in summer than in winter. Deductions from any measurements, he feels, should be modified by inspection of the general appearance of the child. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 46 320, 321 322 323 324 325 326 PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD H o lt, L.

An original study of records of length and weight of 12,803 newborn infants at a maternity hospital in Dresden, 61.8 per cent of whom were mature. The author considers length and weight as the most important characteristics of maturity. He discusses in detail his own findings (giving a small number of statistics) and those by a number of other writers. The weight and length are affected by the child’s sex (boys are heavier than girls) ; mother’s age (younger mothers have larger children) ; and number of previous births (first-born chil dren are lighter than those of subsequent birth). Race affects the size; women of the taller northern races give birth to larger children than southerners, and large parents have larger children than small parents.

An account of a physical examination made by the author of 733 boys and 283 girls ranging in ages from 14 to 17 years and attending an industrial con tinuation school in a German city. The author gives the average weight and height for each year of age for both sexes, and for the boys correlates these data with occupation. He found that the figures so obtained were for both sexes one or two years below the average for the corresponding ages.

Two weight curves and a table giving the amounts of milk consumed, with its caloric value and the energy quotient for the first 159 days of life are included. During the first month an increase in weight corresponded to an energy quotient of more than 100, usually 120. After that the quotient became lower, approaching Heubner’s value of 100.

All data were obtained at the bureau’ s own nursery school and city and country school, the physical measure ments by the school physician. The data on physical growth include tables of monthly measurements of weight and height of several individuals from 1.4 to 9.8 years of age, and a table showing the relation of the weightheight index to chronological age, to pulse rate, .and to blood pressure in boys and girls under 13 years of age. Repeated measurements at regular intervals of weight, height, pulse rate, and blood pressure of the same children showed wide variations from the established norms for certain groups. Although the ratio of weight to height increased with chronological age, small groups at each age showed wide variations from the norm. Blood pressure was influenced to a greater extent by weight-height index than by chronological age. Pulse rate decreased with increasing chronological age and with increasing weight-height index.

He found that the children in the poor group were shorter than those in the well-to-do but had a larger chest circumference. This is attributed by the author to the fact that poor children are out of doors more, even in cold weather, than children in wellto-do families. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 48 333 334 335 336 337 338 339 PHYSICAL GROWTH AND.

The author reviews the literature on ¡periodicity of growth of the young child and gives a brief account of the study of weight, height, and chest circumference of his own five children (ages not given) during several years. The children were weighed several times daily and the quantity and quality of their food noted. On the basis of his own findings and those obtained by other writers he concludes that there is a law of periodicity of growth, namely, that the rate of growth varies with the seasons. In his own children he found the increase in weight particularly rapid in the fa ll; it was slow in the winter. In the summer the weight decreased. No explanation is given.

The author describes in detail the development of his sixth child, a boy, who was breast fed to the age of 11 weeks; then in addition to mother’ s milk received a barley decoction, and at the age of 3 months and 9 days began wholly artificial nourishment. The infant progressed satisfactorily imt.il the twenty-eighth week. The author insists that, body weight is not a sufficient criterion of health; that to it must be added consideration of sleep, appetite, good spirits, and especially the objective examination of feces and blood.

He constructs a.chart with a standard height curve from 119 centimeters at the age of 5 to 177 centimeters at the age of 19 ; plots on it for comparison curves from the statistical work of five investigators, and derives a table of percentage deficiency at each birthday for four of the groups.

The author, a school physician in North Charlottenburg, had experience from 1907 to 1915 among 5,000 children of the laboring classes from their birth to the age of 14 years. He notices little injury of young‘ children due to war,probably owing to Federal aid to nursing mothers, though he finds greater fre quency of rachitis and tetanus. Moreover, in the spring of 1915 he gave an official report that according to observations other children, too, seemed to have suffered no adverse effects. A little later, however, school measurements of weight and height proved that the children had sensibly suffered during the war year of June, 1914, to June, 1915. He gives four graphs of weight and height of boys and girls, containing curves for peace years and the war year.

A study of the nature of the physiological decrease in weight of 768 normal newborn infants at a maternity clinic in Marburg. The author divides his cases into 12 groups according to their initial weight. The average decrease amounted to 7.8 per cent of the initial weight for all groups combined. It was caused by the discharge of (1) meconium and later feces; (2) urine; (3) evaporation of water due to perspiration and respiration. The author con cludes that (1) a decrease is present in every case; (2) the physiological decrease ends within two to four days after birth; (3) the quantity of urine discharged by the newborn infant in the first few days is very small owing to the small amount of fluid taken by infant and to loss of water through perspiration. 353 K isskalt, K a rl: “ Die Körperkonstitution der ostpfeussischen Stadt- und Landschulkinder ” [Physical constitution of East Prussian city and country school children], Deutsche Med.

Without giving any definite answer the author takes up the various periods of the physical development of the human, being and the changes in physiology and growth taking place in boys at the end of the seventh, the twelfth, and the fifteenth year, with particular reference to puberty. He shows that the changes taking place at these ages (change of teeth at the age of 7 and phenomena of puberty later) are only partial symptoms of a general modification of condition. This the author considers as an established fact proved by his researches. He is unable on account of lack of data to come to a similar conclusion with regard to the first years of child life. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 52 861 362 363 364 365 366 367 PHYSICAL GROWTH AND DEVELOPMENT OE THE CHILD K örb er: “ Die Durchschnittsmasse ausgetragener Neugeborener und ihre Lebensfähigkeit, berechnet aus den Jahresberichten der Findelhäuser in St. Petersburg und Moskau ” [Average measurements of mature newborn infants and their vitality computed from the annual reports of foundling homes in St. Petersburg and Moscow].

The measurements were taken by physicians, and mostly in April and May in the evening. On an average boys were larger than girls except when 13 or 14 years of age. Puberty usually began at 13 in the girl and 14 in the boy. Christian children were slightly larger than Hebrew. Many of the tables compare these Warsaw children with those of Stockholm (Axel Key), Boston (Bowditch), Turin (Pagliani), and London (Roberts).

He discusses at length their previous illnesses, their height and weight measured without shoes, their muscular condition, their pad of subcutaneous fat measured over the biceps, their bony structure tested in the tibia and at the tables are given. The author found that puberty is a period of great growth wrist, and their thoracic perimeter taken at the level of the nipples. Many in all directions save that o f the fat layer; as age increases,' the lung capacity and fat layer, relatively, also increase, and the upper extremities become better developed than the lower.

Monatsschrift für Gehurtshülfe und Gynäkologie [Berlin], vol. 22 (1905), pp. 194-233. The author personally observed 50 newborn infants during their first 10 days of life, measuring their weight and the amount of milk drunk. He recounts the history of such studies in the past and gives bibliography. He hjfnself weighed the 50 infants five times daily, not excluding underweight or pathological cases He divides them into three classes: (1) Cases in which the umbilical cord was severed late ; (2) cases in which it was severed early ; (3) icteric cases. The weights at birth fell between 1,290 and 4,330 grams. They averaged 3,327 for boys and 3,184 for girls. In recovering initial loss, etc., class 1 fared best and class 3 worst. The heaviest infants lost least and recovered loss most quickly. First-born children developed less favorably than others. Girls lost more than boys but recovered more quickly. The author discusses a second weight loss, which he observed in 76 per cent of his 50 infants. 371 Landsberger: “ Das Wachstum im Alter der Schulpflicht” [Growth dur ing period of compulsory school attendance].

The authors studied the chemical make up of premature infants through dissecting two that died a few days after birth and determining the meta bolism of two that were thriving at the age of 1 month. The two 7-month infants that died of asphyxia weighed 960 and 1,420 grams. The methods followed in the chemical analyses are given and also tables of the results, which are compared with those of other investigators. . The composition ot these two infants was almost identical. As compared with normal newborn infants, premature infants have very little fat and a very high water content ; they have about the same amount of nitrogen and a much greater excess ot sodium over potassium. The two infants born after eight months of pregnancy weighed 2,050 and 1,640 grams. The results of metabolism studies of these two infants are shown in tables. To double their birth weight these infants needed 18,800 and 14,000 calories ; a normal full-term infant uses 2 8 .8 UU calories.

An original study of the height and weight of 516 school entrants, hoys and girls in nearly equal numbers, for the purpose of deciding whether the height or weight is more easily affected by unfavorable living conditions. The author found that 78 per cent of the childrën studied by him had an average weight below that of pre-war times, and 54 per cent of the boys and 48 per cent ot the girls were in height below the pre-war average. The author concludes that under unfavorable living conditions the weight is affected more frequently than the height. Larson, J_ H .: “ Butter fat and the child’s weight.” Arch. Pediat.

Vienna, 1858. 188 pp. A study based on thousands of observations by the author and by such students as Habit, Goetz, and Bednar. Proportions of the human body, espe cially of the chest, during infancy and childhood, and pathological conditions, are considered. From his study of growth the author derives general law3. For instance, human development involves unities of 276-—276 days of intrauterine life, 276 months of extrauterine growth. This time is also divided into two periods in the relation of 6 to 17, in the former of which most of the develop ment takes place. More than 100 pages of tables are included. 39 0 ----------- The Law of Increase and the Structure of Man. Vienna, 1862. 12 pp. During nearly seven years the author measured the parts of the body of 300 individuals of both sexes and different ages. The whole frame of a human being, he contends, can be derived for any age from seven fundamental dimensions : Length of head, of neck, of sternum ; distance from xiphoid cartilage to pubic symphysis, total length of leg, elevation of internal malleolus over sole of foot, and length of clavicle. With these dimensions is used a system of mutually intersecting and tangent circles, which remains the same for all ages. The whole increase of the body comprises 24 epochs covering 25 years. The first epoch occupies the first solar month; each following epoch is a month longer than the epoch preceding. There is a subdivision into, three sections— the first embracing 21 months, the second the next 150 months, and the third the one hundred and seventy-first to the three hundredth month. A detailed table covering these 25 years gives measurements in centimeters for 25 important parts of the body.. Two diagrams of a newborn child and of a young man, with the circles drawn, give further anatomical measurements. 391 Lipiec, M elanie: “ Über das Wachstum der polnischen Jüdinnen ” [Growth of Polish Jewesses], Mittheilungen der Anthropologischen Gesellschaft in Wien, ser. 3, vol. 42 (191 1-12), pp. 115-195, 281-284. The author discusses her measurements of 340 Polish Jewesses, taken with the subjects stripped. Those from 10 to 18 years of age were in institutions for the poor in W atsaw ; those 18 and 19 years old were students in Zurich and of a better class socially. Many graphs, 143 tables, and 7 pages of measurements of height, torso, and extremities. Repeated comparisons are made of the other Jews and of other races. The author concludes that growth between the ages of 10 and 19 is 20 per cent of total grow th; that from 10 to 15 years of age the growth is more rapid than from 15 to 19; that from 15 to 19 growth in breadth is greater than growth in length; that modifications of indexes are not great; and that growth energy in the later years is greater in males than in females. 392 Lips, Friedrich: Über die Gewichtsverhältnisse der neugeborenen Kinder zu ihren Placenten [Relation ot Weight of Newborn Children to their Placenta].

Anthropologischer Anzeiger [Stuttgart], vol. 1 (1924), pp. 76-95. Several tables and diagrams show the height and weight of boys and girls from 6% to 13 years old for each six months of age before the war, and in 1921 1922. and 1923. The pre-war figures were taken by the author trom other writers and apply to nearly 10,000 children in three German cities; the 1921-23 figures were obtained by the author himself from 3,989 children of Munich. The postwar figures show lower averages than those obtained before the war. The author compares the children of Munich with those of Chicago using the figures from Baldwin’s report. For this purpose he gives the weight and height by sex and by city for each six months of life in 15 age groups. He found that in each age group the children of Chicago were taller and heavier than those of Munich. The German figures for 1921 23 were lower in the case of children born in 1914 and 1915 than in the case of those born in 1917. This is attributed by the author to the fact that the former children spent a longer period under unfavorable food conditions than the latter group.

The relationships between intelligence as in dicated by school standing (class and teacher’ s estimate) and height, hair color eye color, and head circumference were worked out in tables, leading the author to the following conclusions: The indirect influence of physical condi tion upon school standing is evident, as poor health interferes with regular work and attendance; the direct relationship is not so evident. The most evident relationship is between head circumference and intelligence, the more intelligent boys having a larger average measure. M atveyeva, V .

From a study of previous works on the subject as well as from personal ob servations the author constructs graphs of the normal weight of a child in Ms first year, in his first 2 years, and in his first 13 years ; also of the normal height in the first 13 years ; of the thoracic perimeter during 13 years, and of the coefficient of robustness from 1 to 21 years. For this coefficient he uses Pirquet’s formula : Height in centimeters, weight in kilograms, and thoracic perimeter in centimeters. In 1906 he made 1,250 observations of children between 7 and 13 years of age, and after that time many other series of meas urements. In addition to the above factors in normal development the author discusses dentition, walking, changing proportions in a child’ s form, and sec ondary sexual characteristics. ------- “ Le développement physique de l’enfant ” [The physical develop ment of the child].

The author gives his data in numerous tables, compares his results with those obtained by other investigators, and concludes that the physical development of boys is superior to that of the girls, that the annual rate of gain in height between 8 and 13 years of age decreases gradually, and that the gain in weight and chest circumference is fluctuating. The girls at the age of 13 show accelerated growth of the body. Bibliography.

From a careful consideration of the daily weights of 12 newborn infants and of 6 from 3 to 8 months old, all normal, for which the author presents curves, he comes to the conclusion that growth consists not only of progress but of progressive phenomena. He discusses dentition, puberty, the patho logical affections of growth, and the so-called “ fever of growth.” M uffang, H .: “ Écoliers et étudiants de Liverpool” [School children and students of Liverpool].

The author had measured, according to his direction, 148 English boys and 79 English girls 9 to 14 years of age in a public school ; 485 pupils in the Liverpool Institute (commercial and Latin school), aged 7 to 17; 86 students in University College; 27 professors; and 74 subjects engaged in commerce or industry. Data are given for height taken in shoes without allowing for heels ; color of hair and eyes ; shape of the nose ; cephalic index. He found the average cephalic index 78 or 78.5. The social classes varied more in stature than in cephalic index. His observations confirmed those of other scientists as to variations in growth at the age of puberty. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GENERAL G RO W TH IN W EIGH T AND H EIG H T 452 453 454 455 456 65 M urray, M.

In ascertaining the relation between physical characteristics and social con dition the author recorded the height, weight,. thoracic perimeter, respiratory index, force of muscular contraction, cephalic circumference, height of forehead, cephalic index, probable cranial capacity, color of eyes, color of hair, and some facial anomalies of 2,451 boys and 726 girls from 7 to 14 years of age, all French Swiss, in the elementary schools and first two classes of industrial College or high school of Lausanne. The data collected- are shown in 27 tables in 22 pages of figures at the conclusion of thè article. In .general, the author decides that, other things being equal, the children of well-to-do families are superior to poor children in height, absolute and relative weight, thoracic strength, cephalic circumference, height of forehead, and cranial capacity ; the same superiority holds, too, in the brachycephalic and dolichocephalic types of the rich over the poor.

In several tables he gives the average weight, height, chest circumference, vital capacity, and muscular force for each year of age. The boys were measured shortly after their admission and about 200 once a year in the three succeeding years. The author found that the boys grew very rapidly while in the colony, which he attributes to the favorable living conditions in the institution as compared with the boys’ previous surroundings. For the purpose of comparison author also studied over 200 (exact number not given) girls in a high-class boarding school. In several tables he gives their age, weight, height, vital capacity, and muscular force, measured once a year for three years. He found the values far above the average for girls of the same ages, and the height and weight of the girls greater than those of the boys of the same age, which is contrary to the usual findings. This he attributes to the unusually good living conditions in the girls’ school. Pakhom ov, D. A .: “ Nabliudenia nad fizicheskim razvitiiem vospitannikov S.

No definite relation between age of mother and child’s weight was noted. Many tables show the weight of the infants in relation to sex, number of mother’s previous pregnancies, her age, marital status, duration of prenatal rest in a maternity home, and her economic condition. The author concludes : (1) The average weight increases with the number of pregnancies, but the difference becomes constantly smaller. (2) Children o f well-to-do par ents are born heavier than those of poor parents ; the difference is still greater when the mothers are unmarried or when they spend their entire pregnancy period outside of an institution. (3) The differences in weight caused by social factors are as great as, and even greater than, those caused by the sex of the child or the number of previous pregnancies.

Archiv für Gynäkologie [Berlin], vol. 122 (1924), pp. 208-238. Original study of the part played by exogenic factors in the intrauterine development of the human being. The authors studied 14,500 newborn infants in Vienna from 1912 to 1922, inclusive. The cases are divided into four groups according to the mother’s marital condition and according to the care she received in the antenatal period. The authors found that a decrease in weight amounting to about 350 grams took place. since the war in all the abovementioned groups. This is attributed by the authors to the shortage in food, particularly fats and proteins, due to the war. They conclude that a reduction in the calories, proteins, vitamins, and other elements in the mother’ s food checks the growth of the fetus. Numerous references to other writers. Tables and diagrams.

The author investigated the weight of 29 newborn infants at the university clinic at Kazan, Russia, the children being weighed nine times a day for six days. The author gives in tables thè results of each weighing separately for each case, and after a detailed discussion of his results he presents 18 conclusions. He found a decrease of weight in every case. It took 65 hours in the case of boys and 70 in the case of girls, to make up the loss. More than one-half of the loss was due to the discharge of meconium. In the first few days metabolism takes place at a higher rate in boys than in girls. Peterson, O.

Development is advanced according to amount of muscle and fat. Girls are plumper than boys but boys are usually heavier. Boys have relatively greater length and larger skulls. The latter fact probably accounts for their greater mortality at birth By studying 400 newborn children the author found that the heads of the first born are not so long as those of other infants. Pfaundler, M .: “ Körpermassstudien an Kindern” [Studies of bodily measurements in children]. Ztschr. f. Kinderh. [Berlin], vol 14 (1916) pp. 1-148. The author discusses the possibility of bringing variations in size of children under mathematical laws. After considering Galton’s accidental curve he treats at length Gauss s curve based on general law of probability and concludes that height does actually follow Galton’s law. Besides height he discusses body measurements in various classes, discards the parabola as a growth curve, and detects a relation between weight and conception time. He perfected a device for directly determining surface and tested the Vierordt-Meeh coefficient as an mdex o f stature. He discusses the “ law of surface area ” and body volume and body thickness. He refers to investigations on children conducted under his supervision by Riedel, Skibinski, Diskanski, Matusiew-icz, and analyses the work done by_ Weissenberg and others.

About one-half of the children belonged to families of factory workers ; the others were peasants. The purpose of the investigation was to ascertain the differences in the physical development of the children of these two groups. The author found that as regards height, chest circum ference, and annual gain in both, the advantage, other things being equal, was on the side of the peasant children ; and in each of the groups families with the higher income had the better-developed children.

By the same system the boys and girls o f the fifteenth and thirty-first district schools, between 7 and 14 years of age, were weighed and measured in March, 1917, and February, 1918. Thus the author had data on more than 1,200 children in one of the schools and on 1,200 to 1,500 children in the other school for each of the years, 1914, 1917, and 1918. The system of measurements is described, and the results are presented in six tables. The more prosperous children of the one school showed better values than those of the other. Girls showed superiority over boys from the eleventh or twelfth year on.

From measurements of 33,500 St. Louis school children (for method see No. 503 this section) the author derives tables and graphs based upon distribu tion by school grades, from which he concludes : (1) Precocious children are heavier, taller, have larger chest girths and wider heads than either the mean or average child of same age, and dull children, vice versa. (2) The compara tive rate of growth of dull, mediocre, and precocious children of the same sex is the same at all ages from 7 to 16, inclusive ; the acceleration in weight preceding puberty takes place at thé same age, and the point at which girls become heavier than boys is the same. (3) No child whose weight is below the average for his age should be promoted beyond the average grade for his age without physical examination. ------ — “ The relations between the growth of children and their deviation from the physical type of their, sex and age.” Transactions of the Academy of Science of St. Louis, voi. 6 (1893-1894), pp. 243-250.

From measure ments.of 33,500 St. Louis school children (for method see No. 503 this section) he derives tables showing number of observations (in groups), average, probable deviation, relative annual increase of average, and relation of probable devia tion to average, and concludes that the physiological difference between the individual children in an anthropometric series and the physical type of the series is directly related to the quickness of growth. ---------- - “ The relative growth of individual Boston school boys.” Ameri can Journal of Physiology [Baltimore], voi. 61 (1922); pp. 311-325.

Ztschr. f. K vn der\ [Berlin], vol. 37 (1924), pp. 269-270. The purpose of this study was to ascertain whether there is a relation between the increase in weight and the decrease in body temperature in infants. The infants (number not given) were fed five times a day every four hours ; the food was in all cases equal in amount and composition ; the infants were weighed and their temperature taken every four hours. The author found that the daily weight of infants over 3 months old varies froth 150 to 500 grams. It increases in the afternoon, reaches its- maximum at midnight, decreases in the early morning and undergoes very little change throughout the forenoon. The temperature runs a course very similar to that of the weight. These fluctuations in weight and temperature, the authors think, are produced by the transition from sleep to wakefulness and by the accompanying variations in the intensity of metabolism. They found no direct causal connection between the fluctuations in weight and those in temperature.

After discussing the works of Bouchaud (1864) and Woronoff (1882) on extreme losses of weight in children the author considers the question how great such a loss of weight may he and still permit recovery. Sifting ma terial in the Breslau Children’s Clinic covering 10 years he selects 38 cases o f children 2 years old or younger who lost more than one-fourth of their weight. Thirteen cases belonged to the first and second months ; 17 were from the third to the sixth, 8 from the sixth to the twenty-fourth. The smaller the total weight, the larger the relative loss. The most frequent causes of decrease in weight were tuberculosis and nutritional disturbances. Among the 38 there were 8 cases of the former, 23 of the latter. From the 23 the author selected 7, for which he gives long case histories and weight curves. The greatest loss in an infant that recovered amounted to 34.8 per cent of its weight. Quetelet, L. A .

R. : “ Physical measurements of pupils in Mostar, Herzegovina (A u stria).” Translations of the Fourth International Congress on School Hygiene [Buffalo], vol. 5 (1914), pp. 541-550. The original purpose of this study was to investigate thoroughly the relation between bodily development and intellectual activity of school children. A total of 4,634 persons between the ages of birth and 65 years were measured, but this paper relates only to pupils from the high gymnasium for boys, the elementary and secondary public schools of Mostar, All were Serbs or Croats. Measurements were made of standing height, sitting height, circumference, length, width, and height of head, length, width of right and left ear, and body weight. Technique is described, and results are tabulated. From tables, of average values the author found very slight correlation between measure-, ments and mental capacity. Since average values studied and evaluated with reference to the distribution, of cases, maxima and minima, and so forth, give a variety of results, the author concludes that school anthropology has not yet reached the stage of definite conclusions.

The author’s research rests on measure ments made in the summer and fall of 1902 on 2,509 healthy and 298 sick children, from birth to 15 years of age, in schools, clinics,1; and other institu tions, o f Kiel, Lubeck, and Alsterdorf. Of the healthy children 1,468 were boys, 1,041 girls. The investigation involved details of body length, size of head, and family history. In addition to giving' comprehensive tables of fig ures the author discusses many individual cases, being especially interested in incipient hydrocephalus. He finds that boys are larger than girls, except between the ages of 6 and 14, and that the head has assumed its definitive form by the seventh year. The children were almost all brachycephalic, the girls showing slightly lower averages than the boys. Especially, intelligent children had mean values, for their ages, of head measurements and indexes. --------- . “ Beiträge zur Frage des kindlichen W achstum s” [D ata on the question of children’s growth].

The meas urements are taken in summer clothing, shoes excluded; chest measurements according to Frolich’ s methods. Tables and graphs give height, weight, and annual growth o f boys and girls; other tables give variations in height and mass, chest measurements, _the quotient of weight in grams divided by height in centimeters, and comparison of boys and girls of richer and poorer classes in Berlin and other German cities with those, respectively, of Sweden, Denmark, England, Boston, Turin, and Warsaw. The author comments on a retardation m growth of boys from the age of 9 or 10 to 13 or 14, and on earlier pubertal acceleration in girls at 11 to 14. The more prosperous class is better developed than the poor class, the chest averaging 3 centimeters greater in circum ference. The Berlin children showed superiority in height to all others except the English. °v R ip ley, W .

From the work of various investigators in the three countries mentioned the author discovered that Australian newborn infants weigh more than those born in the eastern United States, and the latter than those born in the British Isles. He discusses social and economic conditions in the three coun tries and concludes that birth weight of infants of same race is a sensitive criterion of social and economic environment. 547 -------- — “ Studies on the growth of m a n : I.

I. A curve for the latter part of intrauterine growth is plotted by mathe matical processes, the basic data being the weight of premature infants in South Australia. This curve is a continuation of the postnatal weight curve with an indentation at birth. There is no indication of more than one growth cycle in utero after the implantation of the embryo. The human growth periods are (1) to the implantation of the embryo; (2) to the age of 1 year; (3) to the age of 5.5; (4) to adult weight. The maximum velocity of growth is at 12.5 years in the female and at 14.5 years in the male. II. The infants were weighed one week after birth. A comparison is made between the observed loss and gain in early infancy and the presumptive weight if the curve of growth were not depressed by birth. 548 —— — “ Studies on the growth of man. III.

From data supplied by infant-welfare associations in London and Leeds on about 2,000 infants a curve is derived by indicated statistical methods, show-, ing increase of weight in males and females of British parentage during the first, year. Comparisons are made with data on South Australian infants of British descent. The author finds that though the absolute amplitude of the first growth cycle in man is affected by environment the specific velocity of the growth process is affected very little; that the period of half completion of the cycle is later in females than in males and in Australia than in Eng land.

To investigate the initial loss of weight of the newborn the author used Strubell’s refractometric method of determining the breaking exponent (n d) of the blood serum. He examined four healthy breast-fed infants in a private clinic for almost two weeks after birth and gives in this article their case histories, and for each day the body weight, n d, amount of food taken, and a curve of refraction, of weight, and of nourishment. There is an obvious parallel between the weight curve and the refraction curve. The author believes that the initial loss is due primarily to a loss of water. Infants drink nothing their first day, little on the second day. Their weight falls lowest on the third day and equals weight at birth on the sixth day or later.

To discover whether dolichocephalic and brachycephalic young men belong to distinct types, mentally and physically, the author took record cards of 1,100 Harvard students who had been recently examined and grouped them according to cephalic indices. The dolichocephalic group were found superior in height, weight, strength, and athletics ; the brachycephalic in college rank. 570 ----------- “ The physical development of women.” Scribner’s Magazine [New York], voi. 5, February, 1889, pp. 172-185.

Girls showed greater variation than boys. The heavier the infant the greater was its initial loss. The weight was least where the mother was small, under 20 years of age, hard-working, tuberculous, etc. The curve of the total N elimination was parallel to the curves of weight and temperature. Prema ture children showed a greater elimination of N in the urine and! more icterus, as well as greater loss of temperature. von Schaetzel, Peter: Über den Einfluss des Alters der Mutter und der Zahl der vorausgegangenen Schwangerschaften auf Länge und Gewicht der Neugeborenen [On the Effect of the Mother’s Age and the Number of Previous Pregnancies on the Length and Weight of the Newborn].

Quotations from Hecker’s study of 4,449 cases are included. The author found that the infant’s weight in creases with the mother’s age, the maximum being reached at 30 to 34 years, after which there is a decrease, with again a slight increase for women over 39 years old. The weight was also found to increase with the number of pre vious pregnancies. Length was not . affected by cither the mother’s age or the number of previous pregnancies.

The author presents seven pages of tables containing 250 measurements o f the transverse line on the nail on the thumb, middle finger, and little finger of young infants, as well as graphs and diagrams of the same. He explains that such lines are not due to syphilis ; they may arise from any disturbance of health, and also regularly appear from about the fifth week to the thirteenth week as a physiological phenomenon. He therefore traces the development of the normal infant nail from birth on. This line, since it has a definite progress, possesses value as a sign of age. It appears also on the toenails. He concludes that the vicissitudes of the birth act affect the matrix of the n a il; four to five weeks afterwards the line on the nail appears and grows slowly out. ------- —- Ernährungsstudien beim Neugeborenen [Studies in feeding of the newborn].

The author is of the opinion that the physiological decrease in the infant’s weight taking place within the first days after birth is due to insufficient intake of food and can be avoided to a considerable extent by proper feeding. The article contains a detailed account of the methods of feeding used for this purpose under the author’s direction in 751 cases. -----------“ Zur Frage der physiologischen-Körpergewichtsabnahme des Neu geborenen” [Question of physiological loss of body weight in the new born].

The author in December, 1915, measured 400 boys and girls 1 to 13 years old as to height, weight, chest measurements, girth of lower arm, and force by Collin s dynamometer. The children were in Schaaksvitte and Kirche-Schaaken, Königsberg, of LithuamanPrussian stock, poor folk, living in unfavorable hygienic and social conditions but sturdy from their active life. Infants were regularly nursed by their mothers. The data' are placed in tables and compared with those of Camerer, Quetelet, Schmid-Monnard, et al. Boys were in general larger than girls, but the latter showed an extraordinary increase from 11 to 13 years of age. In chest measurements (expiration) boys from 6 to 13 years showed an average annual increase of 1.15 centimeters and girls of like age 1.3 centimeters, whereas most authors report an increase of 2 centimeters. The military fitness o f this population was 90 per cent. The soldiers were invariably taller than the average for the whole German Empire. 586 Schlesinger, E u gen : “ Das Wachstum der Knaben und Jünglinge vom 6 bis 20 Lebensjahr” [Growth of boys and youths between 6 and 20]. Ztschr. f. Kmderh. [Berlin], vol. 16 (1917), pp. 265-304. A careful study made of about 10,000 Strassburg youths 6 to 20 years of age. The author groups his material according to social plane and further according to development and constitution of the individual. All measurements were made by the author himself. To avoid variations due to season and hour he made the examinations in the morning and for the most part in the spring. He counted the second half year as a whole year and allowed for weight of clothing. His conclusions -are expressed in numerous curves and tables, and long discussions He discerns four periods of growth : 6 to 9, 9 to 10 or 11,,10 to 15 or 16, 15 to 20. Throughout childhood growth in height is greater than in weight. The variation among individuals of a given age increases as boys grow older. The best class presents a greater height and relatively lighter weight than the others. Inferior children form at first 4 per cent of the whole number, then 2 per cent. Inferiority among apprentices is 8 per cent. Inferior boys are three to four years behind others. They are peculiar also for periods of growth cessation. Anemic, neuropathic, or rachitic children show no in feriority in height. Chest girth shows little relation to height but has a much closer connection with weight.

Beginning with an account of the early studies of growth, namely, those by Quetelet, Camerer, Pirquet, and Pfaundler, the author proceeds to discuss in detail the methods of examination, laws of growth, differences in growth due to sex, race, and individual constitution, periodical fluctuations in the process of growth caused by changes in seasons, periods of accelerated and retarded growth, the conditions affecting growth, such as environment, general state of develop ment, underfeeding, school work, illness, disorders in the functioning of the endocrine glands. He quotes in detail figures of the weight and height of chil dren obtained by various persons in 23 cities of Germany after the war, also by Camerer, Baldwin, and several other investigators. He gives no new statistical data of his own, but quotes those he published in reports of his studies made in 1911-1918 on the height, weight, and ponderal index of school children, Twenty-five tables and a list of over 300 references. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GENERAL GROWTH IN W EIGH T AND HEIGHT 588 . 588 589 590 591 592 593 85 Schlesinger, E u g e n : “ Unterschiede im Wachstum bei Schulkindern und jungen Leuten von verschiedener Konstitution und aus verschiedenen Bevölkerungsschichten ” [Differences in growth among school children and young men of varied constitution and varied classes of society]. Deutsche Med. Wchnschr. [Leipzig], vol. 43 (1917), pp. 1607-1608. From observations on 10,000 boys between the ages of 6 and 20, in private schools, polytechnic schools, public schools, etc., the author derives four periods of grow th: The first from 6 to 9, fairly rapid, more in height than in weight or in girth of chest; the second from 9 to 10; the third from 10 to 15 or 16, of rapid growth, that in height being greatest at 14 and in weight at 15; and the last period of slight increase in height and lively increase in weight. Differences in classes are due to heredity more than to environment. Thin, anemic, and nervous children show no inferiority in height. Defective children show long periods of stagnation in grow th.. The chest development is related rather to weight than height. A retarding effect in growth can be detected at 6, due to the beginning of school; at 14, among boys beginning to w ork; among the upper classes at 16, the age for matriculation examinations. * ---------- - “ Wachstum, Ernährungszustand und Entwicklungsstörungen der Kinder nach dem Kriege bis 1923 ” [Growth, state of nutrition, and disorders of development of children between the end of the war and 1923].

This article, which is a sequel to a previous study, is ¡a general discussion of the weight and height of about 3,100 school children and 300 infants and kindergarten children who were weighed and measured many times every year between 1919 and 1923. The author gives no tables; for the method of his investigation he refers the reader to his previous articles. He found that the retardation in the children’s growth first became noticeable in 1917 and was greatest in 1920, when height was 4.3 per cent below norm al; weight in the period from 1917 to 1920 was from 4 to 12 per cent below normal. In the years 1921 and 1922 both height and weight reached pre-war standards; in 1923 they again went below normal. ----------- “ Wachstum, Gewicht, und Konstitution der Kinder und der herangewachsenen Jugend während des Krieges ” [Growth, weight, and constitution of children and youths during the w ar].

The measurements were taken from 4 to 6 p. m. at intervals of three to ’ six weeks between June 22, 1893, and August 6, 1894. The author found that height increased from February to August and very little from September to January, and that weight increased not at all from February to June and decidedly from July to January. Illness and mortality are most frequent early in the year, least frequent in the fall. Camerer found the best metabolism from September to November. Vacations had no note worthy effect on growth.

All the children had been breast fed for at least nine months. The author found that the children whose fathers had been in the military service were 600 to 800 grams heavier than those of fathers who did not serve in the' army. This difference became still greater when the order of the child’ s birth was considered. It is known that children of young primiparæ are at birth lighter than children of older pluriparæ, but beginning with the second year they gain in weight more rap idly than the latter. This gain was particularly great in the children whose fathers had been in the military service.

Greifs wald, 1903. 28 pp. Inaugural dissertation (University of Greifswald). The author discusses the weight of 600 infants, healthy and sick, born 1901 to 1903 at the Uni versity of Greifswald hospital. By the tenth day, 48 per cent, had recovered their birth weight, many of them much more than their- birth weight. He examines at length the reasons that may have prevented the other 312 from regaining their initial loss in weight.

Deutsche Med. Wchnschr. [Berlin], vol. 41 (1915), pp. 618-620. The author studied 100 infants (56 boys and 44 girls) horn in the Osna brück School for Midwives, most of whom remained there 12 days. Within that time 45 per cent regained their birth weight, on an average upon the ninth day. The infants were weighed daily. The weight curves were little affected by sex by operations upon the mother, by her loss of blood, or by her tempera ture. The average weight at birth was 3,357 grams. Ninety-four of the mothers had abundant milk. Schwarz, H erm an, and Jerome L. K o h n : “ T h e'in fan t of low birth weight; its growth and development.” Am. J. Dis. Child.

The authors followed the case histories of 272 children with low birth weights f2,500 grams or less)— 166 for 3 months, 130 for 6 months, 100 for 12 months, and 26 a greater length of time. Gains in length and weight were noted and summarized in tables. They found the gain in weight during the first 12 months to he at the same rate as that of the normal child, so that the deficiency was not made up at the end of the first year. Normal length was attained sooner than normal weight. Schwerz, F ra n z: “ Untersuchungen über das Wachstum des Menschen” [Investigations on growth of mankind].

As an army doctor in the Third Field Artillery Regiment of Bavaria the author from 1885 to 1889 exactly measured 1,643 soldiers between 19 and 23 years of age, in height, weight, chest girth, shoulder breadth, and sagittal diame ter of breast. He found that the younger men were superior to the older in height, weight, and breadth of shoulder, but inferior in girth of chest. The last measurement was greatest in heavy laborers. Tall people were relatively heavier than short.

Archiv für Anthropologie [Braunschweig], new ser. vol. 1 (1 9 0 3 -4 ), pp. 1-29. Seven hundred Munich school boys ranging from 10 to 21 years of age and belonging to various classes of society were measured at annual intervals. Each boy was measured from one to nine times, according to his term at the school. The author obtained in this way 3,608 measurements from which he compiled tables of height according to age, differences between maximum and minimum height, and increase In height for each year, and graphs based on the first and the third table, the latter of which he prefers. A table of types of growth shows that the greatest increase occurs in the fourteenth year. Similar tables give the distance between the pupils of the eyes. The minimum is 48 milli meters in a boy of 11 and the maximum 69 in a boy of 16. There follow tables of such distance between the pupils as compared with height ; of skull measure ments of dolichocephalic and brachycephalic human beings ; of men, women, Japanese, and various apes, and of 20 Togo young women ; and graphs of curves representing height, distance between eyes, and increase in weight of brain. Since the distance between the pupils of the eyes, the breadth of the skull, and the weight of the brain increase uniformly, the growth of the first named relative to the size of the body constitutes, other things being equal, a reliable standard of intellectual capacity. But the distance between the pupils need not be great when the forehead is high and full. The best brains accom pany a forehead high, full, and broad.

This material he works over into statistics on the superiority in height and weight of later-born over first-born children. The question is complicated by the fact that boys are regularly larger than girls. With the second child there is a superiority in weight of 182.7 grams ; with the third, of 50.71; with the fourth, of 27.04; with the fifth, of 57.86; with the sixth, of 230 ; with the seventh, of 34.26 ; with the eighth, of 33.33.

Growth from the first month of gestation to 20 years is discussed. Between the ages of 2 and 4 years and 8 and 10 years the increase in weight is relatively greater than the gain in height. Between the ages of 5 and 7 years and 11 and 15 years the growth in height is predominant. 654 Studzinski, J.

All these workers remained in the same occupation during the entire period covered by the study. The report gives in numerous tables for each year of age and separately for the sexes the average weight, height, and. chest circumference and the annual increase of these three measurements. It was found that girls at- the age of 14 were better developed in regard to height, weight, and chest circumference than hoys of the same a g e ; after that the boys became superior to the girls.

After a review of previous works on- the subject the author gives data on three boys and nine girls from a series of four weighings during the first nine days of life. The average weight o f the girls was 2,950 grams, of the boys 3,307. During the first three days the girls lost an average of 185 grams each, and the hoys 117. Table gives data on 40 children born the same year and weighed on the day of birth and day of discharge, usually 15 days later. Average weights for boys on these two days were 3,092 and 3,265 grams, and for girls 3,148 and 3,267 grams, respectively. As causes of initial loss of weight the author suggests weight of meconium, lack of milk, defective functioning of alimentary tract, and profuse perspiration.

The author measured 1,006 Chemnitz school children 6, 9, and 13 years of age who were free from deformities; of these, 500 were anemic and 300 either tuberculous or with tuberculous tendencies. The results are given in tables. The anemic children were little inferior to the normal children, but the tuber culous children were underweight. The boys were also undersized, but the girls at the age o f 13 showed excessive size,, due to coming puberty, which is earlier in girls than in boys.

Data were obtained from records of measurements of naval cadets taken at entrance to the service and four months later for 12 consecutive years. The author found the two measurements insufficient for determination of physical condition and stated that no formula could serve as a means of estimating vital force during the period of growth.

Presse médicale belge [Brussels], vol. 60 (1908), pp. 821-826. The author has already established that in hypotrophie conditions due to chronic gastroenteritis stature is arrested less than weight. For instance, an infant 8 months old had the length of a normal 4-month-old infant and the weight of a 2-month-old infant. This constitutes dissociation of growth. But dissociation is also physiological ; from many mean weights of infants born in French hospitals taken 1 day after birth, 10 days after, and 30 days after, it is shown that in the first 10 days they gain 100 grams and 2.3 centimeters and in the next 20 days 600 grams and 2 centimeters. Four cases are described in detail. Variot, G .: La croissance chez le nourrisson [Growth of the Infant]. G. Doin, Paris, 1925. 339 p p ..

To ascertain mean weight of newborn infants the authors took the statistics for 500 boys and 500 girls at St. Louis and obtained 3,130 grams for the former and 3,020 grame for the latter. For length they took the same num bers from the Hospice des Enfans-Assistés, and obtained 49.8 centimeters for boys and 49.3 for girls. For monthly growth up to 1 year they used the records of the Belleville Goutte de Lait and the Institute de Puericulture des -Enfans-Assistés and found that there existed little difference in weight and length between artificially-fed and breast-fed infants. In the infants observed the weight for both sexes at the end of a year was 91 kilos and the length 71.7 centimeters. A table is given for weight and length of boys and girls for each of the first 12 months as related to the method of feeding.

Weight, height, and chest circumference are given by sex and age. Contrary to other writers the author finds that the absolute weight, height, and chest circumference increase with the years of school attend ance, which he attributes to the happy spirit of the children in the schools investigated by him, to the devotion of the teachers to their work, and to the informality of the instruction, which prevents overwork and promotes happiness.

To compare with these figures he presents a table of men’s and women’s heights as estimated by Erismann, Roberts, Quetelet, Zeising, and Schadow, and curves according to Erismann, Roberts, and Quetelet. Another graph shows the influence of comfort and of occupation upon height and weight. The author justifies his choice of material by the facts that Jews are homogeneous in race and living conditions and that they have the same average height as other Europeans. He points out that general laws of growth persist through differences of race. A growth curve is irregular; males are larger than females; from about 10 to 15 years of age girls are larger than boys. Growth may be divided into these periods: First 2 years of very rapid growth after which a child has one-half of his ultimate height; 2 years to 6 years much slower grow th; 6 years to 10 or 12, slow growth, after which the child has threefourths of his final height; 10 or 12 to 17 or 18, rapid grow th; 17 or 18 to 25, slow grow th; after 25, no growth. The full differentiation according to race, sex, and individual appears after accelerated growth at puberty. -----------Das Wachstum des Menschen, nach Alter, Geschlecht, und Rasse [The Growth of Man as Affected by Age, Sex, and Race].

He compares his measurements with those of Quetelet, finding no great differences, and with those taken of adult Hebrews. Infants show less variation in size than adults, and less difference due to sex. Their energy of growth is very great, especially in the first three months. Their proportions are very different from those of adults, especially in the much greater relative size of the upper body. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GENERAL GROWTH IN W EIGH T AND H EIGH T 729 730 731 732 733 734 735 105 W eissenberg, S .: “ Die südrussischen Juden” [South Russian Jews].

A .]. Archiv für Anthropologie [Brunswick], vol. 22 (1893-94), pp. 13-48. This is a thorough treatment of measurements collected by Dr'. Franz Boas and others, of the school children of Worcester, Mass. The material comprises data on 3,250 boys and girls from 5 to 21 years of age. Sixty-six per cent of the parents were American, 20 per cent Irish, 7 per cent English and Scotch, and 6 per cent from other European countries. The data include weight, total height, sitting height, length and width of head, and width of face. The article contains 5 figures and more than 30 tables, and very full discussions, embracing mean variations, difference of averages, and comparisons between different measurements. Other anthropometrical statistics are also considered. ----------- “ The anthropometry of American school children.” Memoirs International Congress of Anthropology, 1893 [Chicago], 1894, pp. 50-58. The author discusses statistics collected for the World’s Columbian Exposi tion on the anthropometry of school children in Toronto, Oakland, Boston, Mil waukee, St. Louis, and Worcester. He calls attention to differences due to heredity and environment, race and locality, sex and social status; he explains the factors, rate of growth and period of growth, “ shoots ” in growth at certain ages, asymmetry in curves due to precocious children, and the many variations in the period of female superiority. Apparent fluctuations in figures are sometimes due to different mathematical treatment of material. Children of foreign parents are better developed when born here than when born abroad. In the Toronto intelligence tests the “ poor ” students are almost invariably the better developed physically. Both boys and girls are mesocephalic at all ages. W h y te , G. D .: “ Report of the research committee of the C. M. M. A. on the height, weight - and chest measurements of healthy Chinese.” National Medical Journal of China [Shanghai], vol. 3 (1917), pp. 101-113. Data were collected by physicians in different parts of China and compiled in an effort to establish a standard of physical fitness for the Chinese, from height, weight, and chest circumference. About 2,100 cases of both adults and adolescents were reported. Results are tabulated. The Chinese were found to weigh less per inch of stature than Europeans, and to exhibit sufficient racial peculiarities to make special standards necessary. ------------“ The height, weight, and chest measurements of healthy Chinese.” China Medical Journal [Shanghai], vol 32 (1918), pp. 210216, 322-328. Measurements were made on adult and adolescent males and females in different parts o f China. Chest, height, and weight measurements áre given for about -1,000 adolescents. Weight for height indexes and factors for estab lishing a “ norm ” for Chinese are discussed. Southern Chinese were found to be o f a slighter? builld than those of the northern part.

Beiträge zur Geburtshilfe und Gynäkologie [Leipzig], vol. 4 (1901), pp. 291-302. After discussing the work of other investigators on the relation between narrow pelvis of the mother and weight of the child the author gives data on 1.858 normal births between 1894 and 1900 in the obstetrical division of the women’s clinic in the University of Halle. In 358 cases (19.26 per cent) the pelvis was narrow. After classifying material as shown in several tables the author concludes that a smaller average birth weight accompanies a narrow than a normal pelvis. A narrow pelvis does not cause a longer pregnancy. First-born children of mothers with narrow pelves weigh less than those born later. 737 W illia m s, J. W . : Obstetrics. D.

The author describes examination of the state of nutrition of Mannheim school children by the inspection method, with illumination falling directly on ribs. The nutrition is good if no depression appears between ribs, and so on. Of 1,175 boys 6 to 7 years old 18.6 per cent showed undernutrition and of 767 girls of the same ages 13.8 per cent. Tables give average height and weight o f 538 boys and 613 girls between 6 and 13 years with comparative figures for Munich and from Vierordt’s material. A table contrasts findings in height and weight with those of inspection method.

Data for this report were secured from the children attending the school of education connected with the University of Chicago— 404 girls and 201 boys, all of the favored classes. Records were made of height, weight, lung capacity, blood pressure, hemoglobin content of blood, condition of adenoids and tonsils, and rank in scholarship. Details of method are not given. Results are tabulated and compared with existing reports on children of the poorer . classes. The hemoglobin studies are compared with a control series of 100 from the Jewish Home for the Friendless. The author found that the children of the rich were taller and heavier and had greater lung capacity than publicschool children, but they had lower hemoglobin content and blood pressure. The prepubertal increase in development of girls over boys does not appear in her records, the prepubertal boys showing relatively and absolutely greater growth than boys of the public school but a greater loss of vigor and develop ment than girls of the same group.

In two graphs and three tables the author sets forth his own observa tions and those of other investigators. He finds the ages of 8, 12, and 13 years to be the time of greatest variation in growth for girls. During puberty there is the greatest variation in individual growth. From 9 to 10 and 12 to 13 are periods of maximum growth for girls. The maximum growth for boys is from 8 to 9 and the minimum from 12 to 13 with a rise to 14. •---------- ‘ “ Skolebarns vekst. II.

The purpose of the study was to determine the relation between the develop ment of the chest and skull and the increase in weight of little children. The author measured 695 infants in a municipal consultation center in Nuremberg and presents his data in three chart.«.

The author measured 1,051 boys 7 to 14 years old in rural public schools. About one-third of them were measured two or three times at intervals of one year. In several tables the author gives the average height, chest circum ference, and relation between these two measurements for each year of the boys’ age and for each year of school attendance, and the annual gain in height and chest circumference. He also quotes similar data obtained by other writers. In conclusion, the author, contrary to the writers whom he quotes, states that the assertion that the rural schools have a bad effect on the children’s health has no basis in fact because of the shorter school year and lighter pro gram in the rural schools. 759 Zbukoovski, I.

St. Petersburg, 1892. 36 pp. The author conceived the idea that the nutrition of the infant is indicated by the daily gain in his weight, in percentages of his original weight. For this purpose he weighed 7,530 infants who were cared for at the St. Peters burg infant asylum during 1890, prior to being sent to the villages. They were weighed daily during their stay in the asylum, which lasted on the average 26 days. The author found that the average daily gain for infants fed by the mother was seven-tenths of 1 per cent of the infant’s weight at the time he was brought to the asylum, and for those fed by a paid nurse six-tenths of 1 per cent.

The authors advocate ascertaining the anteroposterior and maximum trans verse diameters and the cross section of the thorax of children by Maurel’s technique with the aid of stethograph, compasses, or stethometer, and paper ruled in square centimeters. The child examined is nude, either seated or upright, and the methods of measuring are explained in detail. The thoracic perimeter increases with age but not in proportion to it. It grows rapidly between the ages of 14 and 16. The right half is usually larger than the left. The transverse diameter increases more than the anteroposterior. At every age there is a corresponding, constant, average value for the thoracic index ^(transverse diameter X 100) t t MS average index for the 6 to 16 year period (anteroposterior diameter) is 148. The normal thoracic cross section should be over 200 square centimeters between 6 and 8, over 240 square centimeters between 8 and 10, over 250 between 10 and 12, over 280 between 12 and 14, and at least 350 between 14 and 16.

The human infant at birth has the astragalus, calcanéum, metatarsals, and phalanges, and in a few days the external cuneiform. Later come the epiphyses of tibia and fibula, the internal and middle cuneiform, and last of the ankle bones, the scaphoid. The sesamoid appears on the great toe at 14 years, and tuberosity continues to the eighteenth year. Illness affects the development of the tarsal bones. Development is earlier in girls than in boys.

This concise article with its 40 Röntgenograms on three plates treats the ossification of the human foot from the eighth week of fetal, to the eighteenth year of extrauterine life. After a survey of former observations with X rays the author discusses the fetal period and then states that at birth the foot does not yet show the scaphoid, three cuneiform, distal epiphyses of tibia and fibula, epiphyses of metatarsal bones, and single phalanges in ossified condition. The ossification of the foot is then traced through childhood. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GROWTH AND DEVELOPMENT OE PARTS OP BODY 6 7 8 9 10 11 12 13 111 Ballantyne, J.

A report of an investigation made by the author among Parisian school children, 20 o f whom at each 2-year age period from 4 to 18 years, were measured in May and June, 1901. Subjects from 14 to 18 years of age were remeasured in October and November, 1901. Fifteen measurements (heights, diameters, etc.) of the head are recorded, and total body stature. The author found that the size of skull increased 12 per cent ; that the face increased 24 per cent; that the ophryosubnasal distance had an increment equal to 39 per cent ; that during puberty there was an acceleration in rate of growth of both skull and face.

OP THE CHILD Bloch, A . M . : “ Étude de la croissance des ongles.” [Study of the growth of the nails]. Comptes rendus hebdomadaires de la Société de biologie [Paris], vol. 65 (1908), pp. 335-336. Studying the growth of the nails by moulds of the fingers and toes, the author found, as in previous studies, that trom birth to the age of 5 years the nails of the hand grow 0.06 to 0.08 millimeter a day and from 5 to 30 years, 0.10 to 0.14 millimeter a day; that the nail of the great toe, from 7 to 30 years, grows from 0.04 to 0.07 millimeter a day ; that the seasons have no influence on the growth of the nails. Boas, F . : “ Heredity in head form.” American Anthropologist [Lancas ter, P a.], 1903, new ser. voi. 5 (1903), pp. 530-538. A mathematical study based upon head measurements of 48 families of East European Jews, secured for the author by Dr. Maurice ,Pishberg. A table shows the distribution of cephalic indexes of the 256 individuals, men, women, and children, the indexes ranging from 73 to 91. Results of the study are inconclusive.

Lyon, no. 138, 1897. 80 pp. Thesis for the degree of doctor of medicine (University of Lyon). Fol lowing a résumé of previous investigations, and discussions of the exterior morphology and evolution of the skull and of the principles of craniometry, and cephalometry, the author reports the results of his own measurements of 1.093 normal subjects. He tabulates, in 19 age groups from birth to 24 . years, the number of cases at each age, the stature, the horizontal circumterenee, transverse and anteroposterior demicircumference, transverse and anteroposterior diameter, and cephalic index. On this material he bases a discussion of the general evolution *of the head, of individual variations in the dimensions of the head, and of their relation to stature. Breslau: “ Neue Ergebnisse aus Schädelmessungen an Neugeborenen” [New data on measurements of the skull of newborn infants]. Wiener Medizinische Wochenschrift, vol. 12 (1862), pp. 785-787. To decide whether the skulls of newborn boys are larger than those of newborn girls the author weighed and measured 576 infants (300 boys and 276 girls) at a maternity hospital in Zurich. The skulls of the boys were found to be larger than those of the girls in full-term and premature children even when body weight was the same. Data appear in a table. Brubacher, H ein rich : “ Über den Gehalt an anorganischen Stoffen, besonders an Kalk, in den Knochen und Organen normaler Und rachitischer Kinder ” [Content in inorganic matter, especially calcium, of the bones and organs of normal and rachitic children]. Zeitschrift für Biologie [Munich and Leipzig], voi. 27 (1890), pp. 517-549. The author examined chemically the bodies of three normal children, one newborn, one 28 weeks old, and the third 4 years old. Ample tables give content in water, fat, ash, calcium oxid, magnesium oxid, and phosphoric acid. The skeleton becomes poorer in water and richer in ash, etc., with growing age. Muscles, skin, and intestines lose water content with growth. In the growing organism the requirement for inorganic matter is much greater than in the adult ; is especially great in the fetus and the young child. The infant needs 0.32 gram of calcium daily for the bones alone. It seems that the young organism possesses some storing place other than the blood for its calcium and iron.

A preliminary report.” American Journal of Insanity [Baltimore], vol. 61 (1 9 0 4 -5 ), pp. 687-697. To verify or disprove the assumption that certain types of deformity of the hard palate are correlates of feeble-mindedness, the authors collected about 1,600 casts of the hard palate from public-school children and adults, and from inmates of schools for the feeble-minded. The measurements reported upon in this article are (1) the minimum distance between the first molars, measured horizontally from the bases of the m olars; (2) the maximum height o f the palate above the plane of the gum line; (3) the distance from the line connecting the two first molars to the alveolar poin t; (4) the distance between the canines measured horizontally from their bases. They found no difference in size of palate between feeble-minded and normal individuals and small difference in variability of dimensions. According to their results, the width o f palate remains approximately unchanged from the ninth or tenth year, and there is little growth after the sixth year. Tables are given.

Clarke, J. Jackson: “ Some observations on the temporal bone, chiefly in childhood.” Journal of Anatomy and Physiology [London], vol. 27 (189 2-93), pp. 411-414. The author shows a table on the temporal bones of children from 3 weeks to 20 years old, 19 of the 24 being younger than 7 years. The thickness of the outer wall of the antrum or of accessory air cells, the thickness o f bone between antrum and lateral sinus, vertical distance of posterior and superior point of tympanic bone from best spot for opening antrum, and other features are noted. The author advocates taking the posterior extremity of the tympanic bone as the lower limit of the posterior border of the meatus and the supra meatal spine as the upper limit. Coffin, L. A . : “ The development of the accessory sinuses of the nose.” American Journal of the Medical Sciences [Philadelphia and New York], vol. 129 (1905), pp. 297-312. The author summarizes the statements of many observers as to the time of the appearance of the various sinuses, and from these and his own observa tions of 12 to 15 skulls of infants and stillborn makes the following deduc tion s: (1) But two of the accessory sinuses are present at birth— the ethmoidal cells and the maxillary antrum; (2) the ethmoids and the antrum are constant sinuses; (3) the antrum in infancy occupies a position which makes impossible the usual methods of drainage and cuts off the antral route to the ethmoid and sphenoidal sinus; (4) the sphenoidal sinus makes its appearance shortly after birth ; (5) the frontal sinus appears between the end of the first and th e , beginning of the third year.

By means of frozen sections and careful measurements (not tracings) of the feet of 38 children under 1 year of age and 10 children 1 to 2 years of age, the author found that— contrary to the prevailing opinion that the feet of newborn and very young children are flat— the feet of these children were not really flat but appeared so because of the pad of “fat under the arch. Tables summarize measurements of the length and height of the arch in each foot, for the 48 children, up to 2 years of age. The average height of the arch for infants of 1 year and under was 1.651 centimeters, and for children 1 to 2 years it was 1.510 centimeters. Also 0.301 and 0.218 represent the averages for the ratio of the height to the length of the arch for children of these ages. ----------- “ Report of some studies upon the arch of the foot in infancy.” Journal of the Boston Society of Medical Sciences [Boston], vol. 3 (1 89 8-99), pp. 209-213.

Toulouse, no. 618, 1905. 130 pp. Thesis (Toulouse University). After a sketch of previous work on the thorax, the author describes the technique of measurement employed by Professor Maurel,. showing cuts of his stethometer and stethographer, and de scribes in detail his own investigation of the thorax with Maurel s methods upon 63 boys between 6 and 16 years old in a private and a public school. Thirteen lads were ruled out as abnormal. The remaining 50 were put into five classes according to ages : 6 to 8. 8 to 10, 10 to 1-, 12 to 14, and 14 to 16 Besides many data on the thorax, including the anteroposterior and trans verse diameters, thoracic perimeter, respiratory type, pulmonary capacity, length of thorax and sternum, etc., the author determined the height, weight, and cutaneous surface. The figures are tabulated and frequently are compared with those obtained by Quetelet of Belgium and Dick of Russia. Many con clusions are drawn by the author. Briefly, he believes that ift the period between 6 and 16 there is a constant proportion between the thorax on the one hand and the height, weight, and body surface, on the other.

To determiné whether the widespread belief in the flatness of the negro foot is founded on fact, the authors made examination of the feet of 88 adult negroes, 34 adult whites, and 40 negro children. They found that among negro children the normal foot preponderates, but flattening of the arch of the foot is much more frequent in the negro than in the white adult.

Author studied development of the pelvis in living individuals, three males and three females, of every year of age between birth and 20 years. Measurements were made of spines, crests, trochanters, and conjugate diameters. Data are shown in full tables and one graph. During the first year a great and regular increase of the pelvis in all diameters takes place. In the following four, years the external conjugate grows but slightly as compared with transverse measure ments. From 6 to 10 the external conjugate has a relatively great growth, and the other measurements a more or less regular increase. From 10 to 11 all female dimensions are larger than male, and during the next four years they increase much more rapidly than in the male. Until the age of 10 to 11 there has been little difference between the sexes. By the. age of 20 the male pelvis has equaled the female in transverse dimensions but not in conjugata.

In seeking an anatomical cause for the greater frequency of hip dislocation among girls than boys the author measured 21 cadavers of infants. He arrived at a corrective figure for the thickness of the genitals in measuring the length of the lower extremities. In 200 boys and 200 girls he found the difference of this length insignificant. Measurement, in 200 subjects, of the https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 118 PHYSICAL GROWTH AND DEVELOPMENT OF TH E CHILD transverse diameter of the trunk at the level of the iliac crest showed no appreciable variation. Height of the pelvis covered with fleshy in 100 subjects of both sexes, showed a negligible difference. Anteroposterior diameter of the pelvis at level of the anterior and superior iliac spines was notably greater in girls than in hoys. Data are presented in tables. 58 Long, E li, and E. W .

Data are original, the work corresponding to that reported by Doctor Rotch in “ The Roentgen Ray in Pediatrics.” Two hundred radiographs of both wrists were taken. The subjects varied in age from infants to young men, hnd in mental capacity from idiots to brilliant high-school students. Figures 1 to 13 and 19 to 44 are X rays and photographs of cases cited. Charts 14 to 18 show the relation of carpal development to height, weight, age, and mind. The author’s conclusions are: (1) The two wrists do not develop synchronously in an individual, neither is carpal development an index of general osseous or of mental development; (2) age, height, and weight increase in general with, advance in carpal development. 59 M andelstam , J .: “ Über die Grösse des gegenseitigen Abstandes der grossen und kleinen Fontanelle bei neugeborenen Kindern ” [Distance between large and small fontanel in newborn children].

Data for this study, which the author feels insufficient for final conclusions, were secured by measurement of various series of skulls and skeletons, includ ing a small number of those of children, from birth to age of maturity. The relations studied in this paper concern the skull, the femur, and the jaw, the first as having a protective relation to the brain and sense organs, the second as representing by its weight the development in volume of the organs of locomotion and support, and the third representing the development of the nutritive system. The data include a table showing the craniocerebral index of a number of children (perhaps 20; inexactly stated), a table showing craniomandibular index of 14 children, and a few other observations on sub jects under 20 years of age. 61 M aurel, E. : “ Étude du thorax chez le nouveau-né ” [Study of the thoraxof the newborn infant].

The author measured the capacity of the skulls of 77 hoys and 77 girls from a few days to about 10 years old, most of them less than a year old. The material was from the Children’s Hospital of Emperor and Empress Frederick and excluded foreign races and pathological conditions. The data are shown in tables, and the mean volumes for given ages are listed. The author describes his methods of dissection and explains how he arrives at the conclusion that the capacity of the cranial cavity is that of the skull minus 6% per cent. That of boys is always larger than that of girls. This difference, about 20 cubic centimeters at birth, is over 100 cubic centimeters by the fourth year. A t-"2% years of age, two-thirds of the total increase in head volume has been attained. Large individual variations often occur, even when sex and age are the same.

This article, after reviewing the literature on the thoracic index, considers first thoracic measurements made upon 506 healthy negroes (212 males and 294 females) from the age of a few days to 86 years. Very few showed predominant | :blood. Age, sex, weight, height, and physique also were noted. The 1? <l13 1^ualsJwere measured standing, with arms hanging naturally at sides, clothed, and at the end of quiet expiration, with an elastic band placed around the thorax at the level of the gladiolo xiphoid articulation. The circumfer ence of the thorax was measured with a steel tape measure, the anteroposterior diameter in the midsagittal plane with IVIartin’s pelvimeter, and the transverse diameter at the widest point of thorax. As defined by Rodes, the thoracic index (unlike that of investigators before Hutchinson) is the ratio of the anteroposterior to the transverse diameter. There was a rapid decrease in the thoracic index of the negroes examined from about birth to puberty and thereafter a more gradual rise. The thorax was more rounded in the female than in the male. In 50 young white women at Missouri University the index was found by the author to be 73.14. In 48 young negro women he found it to be 70.9. Other investigators have determined the index of white-^males to be 73.48, 73.6, 74.6, and 70. The author has determined it for male negroes at 70.7. Therefore the thorax of the negro is flatter than that o f the whites. The author also measured 11 embryos and fetuses irre spective of race, finding that the thoracic index is at first very high then decreases, at first rapidly, and then more slowly.

Data were obtained by measurements of the thoraxes of late fetuses and full-term stillborn children and of living infants on the first, third, fifth, seventh, tenth, and twelfth days after birth. Data on the circumference of the chest immediately before and after the first inspiration were taken from the observations of Linzenmeier. The authors found that the horizontal chest circumference (at the nipples) is markedly increased at the first inspiration. Within 12 hours after birth it enters a period of decrease which continues for two or three days and is followed by increase, the initial circumference being regained in the second week. The anteroposterior and the transverse diameter of the thorax, both at the level of the nipples and at the tenth rib, shows changes comparable with those of the circumferences at these levels. The thoracic index (anteroposterior diameter divided by transverse diameter and multiplied by 100) at the nipples stands at about 86 before birth, rises to an average of 106, and then drops to about 102 in the first 24 hours.

In the Children’s Clinic of Erlangen University, from the spring of 1918 to the summer of 1919, the author took 700 X-ray pictures of children, 250 of whom were normal. Of these, 68 girls and 57 boys, between birth and the age of 13, from the moderate-sized children of the laboring class constituted the mean. In studying age, sex, height, class, etc., in relation to ossification, the author classified his subjects into tall, medium, and short children, accord ing to Pirquet, and into laboring, agricultural, and upper classes. He con cludes that the centers of ossification appear earlier in girls than boys, as regards both age and height; that wealthier children develop more rapidly; that there is no appreciable difference between right and left hands in ossifica tion ; that growth processes are regulated by the endocrines; and that even for normal children no general scheme is valid.

Material for study was a collection of 110 skeletons in the laboratory of Western Reserve University. Of these, 20 belonged to the age period from 15 to 19, inclusive, barring the possibility that one was of the fourteenth year. An extended study showed the essential reliability of epiphyseal union as an indicator of age, especially in the case of the long bones. In the 15 to 20 year period the epiphysis of the distal extremity of the humerus unites first; that of the head last. The age of the greatest epiphyseal activity is the nine teenth year.

This article, one of a highly technical series on the skull, contains 70 pages, 23 figures, and 6 tables on the tension of the cranial wall. Much space is given to the pressure of the cerebrospinal fluid in the subarachnoid spaces. The development of the complicated forms of the skull is to be explained only when pressure of the brain is added to pressure of said fluid and at least in certain places is greater than the latter.

The author found eruption among the Filipinos from one to four years earlier than among Germans and Americans, and among Americans slightly earlier than among Germans ; the females of the races studied were more precocious than males in regard to the eruption of teeth, but this difference was very slight among Filipinos. He found also that the lower teetn erupt before the upper, except the upper premolars ; that there are slight racial differences in the order of eruption ; that the law of alternation in development of the structures of the body decrees that periods of acceleration in the development of one structure shall be synchronous with periods of re tardation in the development of another. 115 ----------- “ The eruption of the teeth as a physiological standard for test ing development.” Pedagogical Seminary [Worcester], vol. 21 (1914), pp. 596-614.

Determining the average or mean number of teeth erupted or erupting at each age, the author found that eruplion begins earlier among Filipinos than in the German and American groups; that the girls of each group* are more precocious than the boys in eruption of teeth. From his data he constructed a table giving the physiological standard of eruption, and the time at which 50 per cent of the teeth are present.

The authors investigated the eruption of teeth of all the children attending the dental department of a hospital for children during a period of about five years. Method of examination and record are explained in detail. Cases ranging from 5 to 12 years were grouped in periods of three months, and a system was devised to show the teeth present in each age group.

After discussing the inadequacy of previous statistics on teeth, the author presents results for children he personally examined. Children of different sexes and ages are considered separately. The numerous tables include fig ures for thousands of children from different parts of Germany. The author found that all permanent teeth erupt earlier with girls than boys ; the canine teeth are much larger in the male than the female and are particularly late in erupting in boys ; in general, the time of cutting permanent teeth is very variable. The fact that teeth are out earlier in Sweden than in Germany, and earlier in the upper than in the lower classes, may be due to the pre dominance of the Germanic race. ------ — “ Zahnverderbnis und Militartauglichkeit ” [Decay of teeth and military fitness].

Data for this investigation were obtained from plaster casts of the dental arches and from measurements of some 350 schoolboys of Utuado, P. R., collected by Franz Boas in 1915. Tables were constructed showing the num ber of deciduous and permanent teeth present among a total of all possible teeth, and these formed the basis for other tables showing the average age and variabilities for the loss of the deciduous and the eruption of the perma nent teeth. These were compared with similar data on Boston boys, from figures by Channing, and showed that the Porto Rican boys appear to erupt their teeth about a year in advance of Boston boys. Further investigation of the data showed a marked functional relation between stature and stage of dental development in both groups of boys.

The discussion covers 28 pages, of which 10 consider ages up to 21 years. At different ages the relation of the width of tnese arteries to height and to heart volume varies greatly. The pulmonary artery is larger than the ascending aorta to the end of puberty: later the relation changes. The heart develops most rapidly in the first and second years The sexual difference is slight up to seven years. To the fifteenth year the growth is greater in the female; thereafter it is greater in the male. From puberty on, the blood pressure in the two great arteries leading from the heart is lower in the female than in the male. Blood pressure in general increases with age till it reaches its height at the prime of life. Pubertal development depends very largely on relatively great increase of blood pressure at this time, when the arterial system is relatively narrow and the heart is growing rapidly, 0 137 Cavaglieri, E .: “ II cuore e l’apparechio circolatorio nei primi dieci anni di v it a ” [The heart and circulatory system in the first ten years of life].

Post-mortem observations of 29 subjects less than 15 years of age led the author to question the findings of Testier and others as to the shape of the heart in childhood. Observations are recorded in detail, but the number is con sidered too small for definite conclusions. 139 DeBuys, L. R ., and E. C.

From study of 623 röntgenograms of 400 normal infant hearts, taken within the first 24 hours after birth and at different periods up to the thirty-ninth month, the authors conclude that up to this time there is no rotation of the heart and that it does not assume a more vertical position. 1 4 0 ----------------------- Further observations upon the shadows of the thymus and the heart.” Southern Medical Journal [Birmingham], vol. 17 (1924), pp. 260-264. ’ ; f ' A report on 450 observations, a part on infants included in the authors’ first study, new observations having been made at 6 months and 1 year, and a part on newborn infants. Eighteen additional reproductions of radiographs confirm the findings of the original study. The authors believe that “ the change in the position of the apex beat of the heart in the first year is appar ently not due to its rotation, but to the slower growth in size o f the heart as compared with the more rapid growth in the size of the thorax.” & https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 130 141 142 143 144 145 146 147 148 P H Y S IC A L G RO W TH AND D EVELOPM EN T OF T H E C H ILD Dietlen, H a n s: “ Die Perkussion der wahren Herzgrenzen ” [Percussion of true heart lim its].

The author summarizes studies of arteries of embryos, infants, older children, and adults made by several writers. In numerous tables he gives averages o f diameters of arteries, thickness of arterial walls in micromillimeters, and circumference of arteries as obtained by those writers. The purpose of his own study was to ascertain changes in arterial walls produced by the growth o f the individual. With this aim in view he studied the arteries of the bodies of 29 children, most of them under 1 year old, and those of 2 adults. In a number of tables he gives the circumferences and thicknesses of the walls of various arteries of each subject and presents his findings on the increase with age in the thickness of the walls and circumferences of the various arteries and aorta. Bibliography. Elsässer: “ Über den Zustand der Fötuskreislaufwege bei neugeborenen Kindern ” [Condition of fetal circulatory passages in newborn chil dren]. Zeitschrift für die Staatsarzneikunde [Erlangen], 21st year (1841), pp. 3-18. The author examined the fetal circulatory system in 144 newborn infants. Of 52 born dead, 48 showed the fetal passages still open, but in 4 the foramen ovale was closed. Of the other 92 infants who died during the first month, 58 showed passages fully open. Hence the time of closing is uncertain. As a rule, ductus Arantii closes first, then ductus Botalli, and, last, foramen ovale. In other words, fetal circulatory passages are usually fully open some time after birth. Therefore, their being open or closed is no indication whether a newborn child found dead has breathed or not. ----------- “ Über den Zustand der Fötuskreislaufwege bei neugeborenen Kindern ” [Condition of fetal circulatory passages in newborn chil dren], Zeitschrift für die Staatsarzneikunde [Erlangen], voi. 63-64 (1852), pp. 247-261. On examining 70 stillborn children the author found ductus Botalli and foramen ovale open in all and ductus Arantii open in all but 1. Among 300 infants that died after birth all passages were open in 80 o f 108 pre maturely born and in 127 of 192 full-term infants. Therefore, as a ruleT the fetal passages mentioned are still open after birth. The time at which they close can not be determined precisely, but it falls within the first six weeks. Gibson, G.

Beiträge zur Kinderheilkunde aus dem Ersten Öffentlichen Kinderkranken-Institute in Wien [Vienna], pt. 1, 1890-91. 194 pp. The first two chapters of this treatise, entitled “ Introduction ” and “ Normal Auscultation,” describe the heart in healthy children and repeat many data collected by other students. The heart in the young child is strong, owing to the relatively wide diameter of the subclavian and carotid. Between the ages of 7 and 12 this diameter diminishes as compared with the mass of the heart. The conclusions drawn by Rillet and Barthez from examination at autopsy of 193 children, aged between 15 months and 14% years, show that the girth of the heart remains relatively the same between 15 months and 5% years ; from, then to puberty it increases. The author considers normal auscultation, rhythm of heart tones, prevalence of systolic tones, influence of respiration, with tables by Steffen on the frequency of the pulse, and by Beneke and Bigot on the volume of the heart and width of the aorta and pulmonalis in children.

In healthy children the relation of transverse diameters of heart and lungs is 1 : 1.9-2 ; in "new born, 1: 1.7. The latter have relatively large hearts. The infant heart is usually a long oval, and its position is slightly tilted, almost never horizontal. It shows, however, a remarkable movability.

After discussing discovery by Galen of the closing of the ductus arteriosus at birth, and the investigation concerning it since- Harvey, the author attempts to test the topographical and anatomical findings of Walkhoff. He dissects four full-term infants that died at birth without breathing, and two that died at age of 4 or 5 days when the tissue would still show conditions at birth, de scribing in detail how the. chests had changed in these two groups. He also inflated the lungs in 15 fetuses, treating some with lime, some with paraffin, till he obtained three good molds of the ductus tube, wherein a sudden bend was clearly to be discerned. He concludes that several factors are con cerned in closing the arterial duct. The newborn infant breathes, the lungs expand, the heart is raised in toto, it turns on its long axis, and its point, turns to the left. The tube is bent ; there is a muscular contraction. All this is made possible by the loose placing of the ductus and the yielding structure. One table and a bibliography are included.

The author made microscopic examinations of the capillaries of the fingers of a number of infants and has illustrated her findings with eight drawings. “ In general,” she states, “ it might be said that from birth the end capil laries begin development from small loops at the periphery of the subcapillary plexus. Until about the third month the development is very rapid. From then on there is not much change.” The article includes a review of the litera ture of similar research. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 132 P H Y S IC A L G RO W TH AND D EVELOPM EN T OF T H E C H ILD 155 Mosler, E ., and M . Kretschner: “ Über den Tonus des kindlichen Herz muskels ” [On the tonicity of the cardiac muscle in the child]. Klinische Wochenschrift [Berlin and Munich], vol. 3 (1924), pp. 2096-2097. ' The author made Valsalva’s experiment on 16 children, 7 of them girls 6 to 14% years old, in order t o . form a judgment of the degree, of persistency of form of the child’s heart And' to compare the data with those 'obtained on adults. All children had healthy lungs and organs^ of circulation. In most of these cases the child’s heart showed very slight resistance to Valsalva s experi ment, as shown by the shadow on the X-ray screen, . The pulse disappeared in all cases in which the Valsalva was carried put in an orderly manner; the blood pressure, which before the experiment was 100 to 120, went down to zero after 3 to 4 pulse beats. There was never a rise in the blood pressure as is the case with adults. The authors conclude that the child’ s heart pos sesses a considerably slighter persistency of form than the adiilt heart, that it, therefore, resembles an insufficient adult heart with decreased tonicity ; that for this reason children in general should be kept away from excessive exer cise, and that in athletics and gymnastics attention should be paid to proper breathing exercises, because children knowing how to breathe properly will not often employ the type of breathing of the Valsalva experiment, and will thus avoid injury to the circulatory system. The X-ray findings for each case are given in a table. 156 Potain, and Vaque 2 : “ Du cœur chez les jeunes sujets et de la prétendue hypertrophie de croissance ” [The heart in young people and its alleged hypertrophy due to growth]. Semaine médicale [Paris], vol. 15 (1895), pp. 413-415. The authors deny that growth causes a cardiac hypertrophy such as was described in Semaine médicale in 1885 by G. Sée, and in 1894. by S. Saache. They examined 43 boys 5 to 13 years old àt the Hospital^of St. Louis ; 27 boys 14 to 20 years old at the École d’Alembert, in a very fine state of health; 12 soldiers from 20 to 24 years old at Fort de Mogent ; and 20more soldiers between 20 and 29 at the École de la Faisanderie. Pathological hearts were excluded. The authors regard percussion as the only accurate means of deter mining the volume of the ¡heart. They found that the heart grows gradually to the eleventh or twelfth year, then very rapidly for some years, and more moderately between the seventeenth arid twenty-third years. The1 volume of the heart shows no relation to weight but a decided relation to height and thoracic perimeter, as is shown in a graph. No relation appears to exist among frequency of pulse, arterial tension, and physiological development of the heart. Another graph shows how muscular exercise in military service in creases the volume of the heart. Dividing soldiers into groups according to amount of gymnastics, the authorsascertained for the volume of the heart 91 cubic centimeters in the least athletic group, 98 cubic centimeters in the next, and 101 cubic centimeters in the most athletic group. 157 Preisicli, K o rn e l: “ Herzvolumen im Säuglings- und Kindesalter” [Vol ume of the heart in infancy and childhood].

Many phases of the heart are treated, such as mobility, relation to lungs and thymus, and shifting of position according to pose of body. 159 Sawyer, J. E. H . : “A note upon the position of the apex beat in children.” British Journal of Children's Diseases [London], vol. 6 (1909), pp. 535-540. The author examined 500 normal children of varying types of development from less than 1 year to 15 years of age to determine the position of the apex beat in relation to the. left mammary line in the fifth intercostal space. All the children were examined in the erect position, the mammary line being determined by the position of the left nipple. Charts show the usual position of the apex beat in each year of childhood. The apex beat was found outside this line in 104 cases, at the line in 310 cases, and inside in 86 cases. The author concludes that the apex beat is normally outside the line up to the third year and at the line from the third to the tenth year ; after this it gradrally assumes the adult position. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis G RO W TH AND D EVELOPM EN T OP PARTS OF BODY 133 160 von Starck, W . : “ Die Lage des Spitzenstosses und die Percussion des Herzens im Kindesalter ” [Position of apex beat and percussion of heart in childhood].

Berliner Klinische Wochenschrift [Berlin], vol. 31 (1894), pp. 498-500. The author discusses the closure of the ductus arteriosus (falsely called ductus Botalli), the great vessel that leads from the pulmonalis to the aorta in the fetus and is dropped from the circulation after birth. He dis sected this duct in the fetus, and also experimented on it with injections of gypsum, gelatine, etc. He explains how the duct is closed when breathing commences by the lowering of pressure in the right heart and in the arteria pulmonalis. In the fetus before the thirtieth week the closure is not suffi cient and all the vessels in the thorax are filled with blood. But normally the closing of the duct is momentary and mechanical, as is proved by the clear heart tones of the newborn. ■î Térrien, Eugène: “ Situation et déplacements physiologiques de la pointe du cœur chez les enfants de 5 à 15 a n s” [Situation and physiological displacements of the apex of the heart in children from 5 to 15 years of age].

The temperature varied between 30° C. and 38° C. Thè tests were begun three hours after meals, and the total num ber of leucocytes were counted before and after the tests. The results are pre sented in a long table. In 80 per cent of the cases the direct sunlight caused a general leUcocytosis in the peripheral blood. The lymphocytes increased much more, relatively, than other kinds of leucocytes ; there was a relative decrease of neutrophiles. The author believes the lymphocytosis partly accounts for the favorable influence of heliotherapy upon tuberculosis.

Bakwin, H arry, and Helen R iv k in : “ The estimation of the volume of blood in normal infants and in infants with severe malnutrition.” Am. J. Dis. Child. [Chicago], voi.-27 (1924), pp. 340-351. Using a micromodification of the dye method of Keith, Rowntree, and Geraghty, by which, blood volume can be determined with 4 cubic centimeters of blood, the authors made determinations of the blood, plasma, and corpuscular volume in a group of 30 infants under 8 months of age, normal for the pur poses of this study, and in* a second group of infants with severe malnutrition. Repeated determinations were made in 16 instances. Tables show total volume and volume per kilogram of body weight, grams hemoglobin per 100 cubic centimeters and serum protein per cent for both series of infants, and charts the volume of blood, plasfna, And red cells per kilogram of body weight in rela tion to age in normal infants. The authors found that at birth the corpuscular volume is relatively high, falling rapidly so that the absolute volume of red cells is less at 8 weeks’ of age than at birth. The average value of blood volume is 101 cubic centimeters per kilogram of body weight; of plasma volume. 61 cubic centimeters. The blood volume per unit of body surface in infants is much smaller than in adults. References. Sang, Iv a r : “ Über Lipämie I ” [On lipemia].

Jahrb. f. Kinderli. (B erlin), vol. 52 (1900), pp. 215-241, 333-359. 684-720. The author studies the percentage in the blood of polynuclear leucocytes lymphocytes, transitional forms, large mononuclear leucocytes, and eosinophilic cells. His subjects he chose from the healthiest of the poor people that visited his hospital. He divides them into the following groups : 5 newborn, whom he examined daily during the first 12 days ; 5 infants from 1 to 6 months old and o from 6 to 12 months ; 5 in each year from the second to the fifteenth ; and 5 from la to 20 years. Preceding investigations are discussed for purposes of comparison. The results of the present study are as follows : Hemoglobin content is higher in the newborn than later. Polynuclear leucocytes show a high percentage (73.45) during the first 24 hours. They then sink to 36.12 by the ninth day, and so remain a half year. From the fifth year to old age they amount to 51.86 to 69.22 per cent. Lymphocytes have a low value (16.05 per cent) in the first 24 hours and a value of 45.6 per cent by the twelfth dav They vary between 19.33 and 33.25 per cent from fifth year to. old age. The transitional forms show 18.66 per cent in the first week and fluctuate "between 6.75 and 9.47 per cent from the age of 6 months to the end of life. Large mononuclear leucocytes seldom exceed 1 per cent at any period. Eosinophilic cells are not affected by age. 195 Cherry, Thos. H ., and Ed. G. Langrock: “ The relation of hemolysis in the transfusion of babies with the mothers as donors.” J A M. A [Chicago], vol. 66 (1916), pp. 626-627. In 34 tests of agglutination with mothers’ and their newborn infants’ blood no agglutination was noted by the ocular method in any case. Hence these aerologists conclude that all mothers can be used as donors for their infants if there is no contraindication in the .mother’s condition. 196 Courtney, Angelia M ., and Helen L.

The authors made 79 determinations of blood solids and 81 of blood chlorid on 67 children, most of them under 2 years of age. Thirteen were wellnourished, normal children from 2 months to 6 years of age. A table of data on the normal children shows age, percentage of water in blood, total solids (percentage by weight) and chlorid in 1 cubic centimeter of plasma, computed as grams of sodium chlorid. The concentration of chlorid in the plasma was about the same as that of normal adults ; the average for total solids in the blood was about 5 per cent lower than for adults.

The author describes in great detail his study of the blood of 146 healthy children between 2 weeks and 6 years of age, including for comparison studies o f the blood of 124 children suffering from various maladies. Tables show the differences in hemoglobin value between heel and ear blood ; between blood obtained by incision with a sharp cataract knife and with a blunter instrument * between blood obtained by a superficial and by a deep incision. Findings are compared with those of other investigators, with references. The great diver gencies in reported results are attributed to technical and physiological errors and to differences in racial characteristics. The author’s examination of 85 healthy children from 2 weeks to 2 years of age showed a rapid initial fall in the hemoglobin curve, which reached a low level about the second or third month, remained level for the first year and rose again during the second year. The cell volume; except in the first few months, was found to be about the s%me as that of healthy adult women. 198 Duperie, P. L.

To obtain the mother blood and the fetal blood, the author in 14 cases took blood from the uterus and the umbilical cord near placenta, immediately alter delivery. He found that the two samples of blood agglutimzed in very dif ferent fashions, as if they came from quite different organisms. He gives a table of the action of the mother and child serum. The mother and fetal blood are therefore different in their percentage of agglutinins and lysms. Often the blood of a mother contains agglutinins of which her child has no trace Therefore the fetus selects only certain albuminous substances from the mother body. Sometimes agglutinins are found in fetal and not in parental blood. The author discusses work on agglutinization done by other investi gators. 223 H allez, G.

It was found that the grouping as present m adults is rarely present in blood from the umbilical cord ; that isoagglutination, rarely present at birth, is always present after two years ; that the grouping is established in the corpuscles before it is in the serum; that the early grouping in the corpuscles is liable to change by the acquisition of new receptors (; that grouping, once established, does not change; that isoagglutinins are present in mother's milk.grouped as in her blood, but these agglutinins are probably not transmitted to the nursing infant; tb,at_it_is not safe to transfuse an infant from its mother without making the preliminary tests. 225 H aselhorst, G., and A .

The author studied digestive leucocytosis in infancy at the Charité, Berlin. He is interested not only in the whole number of white blood corpuscles but also in the relation of the various kinds. The infant blood is taken from the finger or toe before and after the meal, which contains 1.1 to 4.6 grams of animal albumin. Descriptions are given of 14 tests on 12 healthy infants, also of tests on sick infants and adults, followed by a discussion of other literature on this subject. The •author concludes that digestive leucocytosis can not be considered a constant phenomenon in infancy and certainly has no diagnostic value. In the healthy person beyond the nursling age there is usually leucocytosis after a meal containing animal albumin and following a period of fasting. The leucocytosis consists chiefly in an increase of poly nuclear cells. Digestive leucocytosis is not an essential element in absorption, but only an attendant circumstance. —— “ Die Leukocyten beim gesunden und kranken Saugling” [Leu cocytes in the healthy and sick infant].

The author describes his technique fully. Of 197 cases in which the blood was collected from the placental end of the umbilical cord, all could be placed in the four accepted groups. Of these, 78.7 per cent were confirmed by noting the agglutinating action of infant serum on cells of known groups. The percentage of newborn infants, here reported as having their group established, is much higher than has previously been reported. “ The results seem to depend o n . a technique which permits the recognition of weak agglutinins. Isoagglutinins have been demonstrated in the blood of a seven-months’ fetus. The demonstration of strong isohemolysins in the serum of newborn infants indicates the advisability of making proper test for compatibility before selecting a donor for transfusion in infants. ----------- “ Isohemolysins in human blood, with especial reference to the blood of the newborn.” Am.

The technique of this investigation is described, and possible errors of technique are noted. Although the properties of isoagglutinins and isobemolysins are closely related, and isohemolysins never occur independently o f isoaggliitinins, much less work has been done on isohemolysins than on isoagglutinins. In this study 121 specimens of blood from the newborn and 144 specimens of adult blood were examined for isohemolysins. They were found in 27.3 per cent of infants in blood of certain groups and in 88.5 per cent of adult specimens of the same group. Infants’ serum was generally weaker and isohemolysin “ a ” predominated. Jones, E.

He found the specific gravity highest at birth, about 1,066 in both sexes. Within the first two weeks it began to fall, continuing to fall until the second year. The average in this period was for males, 1,048; for females, 1,050. From the age of 6 to 12 the average for males was 1,050.5; for females, 1,052, From the age of 12 it continued to rise to the period 35 to 45, more rapidly in the male than in the female.

The alkali reserve of plasma, and the distribution of calcium and the com pounds of phosphoric acid in the blood, were studied in 34 normal children, from 4 weeks to 14 years of age. The corpuscles were found to be richer in all types of phosphoric acid than the plasma. In general, calcium and phosphorus values for boys averaged slightly higher than those for girls. The average calcium content of corpuscles was found to be slightly less than that o f the plasma, the values in milligrams per 100 cubic centimeters being as follow s: Whole blood, 9.4; corpuscles, 8.7; plasma, 10.

The author investigated the lime content of the blood of 62 children up to 14 years old, including 12 newborn, in a children’s clinic in St. Petersburg. She made 200 tests by Wright’s method, with varying factors of age, diet, rickets, and spasmophilia. Her results in some cases coincided with Neurath s and in others did not. The general conclusion is that the blood of normal children endeavors to maintain a lime content corresponding to an ammonium oxalate solution 1:1800, irrespective of age and diet. Newborn infants show a smaller lime content. Rachitis made no difference, spasmophilia caused a smaller content. The article contains six tables. 244 K eating, John M ., and W illia m A .

It appears , in two great curves between birth and the third month and between the eighth and the nineteenth month. Eighteen tests proved a close relationship between the agglutinin content, of the blood of the mother and child. Nine series of tests on the blood of the mother before delivery, on the blood of umbilical cord, and on the blood of the newborn showed that in all* probability normal agglutination of the infant is inherited from the mother. Of 20 tests on infants between 8 days and 14 months of age before and after inoculation with colon bacilli only 5 presented large agglutinin values. Kramer, B., F. Tisdall, and J.

These investigators attack the assertions, made that the blood calcium con centration is variable in thè normal child. They state that diet, exercise, etc., exert little influence on the calciums content of the serum. A normal child’s blood contains a higher calcium concentration than an adult’s.

The normal C for nurslings over 4 weeks is between 1.3 and 1.52; it rises with the age of the nursling. Great uni formity was found in healthy infants nourished on a milk mixture plus 5 per cent sugar, when the sinus puncture was made two hours after the second meal. A low C, i. e., an acidotic state, was ascertained in newborn infants, in the umbilical-cord blood and in premature infants, and always before death. Fat lowered the alkalinity of the blood more than carbohydrates did.

Water in infants’ blood is 78.93 per cent, in mothers’ blood 80.16 per cent. Fibrin content is much less than that of mothers. Hemoglobin is about the same in both but increases in the blood of the newborn. Sex and weight do not essentially affect constitution of blood. Blood at birth coagulates easily but slowly.

The author writes at length on former investigations by other Students and on his own extensive studies of physiological and pathological cases. His article contains 18 tables and a bibliography, As regards children, he decides that the serum of newborn infants rarely shows isogglutination, whereas their erythrocytes are as agglutinable as those of older children. The agglutinins https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GROWTH AND DEVELOPMENT OF PARTS OF BODY 147 seem to appear in the first months of life. It is not yet certain whether isoagglutinin formation comes from the colostrum or from mother’s milk through simple absorption by the child’s organism, or from some other source. 253 Leichtenstern, 0 . : Untersuchungen über den Haemoglobulingehalt des Blutes, in gesunden and. kranken Zuständen [Investigations into the Hemoglobulin Content of the Blood in Health and Sickness]. F. C W Vogel, Leipzig, 1878. 106 pp. Ninety-one healthy persons from 36 hours to 20 years old, as well as 100 over that age, were examined. The blood of healthy newborn infants is richer in hemoglobin than that o f any other period. At the age of 10 to 12 weehs the hemoglobin content is similar to that of adults. The minimum is 1eached between the age of 6 months and 5 years. There is a gradual increase of hemogiobin content from 6 to 15 years of age. The increase is more decided after the age of 15. In childhood up to 10 years there is 7 per cent more hemoglobin in the blood of boys than of girls.

A report o f 95 examinations of the blood of children from 1 month to 16 years of age by methods carefully described. Six leucocytic curves are given for infants from 1 mon h to 1 year of age. The author found the leucocytic count o f infants variable, changing even in the same infant from minute to minute. Each infant, however, has a curve peculiar to itself, which repeated examinations even at long intervals, establish and confirm. The general character of this curve is variable. In the normal infant it varies with the amount of milk invested, an increase of white corpuscle^ being evident after a small meal, a diminution after a large meal, the amount of milk at which the change takes place varying from 50 to 100 grams and differing for breast-fed artificially-fed infants. Results with children from 2 to 16 years were difficult to reduce to a general law. 255 L ief mann.

It having been proved that the blood of every healthy person contains uric acid, the author undertook to test the blood of children with the AutenriéthKonigs berger calorimeter. She extracted 5 cubic centimeters of blood from the heel. One table gives the uric acid in 13 normal cases from 9 weeks to 21 years of age. The value for nurslings is 1.3 to 1.7 milligrams in 100 cubic centimeters of blood. The value rises "with age to 2 to 4 milligrams (Steinitz) in- adults. An abnormally high uric-acid value accompanies a purin diet and many diseases— not, however, the exudative diathesis. 256 Ligh t, Gertrude 17. : “ The blood in infancy and childhood.” New York M.

The author gives full references and summaries from the data of eight investigators who found that at birth the red blood cells number 5,742,080 ; the white blood cells, 15 000hemoglobin, 125 to 130 per cent. The blood assumes adult proportions about the twelfth year. Infants’ blood tends to resume embryonal characteristics when clinical balance is disturbed, these changes being out of proportion to the cause. 257 Lindberg, G ustaf: “ Über den Blutzuckerspiegel des Säuglings im Hun g e r ” [The picture of sugar in the blood of fasting infants]. Ztschr. f. Kinderh. Originalien [Berlin], vol. 15 (1 91 6-17), pp. 71-83. Lindberg used Bang’s micromethod in his blood tests of 14 breast-fed babies from 3 to 9 months’ old, some of whom had begun mixed feeding. Eight of them were entirely healthy, and six were healthy except for exudative diathesis He took their blood in the evening three hours after they had eaten and just before their dinner ; thereafter, for 60 hours, they received only saccharin and water. He noted weight and the samples of blood during this fast and after they returned to normal fare. Results are put in two curves and three tables. In weight , the children lost on an average 6.5 per cent. They seemed to feel no discomfort from the fast. Sugar values in the healthy children were on an average 0.074 per cent after a fast of 24 hours ; 0.073 per cent after 36 hours ; 0.074 per cent after 48 hours; and 0.074 per cent after 60 hours. The exuda tive diathesis caused slightly lower values, except that five cases in the eruption stage showed hyperglycemia. According to these results healthy infants on a hunger diet have about the same amount of sugar in the blood as adults. 258 Lippman, H ym a n Sh alit: “ A morphologic and quantitative study of the blood corpuscles in the new-born period.” Am. J. Dis Child. [Chicago], vol. 27 (1924), pp. 473-526. The greater part of the previous literature on the morphology of the blood of the newborn is presented in condensed, outline form, with brief discussion. The author’s own study was made on 71 newborn infants (31 girls and 40 boys). Examinations of blood from the heel were made as near birth as possible ; at approximate six-hour intervals up to and including 36 hours ; at 48 hours, and at 5 days. Counts were taken of red blood cells, leucocytes, and platelets. Differential studies included the examination of 500 cells in each blood smear. The statistical methods employed are fully discussed, and original data presented in 17 tables and 36 figures. The author finds that the https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 148 PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD morphology of the blood at birth approximates that of the last part of fetal life, and the picture presented is far different from that seen at 6 hours, and again at 12 hours. The observations reported support the view that the neonatal changes are due to the increased stimulation of the blood-forming organs. References. { 259 Lucas, W m .

Believing that a constant relation exists between body weight and the con centration of blood, the author determined the water content of blood by measuring the dry residue. The blood was taken three hours after meals. The average value of water in the blood of nine newborn infants from 1 hour to 30 days old was found to be 77.7 per cent, as compared with 78.14 per cent for the adult man and 79.7 per cent for the adult woman; it was also evident that a close relation exists between body weight and blood concentration and that in the initial loss variations of the water content, are involved. From further tests on nine infants over a month old, the water content in the blood was found to be 81.9 per cent for breast-fed children and 82.2 per cent for . artificially-fed children. Tests on 16 children from 1% to 11 years gave a percentage of 80.62.

With the aid of the Engels-Lowy method (titration with N/75 solution of tartaric acid) the author studied the effect of age and food on the reaction of blood in infants. He studied 39 infants ranging in ages from 8 days to 1 year. He found that the alkalinity of the blood was slightly lower in infants than in adults; the younger the infant the greater the' difference. Breast-fed children show a greater alkaline reaction than those fed artificially. Feeding with diastatic polysaccharides raises the alkalinity. In hunger the latter goes down. The decrease of alkalinity is particularly great on a diet rich in fats. M cC lanahan, H . M ., and A . A .

The blood o f the infant was found to vary from that of the adult in the high proportion of the lymphocytes. A second count on 14 infants showed a con siderable variation from the first.

Data for this study were obtained by examination of the blood of 21 normal infants from birth up to two weeks of age. Tables show the phosphoricacid compounds in the blood of these infants and averages and variations in the phosphoric-acid compounds in the blood of infants and of adults. Very little difference was noted in the sexes. In infants gaining weight the phosphoric-acid values were higher than the average in the plasma and some what lower in the corpuscles, whereas in those losing weight the reverse was the case. The corpuscle values as a whole are remarkably similar in the infant and the adult. In the plasma the organic phosphorus is regularly much higher in the infant than in the adult.

In the Woman’s Clinic at Greifswald Martin conducted experiments on agglutination and isoagglutination. He tested the blood of mothers before, during, and after birth, and of young infants, examining the reaction of the mother’s and the infant’s blood on each other and on his own corpuscles. He found that illness produced no effect, and by comparing the variations that occur in like experiments with the serum and corpuscles of healthy men that pregnancy and birth act like purely physiological functions. He believes that the Marx-Ehrenrootfi method is not sufficiently reliable for forensic prac tice and that Uhlenruth’s method is safer. Three tables give the details of his work.

In both cases variations are very slight. Two other tables prove independence of calcium content of diet and its great constancy. The normal value in the adult is not much higher— 12.2. It seems that the value in the infant below 6 months is a little higher than later. Bibliography.

Thirty-seven samples were taken at time of delivery and four within two hours after delivery. In 10 cases counts were made on the second, eighth, and fourteenth days. The red blood count for the 41 cases, taken within two hours of delivery averaged 7,630,000; the average of the 10 cases taken on second, eighth, and fourteenth days, was 6,260,000. Study of available data on hemoglobin content and erythrocyte count showed that, in childhood, the curves are not parallel, and that the norm employed in determin ing the color index of adults does not apply in determining the color index of children under 10 years of age.

A long table gives full data on the blood-sugar content of 25 children with 30, 50, and 20 grams of dextrose. The concentration of dextrose at time of entering the blood and^not the absolute amount in the alimentary canal is significant for liyperglyiemia. M itchell, A .

Several illustrative case histories are given in detail. The author found that bottle-fed infants do not constantly show digestive leucocytosis. The majority show a smaller number of leucocytes in the superficial blood after taking food than before, the decrease being greatest from one to two and a half hours after food. When a rise does occur, it is most frequently soon after feeding, and a decline begins in a half hour. Crying, struggling, and chilling of the part from which the blood is extracted increase the count. References.

In seven experiments he found nothing abnormal in premature infanls, and in seven further experiments no difference between arterial and venous blood. Six experiments on an accentuated carbohydrate diet showed hyper glycemia, and four on a hunger diet showed hypoglycemia. Psychical disturb ances showed no influence. Thirty-eight experiments on sickly children proved that though fever and alimentary intoxication cause a tendency to hyper glycemia yet in general disease produces little effect on the percentage of sugar in the blood.

For the most part he used Hammerschlag's method, but in a small series of 23 children he used both Hammerschlag’s and the pyknometer method. One table gives minimal, medium, and maximal values; another compares thickness of the blood with the hemo globin content. Blood density is highest in the newborn. It varies directly with weight, varies also with time of day and muscular action, and is positvely correlated with hemoglobin. Moore, Fred: “Acetone bodies in the blood of children.” Am. J. Bis.

He took blood from the ear or great toe o f infants, before and after meals, at half-hour intervals. From a series of experiments on two to four infants in each case he studied leucocytosis in the healthy breast-fed child, the healthy artificially-fed child, and the breast-fed child who was being weaned to cow’s milk. In normal cases he discovered not a leucocytosis but leucopenia, beginning during the nursing and at its maximum 1 to 2% hours afterwards. Then the leucocytes begin to increase and three to four hours after the meal have attained the normal number. On the other hand, when a new kind of albumin is introduced into the system, leucocytosis accompanies digestion. The results appear in tables.

Twenty of the children had a healthy, fresh color and 10 were pale. The tests were made by the CO method as used by Zuntz and Plesch. In the 20 healthy children the average specific gravity was 1.0435, less than that of adults; the amount of blood was 6.92 per cent of body weight, greater than that of adults; the hemoglobin (determined by method of Tallquist, Sahli, and Fleiscbl-Miescher) was 80 per cent of body weight, greater than in adults ; and the oxygen capacity was 15.6 volume per cent, less than in adults. The 10 pale children were free from kidney and other grave complaint. The specific gravity was 1.0410, the amount o f blood 7.12 per cent of body weight, the hemoglobin 79 per cent, and the oxygen 15.3 per cen t; that is, practically the same as in the healthy children.

The author gives the results of his studies of the blood and heart of six pale children between 6 and 12 years old and compares therewith similar in vestigations upon healthy children. The two sets of results showed little difference. The six pale children were not anemic in the ordinary acceptance of the term. Aside from the appearance of the children and the percentage of hemoglobin he found two distinct groups according to relations between oxygen capacity of the blood and oxygen consumption on the one hand and on the other hand the minute-volume and the speed of the flow of blood. 286 287 288 M u ggia, A ld o : “ Sul contenuto di glucosio nel sangue della prima infanzia ” [On the sugar content of the blood in infancy]. Rivista di clinica, pediatrica [Florence], vol. 22 (1924), pp. 1-11. In order to determine the sugar content of the blood of infants, the author analyzed samples of placental blood in four cases; also the blood of 22 normal children ranging in age from 6 days to 2 years, and of 8 sick children from 1 month to 1 year old, using the micromethod of Fontes and Thivolle, with blood taken 3% hours after the child had been fed. The placental blood con tained on an average 0.102 per cent of glucose: in well children under 1 year old the glucose content varied from 0.105 to 0.155 per cent, and during the second year of life from 0.081 to 0.126 per cent.

Ztschr. f. Kinderh. [Berlin], vol. 11 (1914), pp. 92-110. The author determined refractometrically the protein content of the blood of more than 200 children from 1 month to 12 years of age, healthy children and tuberculous. The blood was taken when subjects were lying quiet in bed. Findings are put in two long tables giving age, albumin content in normal and tuberculous cases, etc. The content is 5.3 to 6.8 for the first three months and 5.5 to 7 for the third to the eighth month. The change to the higher value of adults comes about the tenth month. Bibliography.

Ztschr. f. Kinderh. [Berlin], vol. 1 (191 0-11), pp. 3-42. The author is much interested in Wright’s method of _ determining the oxalate-precipitable calcium combinations in the blood of children. He made control tests with other methods and found that the two series of results tally. His experiments were on *4 healthy nurslings and 12 sick children from 1% to 9 years; on the effect of different diets on 16 children from 15 days to 10 months o ld ; on the effect of lime upon 10 children; and also on various patho logical cases. He concluded that in normal human beings the nursling period sbows relatively high values in lime and that they fall with increase of age. Breast-fed children show in their blood a higher content in oxalate-precipitable lime salts than artificially-fed children. More lime in the food only occasionally produces an excess of lime in the blood.

She used Frank’s needle in taking the blood, determined the hemoglobin with. Fleischl’s hemometer as improved by Miescher, and often, in addition, used Gower’s hemoglobinometer. The number of red corpuscles was determined by the apparatus of Thoma£eiss, and the white corpusc’ es were determined by the apparatus o f Thoma. The results obtained are shown in one table for the first three days, in another table for the fourth to the thirtieth day, and in other tables for 2 to 18 months, 2 to 4 years, 4 to 8 years, and 16 to 18 years. The figures are compared with those of other investigators. The author found a higher content in the well to do and a lower in sick children, but no difference caused by sex. The content of hemoglobin and of red corpuscles is highest in the newborn and lowest in the first year and rises to the sixteenth ye°r. That of the white corpuscles is highest in the newborn and sinks to the sixteenth year. Bibliography. Pettibone, C. J. V ., and F. W .

Pfaundler believes that the most promising way to study the blood physically and chemically is through the determination of its alkalinity, which is related to the blood contept in hydroxyl ions. He uses Farka’s method as modified by Hober, whereby the electromotive power is measured by the compensation method after charging the chain by a very sensitive galvanometer. It takes less time and is better than the titration method. Blood was taken from a vein or from a heart puncture directly after death, the two methods giving almost the same results; 100 measurements were made on 40 children. The con centration of the hydroxyl ions in the blood serum varied between 0.2 by 10_T and 3.4 by 1()-7 grams equivalent per liter. Values increased after first year on to maturity. -------— “ Über die actuelle Reaction des kindlichen Blutes ” [Actual re action of child’s blood]. Arch. f. Kinderh.

Blood was taken from the latter while fasting and in bed. Ages ranged from 2 days to 13 years. In 6 cases there was an acid reaction, in 14 an alkaline reaction, in 8 an almost neutral reaction. High alkalinity is rare in the infant ; neutral reaction is rare in the older child.

In each ease he examined the peripheral blood and made a puncture in the tibia for the hematopoietic examination. He gives- his findings in two tables; in one the data on the analysis of the peripheral blood for each infant; hi the second table the contents of the bone marrow in each case. The blood of the newborn is abnormally rich in cellular elements and in hemoglobyi ; and even in the first few days it contains some erythrobla’sts. In- the marrow at the time of birth immature red corpuscles are more numerous than the white ones; a few davs later the proportion is reversed. The more intense proliferation of the white medullary elements coincides chronologically with the diminution of the poly nuclear s in the blood There exists, in general, an inverse relation betwecm ° “ mber the fully formed blood corpuscles, white or red, in the blood and the number o f the immature elements in the marrow.

On the basis of previous tests and those described in this article, the author feels convinced that all constituent parts of milk except water, but especially sugar and salts, can call forth fever and leucocytosis, and that this is not due to bacteria or catarrhal condition. With human milk as well as cow’s milk there appear substances that can in certain circumstances work chemotactica lly ; appearing in normal digestion, they lose their toxic effect in circulation unless too concentrated, as in case of 3 per cent sodium chlorid dose per os. or unless given parenterally. Since albumin and fat play but a small part in this connection, the author’s experiments involve ingredients of whey, milk sugar, and salts, in weak and strong doses, by mouth and subcutaneously, ■but not intravenously, given to three healthy babies and many more dyspeptic ones. Results are put in tables and curves.

At outset he describes his methods o f determining specific gravity of bipod 9 times and of serum 5 times, of determining fibrin content of blood 9 times, content of insoluble salts in blood 6 times and in serum 4 times, chlorin content in blood 6 times and in serum 4 times, and his methods in 4 potassium and sodium deter minations and 10 spectrophotometric hemoglobin determinations. The average specific gravity of the blood of the newborn is 1.0592, of adults 1.0607. Average hemoglobin is 76.8 for infants, 100 for adults. Fibrin content of infants stands in relation to mother’s blood as 2 :7 . Infant blood is richer in salt and in sodium but poorer in potassium than is adult blood. Sex and weight appear to have no effect on the quantitative composition of blood of the infant at birth. Tables are given.

He determined dry residue, ash, albumen, and specific gravity of serum in a large series of cases. Results are tabulated and discussed. ----------- “ Neuere Beiträge zur Hämatologie der Neugeborenen mit be sonderer Rücksicht auf die Abnabelungszeit” [More recent contribu tions to the hematology of newborn infants with special reference to the time of cutting the navel cord].

The author’s own observations are 500 in number upon 27 infants, of whom 18 had the cord cut 10 minutes after birth and 9 at birth. At birth the nurse held the cord and the doctor took a drop of blood from the great t o e ; he took another drop when the cord was cut. On succeeding days of sojourn in the hospital blood tests were made and also, determinations of weight, temperature, urine, chlorides, urates, and specific gravity of the blood. The very numerous tables contain data on the red corpuscles of the blood, according to immediate or late cutting of cord and age, on daily amount of urine, percentage of urea, etc. The author believes that the infant gains in weight through gain of blood during birth and through retention of umbilical cord some minutes after birth, but that this excess of blood is lost during the first three or four days. -------- “ Neuere Beiträge zur Haematologie der Neugeborenen ” [New contributions to the hematology of newborn infants]. Jahrb. f. Kinderh. [Berlin], vol. 54 (1901), pp. 1-23, 172-212. The author made 834 tests of the specific gravity of the blood of 58 infants; 25 he did not consider in this study because they were not perfectly healthy. He also made 259 observations for hemoglobin upon 20 infants and 63 obser vations for the number of red corpuscles. All this experimentation covered the first 10 days of extrauterine life. The direct or pyknometric method and the indirect method are described, of which the author prefers the former. The prick was made in the great toe always in the same circumstances. Full notations were kept of the infant’s condition. Whereas the specific gravity ol the blood in the adult and older child remains approximately the same, that o f the newborn varies for the individual and by day and by hour. The limits for the first 10 days are 1.0813 and 1.0590. There is a decrease of about 0.001 per day and 0.01 from birth until the tenth day. The high specific gravity at birth the author ascribes to initial difficulties of circulation and to rapid cooling. The specific gravity is higher by day than by night, higher in sturdy than weak infants, and in those whose umbilical cord is cut late. Sex and order of birth seem to have no influence.

Zeitschrift für Heilkunde [Berlin], vol. 11 (1890), pp. 17-88. The author discusses in detail the methods and results of his investigations on the red corpuscles, white cells, and hemoglobin in the blood of young Infants. He obtained the blood, usually twice a day, by pricking the great toe with a needle and used Thoma-Zeiss’s apparatus in counting. He presents comprehensive tables and in many cases curves of his tests on about a dozen infants. The red and white corpuscles and hemoglobin are all greater in quantity during the first three or four days of life and decrease with irregular fluctuations. 0 https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 158 321 322 323 324 325 326 327 P H Y SIC A L G RO W TH A M ) D EVELOPM EN T OP T H E CH ILD Schiff, Ernst, and E.

Jahrb. f. Kinderh. [Berlin], vol. 93 (1920), pp. 151-159. After discussing Ivor Bang’s two methods of determining blood lipoids the author lists a number of results he obtained from his own investigations concerning the blood content in neutral, fat, Cholesterin, cholesterinester, and phosphates and fatty acids of infants and older children. The tests were made in the morning after a fast of 10 hours. There was great variation among different individuals and slight variation among various tests on the same; subject. From comparison of above figures obtained from infants, older children, sick children, and children with eczema the author concludes that there is probably a relation between the ester content of blood and resistance to disease. ■ -----------and Cornelia de L a n g e : “ Verdauungsleukocytöse und Verdauungs leukopenie bei Kindern ” [Leueocytosis and leucopenia in children during digestion]. Ztschr. f. Kinderh. [Berlin], vol. 33 (1922), pp. 169-183. To study action of leucocytes during digestion in healthy childhood the authors studied the effect of fasting on 9 subjects, cow’s milk on 11 infants, mother’ s milk on 7 infants, cow’s milk on 12 children between 1% and 8 years, pancreatin solution on 4, and effect of lying and standing on 6. Data are shown in five curves and many tables. Among the conclusions the authors state that Widal’s method of testing function of liver by hemoclastic reaction is not practicable in infants and young children. Number of leucocytes in fasting children is very varied, even in the same child. There is also great variation during digestion, which may be due to difference in time of day, to excitement, exertion, static and chemical influences, etc. Schloss, 0 .

In making the dif ferential white counts the results of the cover slip and slide smears tallied Well, Repeated counts were made on each child. The technique is described. The conclusion was that there is no physiological eosinophilia in childhood; 5 per cent is the upper limit of normal. There is considerable fluctuation in the eosinophile percentage. — - and H elen H a rrin g to n : “ Comparison of the carbon dioxid tension of the alveolar air and the hydrogen-ion concentration of the urine with the bicarbonate of the blood plasma.” Am.

The author emphasizes that the umbilical cord should not be cut until the infant has received the maximum of blood. He refers to writings on the subject by himself and others and describes his tests on five infant cadavers in three of which, where cord was cut after several minutes, the total amount of blood equaled one-ninth of body weight, and in two, where cord was cut im mediately, blood equaled only one-fifteenth of total weight. 329 Schulz, P au l: “ Ein Beitrag zur Frage der Verdauungslipämie ” [A con tribution to the question of digestive lipemia]. Ztschr. f. Kinderh. Originalien [Berlin], vol. 4 (1912), pp. 63-91. To determine lipemia the author uses Schelble’s method of classifying the blood serum as very slightly cloudy, cloudy, very cloudy, and expressively cloudy. To do this he draws a few drops of blood from the heel or great toe and centrifuges it at the rate of 3,000 revolutions a minute, removing the fibrin from the serum. The fat in the nourishment is determined. The children tested included healthy infants breast fed and artificially fed and atrophic children without fever. Full details are embodied in case histories, curves, and tables. The clouding appears two to three hours after the meal, disappears in seven to nine hours, and is strongest two to four hours after. A feces test proved that the fat was well assimilated. The author concludes that a part of the fat ingested goes into the blood through the ductus thoracicus, and another part by way of the blood capillaries through the cystic veins into the liver. How much is retained there is not known. The fat in butter caused the greatest cloudiness, that in mother’s milk and cow’s milk much less; next in order come sesame oil and cod-liver oil. 330 Scipiades, Elm er: “ Beiträge zur Physiologie des Blutes der Neuge borenen in den ersten 10 Lebenstagen” [Contributions to physiology of the blood of the newborn in first ten days of life].

Scipiades tests the blood of eight newborn healthy infants, using ThomaZeiss’s apparatus for counting the red and white corpuscles and Lacker’s for drawing blood from the great toe. Tables give findings for each of the first 10 days, or tests made upon five infants ¿athed only once after birth and upon three tfiat received daily baths. The only distinction between the two types was that the number of red and white corpuscles was somewhat higher in the children bathed every day than in the others. This may have been due to chance. The number of red corpuscles at birth is unusually large; later few are needed and produced. White corpuscles also decrease. 331 Sedgwick, J. P ., and F. B.

Report of an investigation to determine whether the high uric-acid excretion during the first few days of life is accompanied by a simultaneous increase of this substance in the blood. The Myers-Fine and Lough modification of the original Folin-Denis method for the determination of uric acid was used with minor changes. Daylight was used whenever possible in reading the colorimeter. The uric-acid content of the blood of 31 newborn infants, from content of placental blood to that 10 days after birth is tabulated; also, for comparison, th» uric-acid content in 18 tests of maternal and placental blood. The authors think their finding of parallelism of high uric-acid content and high excretion of this substance during the first three or four days is indirect support of the theory that human fetal tissues possess no micolytic power.

Subcutaneous injec tions of lb cubic centimeters per pound of body weight of a 5 per cent solu tion of glucose produced only a slight rise in blood-sugar concentration ; of 10 and 15 per cent solutions, after one-half hour, a rise to about 0.225 per cent. Intravenous administration of a 10 per cent solution of glucose pro duced a greater rise in blood-sugar concentration, but tue original level was more quickly reached.

For the albumin he took blood from the vein, for the other two purposes from the toe. He tested 152 chil dren, 7 women, and some animals. The viscosity of blood in healthy infants is 3.2 to 3.6 ; in children between 7 and 13 years, 3.75 to 4.1 ; in adults (accord ing to Hess), 45. In mothers it is one-third less than in their newborn infants. The author discusses viscosity theoretically : It is, he says, the content of the plasma in viscous substances, not crystalloids but colloids. From experiments in vitro he concludes that the water content can be traced in the thickening or thinning of the blood and that viscosity shows approximately the carbonicacid content of the blood. The hemoglobin content by Sable’s method was 70 in healthy older children and very much higher in newborn infants.

The author concludes that at birth the opsonic power of the blood serum toward these bacteria is a little less than that of adult serum ; that it falls lower during the first months and reaches adult power at about the second year; that the phagocytic activity of the leucocytes follows a similar course ; that the phagocytic power of the whole blood drops during thè first two months and does not reach that of adult blood until about the third year ; that during the first and second years of life the anti-infectious power of the blood is far below that of the blood in adult life.

In discussing pulse and blood pressure of sick children the author mentions many facts applicable also to the normal infant. He used Gartner’s tonometer in his measurements in the Berlin and Weissensee Infants’ Clinic, greasing with vaseline the ring for the finger, and choosing a time after meals when subjects were quiet. He found a great individual variation in pulse; the blood pressure he believes is independent of pulse. It was on an average 80 millimeters in healthy infants below 6 months and 84 after 6 months. In 200 cases the pressure in right and left hands was the same 138 times, higher in the left 43 times, and higher in the fight 19 tim es; the difference amounted to 5 to 10 millimeters. The pressure in sleep is less than in nursing. The bath increased it in 34 cases out of 50 and decreased it in 7 cases. 370 Churchill, Fleetwood: “ On the rhythm of the heart of the fetus in utero and of the infant after birth.” Dublin Quarterly Journal of Medical Science, vol. 19 (1855), pp. 326-332. Comparing the' rhythm of the sounds of the heart of the fetus and of the Infant shortly after birth the author found a distinct change, the two sounds after birth being of equal strength and loudness and dividing the period of each •pulsation equally. This peculiarity of rhythm persists for about a year and a half and then gradually changes to that of the adult. 371 Clerk, F.

Pulse frequency is greater with a low pressure than with a high. In the school age monocrotism is not observed; there is a tendency to predicrotism rather than to dicrotism— there > a.re t^ a maxima of blood pressure, one in the sixth and the other in the eleventh year. The pulse curve of children is usually unequal ; in many cases arhythmia is noticed. By the age of 15 it is more constant and of dicrotic character, like that of the adult. The size of the sphygmogram is directly pro portional to the blood pressure. 376 Epstein, A l.: Beitrag zur Kenntnis des systolischen Schadelgerausches der Kinder.

From more than 500 readings of arterial blood pressure of normal children of different ages, sexes, statures, and degrees of development (methods described) the author concludes that: (1) There exists a fairly definite average pressure for the healthy infant which increases proportionately with the age of the subject; (2) at puberty there is a marked increase in average pressure' (3) in certain physiological .processes, menstruation, digestion, physical and intel lectual effort, etc., the pressure is appreciably modified. 384 Gunzburg, L. : “ Einfluss des Wachstums auf Herz und Lungen ” [Effect of growth on heart and lungs], Wiener Medisinische Presse, vol 20 (1879) , pp. 908-910. Theoretical description of the development of the heart and lungs from the embryological state to the end of growth. Immediately after birth the heart changes its position and form because Of breathing. The changes in the lungs are still greater and affect their color, weight, consistency, and capacity From birth to puberty the growth of the heart and lungs proceeds rather slowly for a period. From puberty to the age of 20 a more rapid development of the breathing and speaking apparatus takes place. The lungs are then very sensitive and have a low power of resistance. The normal relation of the heart and lungs to each other is often affected by various factors. The pur pose o f the article is to point out two conditions observed by the author at the time of puberty (number o f cases not given) : ( 1 ) Hemorrhages of the lungs: (2) accelerated heart action often combined with stinging pains.

He prefers to use the brachial rather than the radial pulse; pressure is 3 to 15 millimeters higher in the former than in the latter. His long discussion he devotes to three top ics: Pulse and blood pres sure ; blood pressure in normal circumstances; blood pressure in pathological conditions. The average blood pressure of 25 normal children 3 to 15 years old was found to be 116 millimeters; the maximum and minimum were 80 and 150- The average for 8 children from 4 to 6 years was 107, and of 8 from 11 •to 12, 122.

Diastolic pressure was taken in the fourth phase. Table I by the authors gives age, width of cuff, circumference of arm, systolic, diastolic, and pulse pressure by three methods, and pulse rate. Number of cases is not cited. Table II gives pulse pressure from various observers. Table III gives age, systolic, and diastolic pressure. The technique and physi ology . of blood pressure are discussed. Conclusion : The systolic pressure is higher than is generally taught and does not increase from year to year. Diastolic pressure changes very little. Pulse pressure increases most and is the most important determination in children. 395 Jurasz, Anton: Das systolische Hirngeräusch der Kinder [Systolic Cerebral Murmur], Habilitationsschrift, Heidelberg, 1877. 96 pp. Thesis (University of Heidelberg). This work on systolic cerebral murmur of children contains 96 pages and many tables and is divided into a historical section on the work of other investigators and clinical and anatomical sections based on the author’s own investigations. Sixty-eight healthy and sick children between 5 months and 4 years were examined. The murmur occurs only between ages of third to fourth month and fourth to sixth year and is closely connected with development of skull base, especially carotid canal, and probably with foramen spinosum. It is a physiological phenomenon and can not be used in diagnosis of disease. 396 Katzenberger, Arm in: “ Puls und Blutdruck bei gesunden Kindern ” [Pulse and blood pressure in healthy children]. Z tschr. f. K in d erh . [Berlin], vol. 9 (1913), pp. 167-195. The author determined the frequency of pulse in 112 boys and 100 girls from 6 months to 14 years old, using the Riva-Rocci sphygmomanometer and a stethoscope. He found that the pulse and pressure vary widely in children, the pulse being higher and the pressure lower than in adults. The results of his own investigations and those of other students are tabulated, and the effects upon pulse and blood pressure of weight, sex, sleep, position of body, time of day, mental excitement, meals, motion, breathing, and bath are discussed.

China During the physical examination of students in the West China Union Uni versity and associated schools, the writer recorded the blood pressures of 741 students, of whom 443 were under 21 years of age. Pressure was taken with a Nicholson “ l'rinceps ” mercury sphygmomanometer, with cuff Î2 centimeters wide, applied to the right arm while the subject was in a sitting posture. The auscultatory method was used throughout. Systolic pressure was read on the first appearance of sound on lowering the pressure in the cuff ; diastolic pres sure at the fourth point. About one-fourth of the records were taken in April and May, 1924 ; the remainder in September of the same year. All examina tions were made between 2 p. m, and 5 p. m. For comparison the blood pres sures of nine Canadian and United States boys, 14 to 17 years of age, were also taken. These boys, with one exception, were born in Szechwan and, except for furlough periods, had lived there continuously. Mean systolic and diastolic pressures for the entire series were lower than the standards for Anglo-Saxons of corresponding ages. The pulse pressure was as .high as that of the white races. Systolic and diastolic pressures*! thé nine Canadian and United States boys were higher than those of the Chinese; pulse pressure was about the same. The records showed no marked variation of blood pressure with age. Tables and references. Koessler, Mlle.

In the belief that blood pressure should be measured in thereapeutics the authors tested it in the case of 68 healthy children. They took only the systolic pressure and estimated it at least three times on each occasion (the first measurement being ignored on account of child’s nervousness) ; after the first doctor made an estimation the second made a control estimation. A very full description is given of apparatus of von Bosch, of Gärtner, and RivaRocci. In studying one child seventy-five times and another sixty times the blood pressure, the authors found, varied within 10 millimeters of mercury. The results are compared with those of other students. The pressure rose according to increase in years, after the partaking of food (except in case of infants) and of drink, usually after exercising, and always as sequence of nervous excitement. 418 Payan, L., and Ed.

Subjects were divided into several age groups and minimum, average, and maximum pulse rates were recorded for each group The author found that the pulse in the third month has the frequency which it preserves to the twenty-first month ; that from the third month through the twenty-first the pulse of girls is more rapid than that of boys; that the pulse is more rapid when the infants are awake than when they are asleep. Normal variations were as follows : In the second half of the first month, 120 to 164 • from 1 to 2 months, 96 to 132 ; from 2 to 6 months, 100 to 162 ; from 6 months to one year, 100 to 160 ; from one year to 21 months, 96 to 140. 434 Trumpp, J .: “ Blutdruckmessungen an gesunden und kranken Säuglin gen ” [Blood-pressure measurements of healthy and sick infants].

Trumpp measured the blood pressure of healthy and sick infants 1,300 times. Some of the work was done in Munich; but 1,062 measurements on 56 in fants were made at the Children’s Asylum, Berlin. Gartner’s tonometer was used. The newborn showed values no different from older children. The healthy, breast-fed infant showed a blood-pressure curve almost horizontal between 75 and 90 millimeter hydrogen ; 60 was reached only in sleep or in cases of premature birth. Muscular and nervous stimulation and the taking of food increased blood pressure. Three hundred tests on the hands resulted in a higher pressure 122 times for the left hand and 97 times for the right hand, and no difference 81 times. Sixteen tables give temperature weight and blood-pressure curves foy 1 healthy infant and 15 sick ones. 435 V a lle ix : “ Recherches sur la fréquence du pouls chez les enfants nouveaunés et chez les enfants.âgés de sept mois à six a n s ” [Observations of pulse rate in newborn infants and in children aged 7 months to 6 years].

Data were obtained from three series of observations : One of 4 children observed for 24 days, one of 6 children for 24 days, one of 33 children for 25 days. The total number of observations was 567. The author found that the pulse is less rapid in the newborn than in infants of 6% months ; that rise in temperature increases pulse rate ; that the pulse of girls is more rapid than that of boys ; that during sleep the pulse is sensibly retarded ; that from 7 to 27 months the number of pulsations does not change noticeably, remaining at about 126 when the child is in a state of ordinary activity. 436 W ilson , M ay G. : “ The circulatory reactions to graduated exercise in normal children.” Am.

To assist in finding’a criterion of cardiac function applicable to children an investigation was conducted at New York Nursery and Child’s Hospital, and at the' Department of Pediatrics, Cornell University Medical College, N. Y. Twenty normal children aged 6 to 13 years were observed at two-day intervals for two to eight weeks. A total of 500 observations were made. Pulse, sys tolic blood pressure, character, duration and rate of exercise, and clinical re actions of subject were recorded. Typical pulse and blood-pressure charts arè shown. The complete data of one experiment in each of the 20 eases àrè tabulated. The author’s conclusions are that the circulatory response to exer cise in children is similar to that of adults and reasonably constant. The pulse returns to normal within two minutes after exercise to the. clinical limit of tolerance. The type of blood-pressure curve is the best criterion of exercise tolerance and therefore of cardiac function. A delayed rise and summit with a prolonged fall indicate the limit of tolerance, : ‘V https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 176 437 438 PHYSICAL GROWTH AND DEVELOPMENT OP THE CHILD W olfen soh n -K riss, Mrs. P.: “ Über den Blutdruck im Kindesalter” [Blood pressure in childhood].

The author reports his own study of 2,100 apparently normal infants and children. The findings recorded were determined in greater part by palpation Monthly examinations were made during the first year ; annual examinations to and including the twelfth year. Significant changes in size appeared in four groups : 10 days to 1 year, inclusive, 531 cases : 2 years to 4 years, inclusive, 458 cases ; 5 years to 9 years, inclusive, 835 cases ; 10 years to 12 years, in clusive, 276 cases. With reference to the costal margin in the mid-clavicular line, the liver varied from just palpable to 6.5 centimeters below ; it was found 3.5 centimeters, 4.5 centimeters, and 5.5 centimeters below as late as 9 years of age, and fairly often as low as 3.5 centimeters below up to 12 years Neither the state of nutrition nor the type of diet affected the height of the liver. The spleen was palpated below the free border of the ribs in 25 per cent o f the series, the frequency being greatest during the first year. Neither type of feeding during the first year, race, nor nationality of parents had any appreciable effect on the size of the spleen.

Archiv für die Gesummte Physiologie des Menschen und der Thiere [Bonn], vol. 28 (1882), pp. 229-242. After refuting Hermann’s theory on elastic tension of the fetal thorax the author argues that the thorax of the newborn infant, in consequence of respi ratory moyements, is subject to new equilibrium, and discusses mechanics of this change, and. develops his own theory of excess expansion. This rests on the hypothesis that the thorax of the fetus and all parts connected with it grow in a condition, of elastic equilibrium. If a powerful inspiration occurs organs, muscles, etc., are stretched and draw in opposite directions, but not being entirely elastic they retain a certain degree of extension. The author refers to tests without precisely tabulating them. --------- - “ Weiteres über die Entstehung der Aspiration des Thorax nach der Geburt ” [Further on the origin o f. expansion of the thorax after birth].

He again calls Hermann’s theory on elastic tension of fetal thorax a physical impossibility. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GROWTH AND DEVELOPMENT OF PARTS OF BODY 177 Tests on six kids, two lambs, and one infant convinced him that expansion of the thorax arises in consequence of the first powerful movements of breath ing directly after birth. In the human newborn, at least after the first week, there is a negative pressure in the thorax. That it is not so great as -in adults is due to the fact that young tissue has a lesser elasticity coefficient than older and that bronchi and alveoli become thicker and perhaps also more numerous. 444 Billard, G., and P.

Comptes rendus des séances de la Société de biologie [Paris], vol. 94 (1926), pp. 12-13. By this index the authors designate the relation of chest volume to vital capacity. In a series of 150 children they found no correlation between stature or weight and vital capacity, but a fairly constant value, ranging from 4.5 to 5.5, for the above index. 445 Boynton, R uth E .: ‘‘A comparison of normal standards for the vital capacity of the lungs of women.” Archives of Internal Medicine [Chicago], voi. 33 (1924), pp. 292-300.

Eighteen were well ; the others were convalescent from diseases of the lungs or pleura. For each experiment the author gives the age, weight, height, chest circumference temperature, pulse, time of day, duration of study, and quantity of air expired every five minutes. He found that the amount of air expired every five minutes by children from 3 to 11 years old varied between 30 and 47 liters ■ respiration is more active in children than in adults ; in proportion to the sizes o f their bodies the children breathe more air than adults ; in children of the same age the weight, height, and chest circumference bear no relation to the amount of expired air. 447 D oh m : “ Über den Mechanismus der Respiration des Neugeborenen ” [The mechanism of respiration in the newborn]. Archiv für Gynaekologie [Berlin], vol. 35 (1889), pp. 503-504. The author tested with mask and spirometer the respiratory exchange of a very young infant when quietly breathing and when crying; it was 35 cubic centimeters in the first case and 120 to 140 cubic centimeters in the second. There is atelectasis, the author maintains, on the first day of life and often on the second. The air exchange of infants is much greater than that of adults. [Me 44 8 ----------- “ Über die Mechanik der Respiration des Neugeborenen” chanics of respiration of the newborn]. Deutsche Gesellschaft für Gynäkologie, Verhandlungen [Leipzig], 1890, pp. 102-108. The author demonstrated mechanics of infant respiration with dead bodies into which glycerine had been injected. For the normal newborn child there is an exchange with every breath of 35 cubic centimeters of air, which amount may rise to 120 cubic centimeters in crying. The respiratory curve shows no pause between inspiration and expiration. Air exchange with each breath amounts to one-fourth of whole capacity of lungs— considerably more than in adults. Complete development of alveoli of lungs can not be assumed after shallow breathing. 449 Eckerlein: “ Zur Kenntnis des Atmungsmechanismus der Neugeborenen ” [Mechanism of breathing in newborn infants], Zeitschrift für Geburtshülfe und Gynäkologie [Stuttgart], voi. 19 (1890), pp. 120-173. The author discusses the work done on the respiration of infants by Maye, Monti Steffen, Kehrer, Vierordt, Kennebaum, Preyer, Kronecker, Weber, et al. To determine the form of the thorax of newborn infants he made observations for 10 days on 5 healthy children with an apparatus for outlining the longi tudinal profile, and for 6 to 9 days on 28 infants, with a tape measure, to obtain the chest girth. The latter results are shown in tables. The mean for 468 measurements is 32.4 centimeters. Means from 468 measurements of antero posterior and transverse diameters of the chest are 8.7 centimeters and 9.8 centimeters, respectively. The infant’ s thorax is therefore much less flat than that of the adult. To ascertain the changes in the thorax the author made curves of the chest girth of the above 28 newborn infants, which curves show a sinking on second and third days after birth. The lung volume of 4 stillborn infants he found to average 51 cubic centimeters. Further experiments on the living infants showed how the thorax rises and falls in quiet and in deep breathing. The same experiments are conducted by artificial inflation of cadavers. With Marey’s drum the author measured the rhythm of respiration of which he gives many graphs. With a specially made spirometer he tested the respiratory exchange of 5 children during their first 8 or 10 days of life, and made over 100 curves. He found it 2,500 cubic centimeters a minute for crying and 1,700 for normal breathing. The infant has a greater respiratory exchange than the adult. The article concludes with many spirometrie curves o f respiratory rhythm in newborn infants. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 178 PHYSICAL GROWTH AND DEVELOPMENT OP THE CHILD 450 Eckstein, A ., and H .

On the basis of observations upon 230 children from 13 -to 18 years of age the author states that thoracic expansion in breathing is to abdominal ex pansion as 10 is to 5 in the prepubescent period and as 6 is to 4 after puberty ; or, in other words, the pulmonary expansion is horizontal before puberty and horizontal and vertical after puberty. 459 Gregor, Konrad: “ Untersuchungen über die Atembewegungen des K in d es” [Investigations in respiratory movements of the child].

The purpose of this article is to find the relation between the sitting height and vital (or respiratory) capacity in normal children as a means of judging the child’s physical condition. The author gives in two tables the following data obtained by Professor Fabozzi : Age, height, sitting height, weight, chest circumference, and vital capacity for over 1,300 school children 3 to 11 years old. by sex. In two other tables he gives data obtained by himself in a study of 960 children ranging in age from 6 to 11 years old, boys and girls in nearly equal numbers. He gives for them the relation between the sitting height and vital capacity, and in a fifth table he presents an index showing the vital capacity for each centimeter of sitting height. He concludes that the vital capacity, considered by itself, increases with age ; it is greater in males than in females and in the rich than in the poor. The proportion between Vital capacity and sitting height is constant in children. The number which expresses the relation between the cube of the* height and the vital capacity in normal condition fluctuates around 21 ; that expressing the relation between the cube root of the vital capacity and the sitting height is in normal condition equal to 0.16 or 0.17. Both these indexes constitute an objective method for judging whether the maximum quantity o f air inhaled or exhaled by an individual is sufficient for the development of the body.

After a description of his re cording apparatus (Marey’s polygraph from Roth in Prague), of which he gives a picture, the author shows 6 curves of adults’ respiration and 12 of infants’ respiration and notes the differences. Breathing of the newborn agrees with that of adults in that the inspiration passes into expiration without nause and surpasses the latter in duration. On the other hand the infant differs essen tially from adult in absence of respiration pause and in greater frequency and slighter depth of respirations. These differences are to be explained by greater flexibility of children’ s thoraces which follow alteration in the volume of the lungs more easily than in adults, by less energetic contractions of the dia phragm, by shorter duration of circulation of blood, and by very slight thoracic aspiration in the beginning. 469 Rock, F.

The author measured 200 boys and men varying in age from 5 to 64 years to determine the maximum vertical diameter of the lungs of a living being. In several tables be gives separately for each case the age, height, height of spinal column, height of sternum, perimeter and diameter of middle thoracic segment, height of abdomen, hi-iliac diameter, and vertebral diameter. He discusses the tables and concludes that the vertical diameter (he also calls it “ vertebral ” diameter) varies according to age, height of the person, height of spinal column, and all the other factors given by him in the tables. The vertical diameter of the lungs of the adult was on the average 30 centimeters, which is 5 centimeters greater than that generally found in corpses.

The previous literature on vital capacity is extensively reviewed. Full statis tical tables are given. In addition to a verification of his earlier conclusions the author reports that girls may be considered relatively more mature for their age than boys, since their vital capacity forms a greater proportion of the estimated adult maximum. The maximum capacity is reached in the twentieth year : for boys and slightly earlier for girls.

Tabulations were made by sex, quarter years, total years, and sanitary conditions of the home. Children were 6 to 17 years old. From 6 to 13 years, inclusive, the boys had an average of 100 to 200 cubic centimeters’ greater lung capacity than the girls ; from 14 to 17, from about 300 to about 1,100 cubic centimeters. At the age of 11 a slight irregularity was found in the increase curve for both boys and girls.

The aim of this study was to determine to what extent measurements of the vital capacity, as an expression of one aspect of the respiratory function, can be correlated with the exercise-tolerance test as a form of measurement of cardiac functional capacity. To establish a standard for normal vital capacity the authors studied 44 boys and 41 girls from 6 to 16 years of age, expressing the vital capacity on the basis of a square meter of body surface as determined from the height-weight chart of DuBois and DuBois. The average vital ca pacity of the boys studied was 1.902 cubic centimeters for each square meter of body surface : of the girls, 1,837 cubic centimeters. Vital-capacity measure ments were found to show a close relation to heart functional capacity as gauged by exercise tolerance. D. 481 4S2 N E R V O U S SYSTEM A llaria, G.

The author found no case of myopia and only a few cases of emmetropia. Most of the infants showed hypermetria between one-sixteenth and one-twentieth. He concludes that the child’s eye is probably exclusively hyper metropic ; that it is not always blue but often brown ; that the distinction in breadth and appearance of arteries and veins is not so pronounced in children as in adults; and that in many eyes of the newborn can be found remains of pupillary membrane and blood extravasation.

This discussion, illustrated by two figures, of the anatomy of the ciliary muscle is based on arguments concerning preceding theories and on examination of the 36 eyes ^of 18 newborn infants. The ciliary muscle in the newborn is different from that of the adult and is also very varied in different infants. In most of the 18 the separate parts were well developed; in 4 the ring portion was not. In 3 infants the circular fibers were numerous, but in no case did the ciliary muscle consist exclusively of longitudinal fibers. The author speaks of the important röle played by innate individualities of the structure o f the ciliary muscle in myopia and in the general development of the eyeball. Thus he explains myopia where there has never been eye strain and also anisome tropia. Leopold, J. S., and A . Birnhard: “ Studies in the chemistry of the spinal fluid of children.” Am. J. Dis.

In the newborn the lateral half of the ball in its posterior part shows a much greater bulging than in the adult, the cornea has a greater relative thickness, the suprachoroideal space is not yet fully developed, the optic nerve contains as many fibers as that of the adult, and the greater thickness later is due to formation of medulla.

Two long tables for boys and girls separately give age, weight, and height of body, weight of brain, and causes o f death. Other tables give maximum, minimum, and mean weights of these brains. Still others give separately the weights of cerebrum, right and left hemispheres, cerebellum, and rest or the brain. The cerebral hemispheres the author separated from the brain by a section through the pedunculi cerebri. Tie, female brain is always lighter than the male. The brain grows very rapidly during the first year, reaching in the boy 945 to 1,055 grams. It is Usually three times this weight in the fifth -year and thus not much less than the adult weight. The individual variations in brain weight are very great even for the same age, weight, and height.

This article contains two graphs and one table on brain weight at different ages and height in millimeters to 1 gram of brain weight. In 627 cases the author collected the data personally from other investigators. He assembled 2,000 cases. The brain of the newborn girl weighs 330 grams, that of the newborn boy 340 ; in nine months these weights become 90Ö and 1,050, respec tively. Later growth is not nearly so rapid. Till the second or third year the body increases in weight with less rapidity, relatively, than the brain, and from the third to the twentieth year with greater rapidity. During these first 20 years the absolute weight of the brain is always greater in the male than in the female. ----------- “ Über das Gehirngewicht neugeborener K in der” [B r a n weight of newborn children].

Though colors change the relative intensity in different parts remains the same: and everv chromatic peculiarity is strongest in the core, weakening toward the periphery. The author is particularly interested in the system or organ of Rolando. He dissected !)6 brains, which he arranged not according to legal but real age, determined in the youngest by the bony point of the lower epiphysis of the femur (his first two groups cover 15 days each, the others the succeed ing months). He gives a detailed description on the groups, showing how the violet gradually whitens and the cerebral substance becomes denser. The parts covering highest functions develop most slowly. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis GROWTH AND DEVELOPMENT OP PARTS OP BODY 187 510 Pfister, H erm ann: “ Das Hirngewicht im Kindesalter” [The brain weight in childhood]. Arch. f. Kinderh. [Stuttgart], voi. 23 (1897), pp. 164r-192. The author investigated brain weight in 156 children— 88 boys and 68 girls between 1 week and 14 years of age— that had died at the Children’s Hospital o f the Emperor and Empress Frederick in Berlin. Excluding all pronounced cases of hyperemia, anemia, and meningitis he severed the spinal cord at the decussation of the pyramids and weighed the brain with the soft membranes directly after taking it from the cranium. The article contains very full tables of results and a bibliography. The right hemisphere was found to be heavier than the left in 53.2 per cent and the left heavier in 41.6 per cent of the cases regardless of sex or age. The absolute weight of the cerebellum was greater in the male than in the female. 511 ----------- “ Neue Beiträge zur Kenntniss des kindlichen Hirngewichts” [New contributions to the knowledge of the weight of children’s brains]. Arch. f. Kinderh. [Stuttgart], voi. 37 (1903), pp. 239-242. The author presents a table giving the age, length, and total brain weight o f 72 boy infants and 73 girl infants, dissected in Berlin, since 1898. The brain •was separated where the pyramid crosses from the spinal cord, and weighed. The infants came from the lower classes of society. So far as possi ble foreign and pathological brains were discarded. Cases of hyperemia and anemia were noted. 512 ----------- “ Theilwägungen kindlicher Gehirne ” [Weights of parts of chil dren’s brains]. Arch. f. Kinderh. [Stuttgart], voi. 37 (1903), pp. 243-251. The author presents a table of measurements of the brains of 33 boys and 39 girls, mostly in the first year. The dissection was done in 1899 and 1900, the material coming from the Emperor and Empress Frederick Children’s Hospital in Berlin. Pathological conditions were discarded ; the brain was severed from the spinal marrow at the lower end of the pyramid. The tables show age, total brain weight, total weight of cerebrum, and of cerebellum and of the rest of' the brain and of each half of the cerebrum. There was usually a slight difference in the weight of the halves of the cerebrum and great variation in the weight of the cerebellum. The cerebellum also grows much more than the rest of the brain ; i. e., to seven times its birth weight, as compared with four times for the rest of the brain. The male brain was regularly larger than the female. 513 -------— “ Über das Gewicht des Gehirns und einzelner Hirntheile beim Säugling und älteren Kinde ” [W eight of brain and separate parts thereof in infant and older child]. Neurologisches Centralblatt [Leip zig], voi. 22 (1903), pp. 562-572. The author describes the technique of weighing brains of 161 boys and 141 girls _between the ages of 1 week and 14 years that had died in a children’s hospital at Berlin. These brains were from children of the lower classes. So far as possible foreign race and pathological conditions were excluded. Five tables give sex, age, and average weight in grams of the whole and parts of the brains. Fourteen conclusions have to do with the greater weight of the male brain, with more rapid growth of the cerebellum than of the rest of the brain, and difference in weight between halves of brain. 514 Quest, Robert: “ Über den Kalkgehalt des Säuglingsgehirns und seine Bedeutung” [The calcium content of the infant brain and its signifi cance]. Jahrb. f. Kinderh. [Berlin], voi. 61 (1905), pp. 114-121. Incited by Sabbatani’ s theory that a decrease of calcium in the cortex cerebri means increased excitability the author dissected the brains of 12 children, o f whom 2 had had hypertonia and 3 tetanus, and the other 7 were normal (2 of these had died in the fetal stage, 1 had died at birth, and 4 had died later). He treated the brains according to the Hoppe-Seyler method. In the seven normal infants the author found that the calcium content of the brain was very high in the fetus and the newborn but diminished with time, very rapidly in tbe first months and then more gradually. Thus Sabbatani’ s theory is sub stantiated, since all experimentation shows that excitability is least in early infancy. The brains of tbe children that had had tetanus showed a con spicuously low calcium content. 515 Roberts, M . H in e s : “ The spinal fluid in the new-born.” J. A . M. A. [Chicago], voi. 85 (1925), pp. 500-502. In Grady ' Hospital, Atlanta, Ga., lumbar puncture was done on 423 newborn negro infants. The first 100 fluids were examined for cellular content and Wassermann reaction. In the last 327 cases the blood drawn from the longi tudinal sinus was studied for pigment content and Wassermann reaction. The investigation showed that xanthocromia of the spinal fluid in newborn infants is a physiological condition, the intensity of pigmentation being closely related to the physical development of the child. The pigment persists at least until the ninth day, and is cleàred by the fourth week. 12229°— 27------ 13 https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 188 516 517 518 519 PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD Sabin, F loren ce: “ Description of a model showing the tracts of fibers medullateddn a newborn baby’s brain.” American Journal of Anatomy [Baltimore], vol. 11 (1 91 0-11), pp. 113-136.

To determine whether the rapid growth of the cerebellum in infancy is corre lated with the marked development of muscular coordination and activity in this period, the authors devised empirical formulas for the relation between the cerebellum volume and body length in the fetal period, the relation between body length and age in the fetal period, and the relation between cerebellum weight and age in postnatal life. The source material for study is not described in this article. Tables and 1 chart indicate that the rapid growth in the cerebellum in the first postnatal year is to be regarded as a diminishing residuum of intrauterine growth energy, rather than as a result of the stimulation of extrauterine environment.

Weights are given in percentage of dry substance and the total lipoid content is reckoned. Water content of the brain decreases with increasing age. Lipoid content increases. The brain lipoids in the infant consist for the most part of cholesterin, whereas unsaturated phosphatids pre vail in the adult. The infant brain is richer in albumin. It has, then, many peculiarities not only in morphological structure but also in chemical compo sition. Schloss, 0 . M ., and L. C.

An original study of the development of the peripheral nerves in 55 cadavers of children who were from 1 day to 4 years old at the time of death. The author found that the nerve trunks of the children were less developed than those of adults, particularly as regards myelin, which was entirely absent in many nerve fibers and present to a very small degree in others. He quotes several writers who found in infants insufficient development of the central nervous system and concludes that this underdevelopment of the entire nervous system, a peculiarity of infancy and early childhood, is much greater than that of other organs. Several tables are included giving in detail the con dition of the nerves studied. Spitzka, E. A : “ The brain weight of the Japanese.” Science [New York], new ser. vol. 18 (1903), pp. 371-373. After a review of the literature on this subject the author regroups the figures of Taguchi for 597 adult Japanese subjects and 156 children from 2 months to 14 years of age and compares them with figures for Europeans. He finds that the brain of the Japanese grows more slowly during infancy and early youth than does that of the European. T a ft, A .

This study, while largely of adult brains under pathological conditions, has a report of measurements of six specimens, two infants, aged 7 weeks and 4 months, respectively, one child 5 years old, and 3 adult microcephalies.

During the 10 years preceding publi• cation the author weighed the brains of 597 bodies among which were 73 cadavers of males "and females from 2 months to 20 years o'f age. Methods o f weighing are described in detail. Among the 73 he found a range of weight in males from 427 grams to 1,566 grams, in females from 499 grams to 1,366 grams. By tabulating the weights by age he found indications that the male brain develops more rapidly than the female.

A 1 : 1,000 solution of atropin was dropped into the conjunctival sac, and the child was held upright by the nurse. Table gives resulting data on refraction, form of papilla, scleral and choroidal ring, central canal, color, etc. The author con cludes the eye o f the newborn is always of hyperopic formation ; cones are in born ; optical papilla is characterized by gray coloring and scantiness of smaller vessels. No essential difference in refraction of the two eyes was found.

After a historical review of the theories concerning medullary association fibers in the normal cortex the author describes his own methods in dissecting and studying brains, 14 of which were from individuals under 18 years of age, and gives in certain cases a detailed discussion and a curve. He concludes that the newborn has no medullary fibers except in the anterior central winding, which shows bundles of fibers ; the tangential fibers in number and develop ment take a middle position between the inner and outer ones ; nutritional disturbances appear to check the development of the tangential fibers ; this development is not ended in all cortical layers by the seventeeth year ; the number of the tangential fibers is not the same in different parts of the brain ; the Baillarger and the Yicqu ’Azyr striae are due to accumulation of tangential fibers.

Archives de médecine des enfants [Paris], vol. 14 (1911), pp. 250-263. The author studied the physico-chemical characteristics of 43 samples of saliva of 12 infants from 1 to 18 months old in the Medical Clinic o f Turin. Saliva was obtained 8 times by mechanical stimulation, 30 times by taste of saccharin, and 5 times by sodium chloride. He designates his methods of ob taining osmotic tension, electrical conductivity, concentration of chlorides, specific gravity, degree of viscosity and of surface tension. Findings are shown in three tables, and results noted separately on each point. The conclusion is that the principal physico-chemical characteristics of the infant’s saliva are very different from those of milk and of blood. 2 ----------- “ Die chemische Reaktion des Sauglingspeichels” [Chemical re action of infant saliva].

The author concludes that there is no maltase in the saliva of the infant, that for this reason it does not transform the starch in to maltose and that such a transformation does not take place in the stomach, the contents of which, even when alkalinized, reveal no maltase. 4 ----- — “ Recherches sur le pouvoir plastéinogène du suc gastrique des nourrissons sains et atrophiques ” [Researches into the plasteinogen power of the gastric secretion in healthy and atrophic infants].

After discussing the nature, reactions, importance, etc., of plasteinogens the author describes how he experimented on eight infants from 15 days to 18 months old in the clinic at the Royal University of Turin, making 74 test meals of which 39 were of boiled cow’s milk, sometimes diluted, 17 contained sugar, and 18 salt. He observed especially the plasteinogen function and re action, the rennin, and the pepsin. Results are shown in tables. He concludes that the plasteinogen ferment always makes it appearance with the presence of albuminoids in thè gastric juice. The quantity varied directly with the dura tion of the test meal in the stomach. Its function seemed independent of rennin, nor was there any direct relation between plastein and pepsin. De gree o f health did not influence the plasteinogen function. 5 ----------- “ Ricerche ed appunti sulla funzione dello stomacho del lattante ” [Investigations and data on the functioning of the infant stomach]. Rivista di clinica pediatrica [Florence], voi. 6 (1908), pp. 481—502. The author’s own study of the functions of the infant’s stomach, supple mented by numerous quotations from various writers. The author found that the functioning of the infant stomach is imperfectly developed, owing to the following factors : The very slight hydrogen-ion concentration of the gastric contents and the consequent insufficiency of peptic digestion ; insufficient an tiseptic action of the gastric juice and insufficient acid reflex of the pylorus ; absence of osmoregulatory power of the stomach with a consequent lack ot gastric isotonia ; scarcity of some of the principal enzymes. Also the position o f the infant’s stomach was found to be more vertical than in older children and the width of the pyloric ring relatively greater in the first year of lire. All these circumstances make the gastric digestion or protein substances quite imperfect in comparison with that of the adult. 6 ----------- “ Richerche sulla lattasi nella saliva del lattante” [Researches on lactase in the saliva of the infant]. Riforma medica [Naples], vol. 26 (1910), pp. 561-562. To determine whether the saliva of infants contains lactase the author studied the saliva of 17 infants 3 to 17 months old, in a clinic of the University of Turin. Some were fed. at the breast, others at the bottle ; 12 were sick at the time of the study. In most cases the saliva was extracted directly from the children’s mouths. In no case was lactase found. 190 https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis METABOLISM 7 191 A lla ria , G.

[Berlin] new ser. vol. 74 (1911), pp. 252-273. The author studied initial digestion through saliva in eight infants from 1 to 10 months old in the clinic of the Royal University of Turin. With his ap paratus for the purpose he extracted saliva from the mouth and also milk saliva after the children had begun to suck at the bottle. After being swallowed was , at ®5Ce raised from the stomach. These three fluids and the sterilized cow s milk used as food were all tested for cryoscopic degree bv Beckmann’s thermometer, specific electrical conductivity at 18° C., concen tration of chlorides reckoned as sodium chloride by Wohlard-Koranyi’s process, extent of inner rubbing with vertical viscosimeter at 18° C., degree of surface tension by stalagmometric process at 18° C., and in many cases the active reaction or concentration of hydrogen ions. For the test meals the author used isosmotic solutions of full milk with 10 per cent lactose solution hyposmotic solutions of diluted milk with 3 per cent lactose solution, and hyperosmotic solutions of sweetened milk with 15 per cent lactose solution Results are shown in three tables, each containing data on 24 experiments, and are also discussed. Infant’s saliva possesses an important physico-chemical property in diminishing the molecular concentration of fluids and thus the degree o f osmotic tension. It also moderates the reaction and makes liquids less irritating to the stomach. 8 ~ — “ Untersuchungen über Lösungen im Säuglingsmagen ” [Investigations on Solutions in the infant stomach]. Jahrb. f. Kinderh. [Berlin] vol. 66 (1907), pp. 259-285. The author conducted experiments on the solutions in the stomach of five healthy and two atrophic infants in the pediatric clinic of the Royal University of Turin. The quantity in his test meals he regulated according to age The meals were of four kinds : Pure cow’s milk, modified milk, sugar solutions, and salt solutions. The cryoscopic grade was determined with the Beckmann ther mometer, the electric conductivity with a Wheatstone bridge, inner friction with a viscosimeter, the surface tension with the stalagmometric method of Traube, the specific gravity of 18° C. with a pycnometer, the total acidity of the mtrate fluid with sodium hydroxid N /50 and with litmus paper, chloride by the Wohlard-Koranyi method, and sugar by the use o f Fehling’s solution. A final conclusion is that the solutions in the infant stomach tend slowly to approximolecular exchange the degree of osmotic concentration of the blood, and that the frequent sign of hyposmosis is due to the disturbing element saliva, which being strongly hyposmotic, disturbs the physical processes striving after an equilibrium. One can not ascribe an osmoregulating function to the infant stomach; there is no gastroisotonia in infants. 9 —----- “ Untersuchungen liber Wasserstoff-Ionen-Konzentration im Sauglingsmagen ” [Investigations on hydrogen-ion concentration in the infant stomach]. Jahrb. f. Kinderh. [Berlin], vol. 67 (1908) no 123-142. The author studied acidity in the case of nine infants, between 6 and 18 months old, healthy so far as the alimentary canal was concerned. FortyiT e L , ies were made. The greatest acidity found corresponded to about 1/1.500 of a normal solution of hydrochloric acid. It was 50 to 100 times less_ than that of adult. Free hydrochloric acid was lacking in all 48 tests Unlike those of adults, infants’ stomachs showed a great difference in degree between active and potential acidity. Since the active acidity is far below the percentage for the optimum of pepsin digestion, the latter finds unfavorable conditions in the infant stomach. The low active acidity limits its function to preparing the digestion of albumins, which takes place almost entirely in the intestine. The infant stomach has only a very weak antiseptic power. The tables of data arranged according to diet cover six pages. 10 A llio t, Leon: La capacité stomacale du nouveau-né.

The article contains 27 figures of the stomachs of infants and young children on different diets. The great difference between infant and child was found to be that the infant’s stomach has a horizontal position and the child’s stomach a vertical position. Unlike Flesch and Peteri, the authors found peristalsis in the infant stomach. The latter also has a large air bubble. When the diet is changed from milk to gruel, mush, etc., the form and position o f the stomach also change. Position of standing and walking also affects it. Pathological conditions are briefly discussed. The article concludes with short case histories of 13 infants, whose stomachs appear in one or more o f the figures, and with a bibliography. https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 192 PHYSICAL GROWTH AND DEVELOPMENT OF THE CHILD 12 Aron, H a n s: “ D as Salzsäurebindungsvermögen von Frauen- und Kuh milch ” [The capacity of human and cow’s milk to combine with hydrochloric acid]. Jahrb. f. Kinderh. [Berlin], vol. 79 (1914), pp. 288-304. The stomach of the infant is much poorer in acid than that of adults, especially in so-called free hydrochloric acid. The latter Hess found in the newborn before the first meal, not afterwards. This denotes an [H+] = I X 10~4. In fact, it is a question whether there is any peptic digestion in the infant. Muller ascertained that a positive Congo paper reaction is obtained in water with 0.001 per cent hydrochloric acid, in human milk with 0.1 to 0.16 per cent, and in cow’s milk with 0.3 to 0.35 per cent. Therefore the milk may be the cause for the low acidity in infantile digestion. The author gives four tables of results from his experiments concerning the acidity in mixtures of hydrochloric acid with human milk, with cow’s milk, with water, with cow’s and whey. A graph also shows the contrasts. His methods and apparatus are described for the [H+] and calorimetric tests with indicators. To obtain a certain degree of acidity cow’s milk requires three to four times as much hydrochloric acid as human milk. 13 A sch off: “ Zur Histologie der Darmschleimhaut des Neugeborenen” [Histology of intestinal mucous membrane of newborn].

Aschoff refers to his examinations of the histology of the intestinal mucous membrane of the newborn, without describing his material. His discussion constantly cites other investigators. He ascertains histological differences between newborn and adults. As seen through the microscope the goblet cells are much more numerous, and production of mucous is much greater, than with adults. 14 A urnham m er, A lb e r t : “ Über die Unterschiede der Magenverdauung bei natürlicher und unnatürlicher Ernährung ” [Differences in the gastric digestion of natural and artificial diet].

One table gives for each subject extensive data, in cluding coagulation and pepsin digestion. These last are treated in a second table, giving time of action for both human and cow’s milk.

After discussing former investigations on the child’s intestinal canal the author describes his own dissection and study of a 4-month fetus, a 7-month fetus, a newborn infant, a child of 1 year, and a child of 3 years. He "himself drew the 15 figures that he presents in 2 plates. He discusses in turn the stomach, cardia, fundus ventricoli, pylorus, duodenum, jejunum, ileum, and colon. He believes that without regard to the muscles the intestinal wall is characterized by two things: The surface of the intestine is constantly increas ing through augmentation of the villi, and the number of glands is consid erably increased from the fetal period to later periods. 17 Bauer, Ludw ig, and Ernst Deutsch.: “ Das Verhalten der Magensäure, Motilität, und Resorption bei Säuglingen und Kindern unter physiolo gischen und pathologischen Verhältnissen ” [The behavior of gastric acidity, motility, and absorption in infants and children under physi ological and pathological circumstances]. Jahrb. f. Kindrh. [Berlin], vol. 48 (1898), pp. 22-71. The authors describe their investigations concerning the gastric acidity, motility, and absorption of eight healthy infants a few months old and nine healthy children from 2% to 12 years old, also of many sick children. One or two hours after a breakfast following a night of fasting the stomach con tents were removed and examined. Resorption was tested by the Penzoldt and Faber method; i. e., potassium iodide was given in gelatine pills, and the urine and saliva were analysed. For motility, doses of 1.5 gram of salol were ad ministered and the urine controlled after 10 minutes (Ewald) or 10 hours (Huber) with liquor ferri sesquichlorati. The tables of results fill 17 pages. The author finds in healthy infants a few months old lactic acid in the fore- https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis METABOLISM 193 ground and in infants over 6 months old about the same percentage of free hydrochloric acid as in adults. They find potassium iodide in the saliva after 4 to 7 minutes, and in the urine after 7 to 15 minutes. In healthy children they find first lactic acid and then hydrochloric acid prominent as digestion progresses. In motility and absorption these children differ hut slightly from adults. 18 Beneke: “ Über die Länge des Darmkanals bei Kindern, sowie über die Oapacität. des Magens Neugeborener ” [Length of intestine in children and also capacity of stomach in newborn infants].

In the vascular system the arterial vessels are relatively wide at birth and narrow at puberty, after which they grow large again. The carotids, however, do not change, wherefore the blood pressure in the brain remains the same. The author has measured also the heart, lungs, etc., of children but here devotes most space to his work on the intestines and the stomach. The length of the small intestine stands to the height in the relation o f 570 to 100 in newborn infants, 660 to 100 in second year, 550-600 T° 100 in the third year, and 450 to 100 after growth stops; that is, the intestine is longer m children than in adults, in which fact, the author thinks, lies the secret of growth. He found a greater area for intestines of children than of adults, by examining the organs in water. He determined also a greater cubic capacity for intestines and greater metabolism in children than in adults. The capacity of the stomach he discovered to be 35 to 43 cubic centimeters in newborn infants, 153 to 160 cubic centimeters after the four teenth day, and 740 cubic centimeters at the age of 2 years. On dividing his subjects into normal, atrophic, and hypertrophic he ascertained that for 100 centimeters of body length the length of the small intestine was 313 centi meters in the atrophic, 407 centimeters in the normal, and 447 centimeters in the hypertrophic. 19 Biedert, P h .: “ Über normale Milch Verdauung ” [Normal milk digestion]. Jahrb. f. Kinderh. [Leipzig], new ser. vol. 28 (1888), pp. 344-384. The author’s theories are constantly compared with those of Escherich. Four chemical analyses are described: Cow’ s milk feces, cow’s milk casein, coagulated casein, and milk curds in consumptive stool; also four cases of nutrition from the long series observed carefully during 10 years in the hospital at Hagenau, showing the partial success of the Soxhlet process; also five cases of nutrition with meal. 20 Blagodatny, H élène: “ La traversée digestive chez le nourrisson’’ [The passage of food through the digestive tract of the infant]. Nourrisson [Paris], vol. 11 (1923), pp. 331-341. The author studied by means of the X rays the passage of food through the digestive tract of normal infants ranging in age from 6 days to 11 months. The number o f subjects is not given. For these experiments the infants were fed at first on milk alone and then on milk mixed with a 5 per cent solution of carbonate of bismuth. The author describes the gastric stage of digestion, discussing in detail the vertical and transverse forms of the infant stomach, then the jejuno-ileal, and finally the intestinal stage, stating for each group the average time during which the food remained in the investigated part of the digestive tract. 21 Bleyer, A .

The author dissected and studied the alimentary canal of 5 normal infants and of 10 that had died of gastroenteritis, first injecting 100 to 150 cubic centimeters of a 1/10 formalin solution. He describes both stomach and intestine in detail and presents a table showing Paneth’ s cells in various parts of the intestine. The distinction between the stomach of the infant and that o f the adult does not rest upon the development of the single^gland cells which are as much developed in the child as in the adult, but upon the number of the glands and the gland cells, and also upon the arrangement of the glands. The mucous membrane is little developed in the stomach but much so in the intestine, which is longer than that of the adult. Bibliography. 23 Borie, P. René: L ’estomac du nourrisson.

This article discusses Röntgen investigation of the alimentary canal after the first year, as conducted by other students, and author’s own observations on the time required by the stomach and small intestine for emptying. Twentythree children between 1% and 14 years, healthy so far as digestion was concerned, were studied during the period 1919 to 1921 after a meal of barium sulphate and apple sauce. Contrasts with corresponding phenomena in adults are constantly drawn. Two tables give full data on the 23 children. Food began to enter the small intestine after one to two hours and to leave in two to four hours; it began to leave stomach after one to three hours, usually after two hours.

The authors studied the gastric tonus and hunger contractions of many vig orous newborn infants while the infants were asleep, and found the contrac tions in evidence shortly after birth before any food had entered the stomach. The phenomenon is like that in the adult except that the periods of motor quiescence are only 10 to 15 minutes. Two tracings show the contractions in a 9-hour-old infant and in a 9-day-old infant. 27 Clarke, T. W . : “ Gastric digestion in infants.

In 1907 the author was appointed to the staff of the Rockefeller Institute for Medical Research and undertook a long series of investigations on infant digestion. His report, published in 1909, was followed by a number of articles by American and foreign observers, which this article summarizes and com pares with the author’s own work in an effort to learn the truth as to the value of gastric analysis in infancy. The conclusion reached is that much more investigation and practical application of the results on ill children will be necessary before any facts are established. The article contains a descrip tion of the author’s apparatus for removal of stomach contents.

In order to determine the effect of certain foods on gastric digestion 122 observations were made on 22 infants (age not given) at the New York Nursery and Child’s Hospital. The children were given test feedings of lactose, lime water, and barley water in various combinations with cow’s milk and human milk. Sodium citrate was also added to the cow’s milk formula. Gas tric analyses were made from these various kinds of feedings, and the results tabulated, summarized, and applied. 30 Cowie, D. M., and W m .

A report of experimental studies on a large number of infants, by examina tion of stomach contents. Technique is not fully described. Tables show 107 tests on about 40 infants, aged 1 day to 23 months, giving food (breast or formula) time in stomach, amount taken, amount recovered, condition of https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis M ETABO LISM 195 lavage, percentage and character of curds, presence and condition of mucus, and acid content. The progress of the secretion of mucus in the case of two infants is shown by charts. The effects of basic calcium casein and of sodium-citrate feeding are illustrated by tabulated »results of a small number of experiments. The author concludes that the infant’s stomach secretes all the digestive juices from the first day of life ; that free hydrochloric acid rarely occurs in the infant’ s stomach during the active part of the day ; that a total acidity value from 8 to 30 offers the normal stimulus for pyloric relaxation ; that basic calcium casein delays the evacuation of the stomach contents ; that sodium citrate inhibits the action of rennet ; that the curds normally present in the infant’s stomach are paracasein hydrochloride. 32 33 CrisafL, D. : “ La funzionalita del fegato nei bambini provate col levulosio ” [Liver function in the child as indicated by the use of levulose].

A brief account of the author’s study of several children (number and ages not given) for the purpose of studying the functioning of the liver by means of levulose. In the well children the author found no relation between the quantity of levulose utilized and the weight of the body. Most illnesses did not seem to affect the functioning of the liver.

Making no mention of personal experiments the author discusses the physiological function of the stomach of the breast-fed and the artificiallyfed infant. Whereas, he states, the breast-fed infant has digested his meal in 1% to 2 hours and may safely receive another after 3 hours, the artificiallyfed ‘ infant requires 3 hours to digest a meal and should not begin a second until 4 hours have elapsed. According to the author, the antiseptic function of free hydrochloric acid is impaired if food is ingested before a former meal is thoroughly digested. 35 Dargein, Pierre: “ Surface et volume comparés de l’estomac et du duodénum ” [ Surface and volume of stomach and duodenum com pared]. B ib lio g r a p h ie a n a to m iq u e [Paris and Nancy], vol. 7-8 (18991900), pp. 207-216. After presenting a discussion and tables on the dimensions of the stomach and duodenum and the relations between them in the case of 22 adults, the author gives a table of the length of the greater curvature, of the capacity, and of the surface of the stomach of 8 infants of ages from birth to 11 months. The surface of the mucous membrane of the stomach varied with age. At birth it was 12 square centimeters, at 6 months 67, at 1 year probably 140. 36 Davidsohn, Heinrich: “ Beitrag zum Chemismus des Säuglingsmagens” [The chemistry of the infant stomach]. Z ts c h r . f. K i n d e r h . [Berlin], vol. 2 (1911), pp. 420-428. The author believes that not titration but the concentration of hydrogen ions is the only measure for the acidity of a fluid. He made five gastric studies on two healthy infants, two on one retarded child and one on a very young infant, all artificially fed and without digestive disturbances. In every study he ascer tained the presence of pepsin in the stomach, which, however, took no part in digestion. Different kinds of feeding produced almost no variation. He accepts the identity of pepsin and rennet. 37 ---------- “ Beitrag zum Studium der Magenlipase” [Contribution to the study of gastric lipase]. B e r li n e r K l i n i s c h e W o c h e n s c h r i f t [Berlin], vol. 49, pt. 2 (1912), pp. 2080-2081. From his experimentation on adults and children (number not specified) the author believes that the lipase of pancreatin solution has optimum effectiveness with a slightly alkaline reaction corresponding to normality in hydrogen ions of 1 X 10~8. The optimum of lipase action in gastric secretion is found with a slightly acid reaction. After a fatty diet the stomach content shows a weaker acid reaction than usual, and this is especially important for the infant. The author is convinced of the existence of a gastric lipase which can be measured quantitatively and evaluated clinically. To obtain the pancreatic secretion of infants he used the duodenal tube of Gross as modified by Hess. 38 ---------- “ Beitrag zur Magenverdauung des Säuglings ” [The gastric di gestion of the infant]. Z t s c h r . f . K i n d e r h . [Berlin], vol. 9 (1913), pp. 470-493. After appraising his own work and that o f other students on infant’s gastric digestion, the author concludes that reaction of milk digestion at its height is always acid, corresponding to [H] of 1X10-®, by which coagulation, lipolysis, https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis 196 P H Y S IC A L G RO W TH AND D EVELO PM EN T OP T H E CH ILD and casein digestion (through rennin) are optim al; digestion is governed first by coagulation and secondly by lipolysis; duration of digestion, best seen through Röntgen photographs, is about 1% to 2% hours in the breast-fed and 3 to 3% hours in the artificially-fed infant. The author describes methods and results of investigation on the amount of acidity and testing of ferments. One table gives results of eight tests of [H+] on undiluted and diluted gastric solu tion. There are five tables and two graphs. The author ascertains the occa sional presence of pancreatic secretion and raises the question whether or not lab and pepsin are the same. 39 Davidsohn, Heinrich: “ Beitrag zur Physiologie und Pathologie der MagenVerdauung beim Säugling ” [Physiology and pathology of gastric digestion in the infant]. A r c h . f. K i n d e r h . [Stuttgart], vol. 69-70 (1921-22), pp. 239-255. From 53 double experiments on 30 infants the author concludes in opposition to Schackwitz that removal of stomach contents in two unequal portions gives varying acidity determinations. He conducts other experiments testing age and diet as affecting digestion, in both artificially-fed and breast-fed infants. In artificially-fed infants the pH of the stomach contents does not appreciably increase during the nursing period. In breast-fed children the pH is low during the first six months; thereafter it increases rapidly till it permits peptic diges tion. Twenty of these tests were carried out with seven infants. Factors affect ing the pH are the hydrochloric-acid content, the power in the milk to bind it, the reaction of the milk and motility of the stomach, the age and constituion of the child, etc. The article contains 17 tables. 40 ---------- “ Die Pepsinverdauung im Säuglingsmagen unter Berücksichti gung der Acidität” [Pepsin digestion in the infant stomach with ref erence to acidity]. Z t s c h r . f . K i n d e r h . [Berlin], vol. 4 (1912), pp. 208-230. The author considers many sets of experiments conducted by other students, describes a series of experiments by Michaelis and himself on the dependence of pepsin digestion upon acidity, whereby they determined that the optimum of pepsin activity attends an [H+] of 1,610 X -2 and mentions tests by Salge and himself on about 10 breast-fed and artificially-fed infants wherein the stomach content removed one to two hours after a normal meal gave a [H+] of about 5.6 X 10-5. The difference between free and bound hydrochloric acid is only quantitative. A tolerably high acidity is necessary for pepsin digestion. The acid in infants; stomachs is lactic acid, but it is too limited in amount for activating pepsin digestion, and the author concludes that the latter is sacri ficed for the sake of the fat splitting of the lipase in the stomach for which the optimum is not an acid but a natural reaction. He agrees with Pawlow, who through tests with various kinds of foods has shown that the difference in the gastric secretions of adults and infants is only apparent. 41 -------- “ Molke und Magendarmfermente ” [Whey and ferments in the alimentary canal]. Z t s c h r . f . K i n d e r h . Originalien [Berlin], vol. 8 (1913), pp. 178-186. The important fermentative processes in the infant stomach are coagulation and fat splitting. The author’s investigations on whey and alimentary ferments were conducted by the gas chain method. The reaction o f human milk is ap proximately neutral, more acid than blood, and not very different from that of cow’s milk. The reaction of human milk was (H+)— 1.1 X 10-6 and of cow’s milk [H + ]= 3 X 1 0 -7. Human milk showed no coagulation in 20 hours, whereas cow’s milk showed coagulation in 36 to 107 minutes. The reason is the differ ence in salt content. The more diluted the cow’s milk the longer it requires for coagulation. In an appendix the author gives tables on gastric lipase, pan creatic lipase, and lactase. 42 -------- “ Neuere Arbeiten zur Physiologie und Pathologie der Magenverdauung beim Saugling” [New work on the physiology and pathology of gastric digestion in the infant].

A critical review of current theories on the gastric digestion of the infant The presence_of pepsin in the stomach juices and in the mucous membrane of the_stomach is proved; but is this pepsin effective? Three methods o f investi gation have been tried : Testing stomach content for products of protein decom position, artificial digestion tests with stomach content, and determination of stomach acidity, All the work of note along these lines is discussed by the author. He concludes that peptic digestion has not been proved by the first two methods. Acidity of the infant stomach with both breast and bottle feeding amounts to [H ] = 1 X 1 0 - B. But peptic digestion of infant begins with [H ]= = l X 1°-4 and is optimal at 2 X 1 0 -2. In the breast-fed infant till the ninth month and in the artificially-fed infant throughout suckling period, practically no peptic digestion of milk takes place. 43 -------- “ Untersuchungen fiber das fettspaltende Ferment des Magensaftes nebst Angaben zur quantitativen Bestimmung derselben ” [Quan titative investigations on the fat-splitting ferment of the gastric secre tion].
