    Legends for the tables are shown translated here :
    Table I. (p. 29) Standard height and weight for American born Japanese, with Rohrer's index, from 6 to 17 years of age. This table has been prepared when the fourth annual measurements were finished in 1934, totalling 2, 232 children, from the arbitrarily smoothed up cuives. Now, since the last measurements are added, making a total of 2, 583 in 1935, the nevv smoothed-up curves are of course possible. But they do not show more than a very slight change. The standard curves of 1934, therefore, have been used in analyzing and comparing figures of five consecutive measurement lists.
    Table 2. (p. 30 for boys) and 3. (p. 30 for girls) Measurements of American born Japanese children, from 1931 to 1935 inclusive, giving height, sitting height, iliac spine height, leg length, with values relative to stature, body types, weight and Rohrer's index.
    Table 4. Measurements of American born Japanese childlen, from 1931 to 1935 inclusive, giving bicristal width, bisacromial width and their relative values to est-ature.
    Table 5. A child with sitting height greater than the iliac spine height, is designated as of thoracic or T type. A child with sitting height less than the leg length, the leg or L type. If the sitting height is greater than the leg length but smaller than the iliac spine height, it is called the intermediate or M type.
    The change in body types, as taken from the Table 2, and 3 should be as follows :
    Boys, age 6-10, T TTML Girls, age 6-10, TTTML
    But in reAlity, in examining individually the tables for five consecutive measurements, we find that the pe-rsistent L type for five times exists in 16 cases in boys, while in girls, 19 cases. There can be no conclusion drawn from it, except that the boys and girls alike, from 6 to 14 years of age, gradually proceed from T to M type and then to L tyr, after which boys seem to persist maintaining the L type, while gir's will again go back to the M type. In other words, the growth of legs overtakes that of thorax in the same way in boys and girls during the sexless age, that is, before the girls have the first menstruation. In boys, thereafter, the thorax never overtakes the leg, while the growth rate of girls' thorax increases again, overtaking the leg length slightly, making the ultimate type of girls to be M, and of boys to be L.
    Table 7. Developmental Classes.
    In studying the bodily development of the childrep from the individual data, the following four classes may be recognized; in height development as well as weight development.
    Class A (puild and development goo d)
    To this class belong all boys and girls whose 1931 value, 195 -value and, 4 years growth in height and weight are above the norm.
    Class B (Development good.)
    To this class belong those whose 4 years growth is above the norm although 1931 value or both 1931 and 1936 values do not quite reach the north.
    Class C (Build and development subnormal)
    To this class belong all whose 1931, and 1935 values as well as 4 years' growth are below normal. It may mean simple maldevlopment or hereditary small build, or from some unknown cause the growth retardatign period came a little earlier than average. These do not necessarily mean ill-health.
    Class D (Development retarded)
    To this class belong all whose 1931 value is above the norm, but the 4 years' growth is below tfe norm, the 1935 value being above or below the norm. Even those whose 1935 value is still above the norm, will sooner or later airop to below the norm, due to deficiency in development:
    These classes apply to both height and weight. Those who have Class A height usually have Class A weight, but not always. The same is true with other classes.
    Table 8, Ages of the first menstruat'on of American born Jar anes girls are found to be as follows :

    Physical measurements of the Chinese inhabitants of Tatung in Shansi province, of the southern part of Chahar province, of Hopei province, as well as of, e Mongolians in Uran-chapp province in Inner Mongolia.
    The biometric findings of the Chinese living in Tatung were compared with the data obtained by. other authors.
    It has been found from this comparative study that the physical characteristics of the inhabitants in Tatung have many points in common with thoe of the Manchurians (Tungus) of Aigun in North Manchuria

    I investigated the blood groups of the Chinese living in the northern part of Shansi province of China. Among 206 individuals tested, 54 belonged to 0, 54 to A, 75 to B and 23 to AB.
    I compared the distribution of blood groups, by the z2 test method, among the people of this district with that of the Chinese in other provinces of China, as well as with that of the Mongolians, Tungus, Koreans and Japanese.
    I could find no difference in the distribution of blood groups between the Chinese in this district and that of the Chinese in Manchuria, Shansi, Shensi, Honan, Anhwei and Szechwan provinces of China.
    The sirne holds true between the Chinese in this district and the Mongolians, Man-. churians and Koreans living in the northern and middle parts of Korea.

    For each prefecture in North-eastern and Kanto District the gravity center of population in 1920, 1925, 1930, 1935, 1940, 1946, andthe geographical center were computed, the result beiAg shown in Table 1 and figures in the text.
    The direction and distance of the population centerfrom the geographical center and those from the position of prefectural government were discussed. Moreover, the, change of the population .centers before the war and after it was studied.

    吉田章信氏の資料を用い,次の樣な二樣の仮定に基いて,人間の思春期以後の身長に関する二つの成長方程式を求めた.
    1.成長速度は時間に比例して増大するが身長の発育値が一定値に近づくにつれて減少する.
    2.成長速度は身長発育量に比例して増加するがその発育量が一定値に近づくにつれて弱まる.
    この二つの微分方程式を解いて得られる諸常数を最小二乘法で決定し,何れも実測値とよく一致するのが見られた.これらの方程式は基準値設定の際に必要になる実測値の平滑化操作の場合に利用することが出來る.

    Data of stature and chest circumference of boys and girls in the age period 6.18 were treated statistically and the following findings were obtained. Relative chest circumference stand, generally speaking, in inverse correlation to stature, coefficient of correlation being negative, except in intermediate ages, where, especially in the age 14 for boys and 12 for girls, correlation nearly disappears, and the variance of averages each of different stature classes becomes minimum at this time. The variance of relative chest circumference calculated for each stature class is larger in this intermediate period, so that the variance (or the standaid deviation a) of relative chest circumference calculated for each age period irrespective of the stature shows the values as entered in the table (Table 1 on p. 58), where the left half corresponds to boys and the right half to girls.
    It is a remarkable fact, as is already pointed out in the author's previous paper, that the dependence (inverse correlationship) of relative chest circumference on stature is suspended during the intermediate period, where the most accelerated growth in the puberty occurs.
    Legends of accompanying figures:
    Fig. 1. Means of relative chest circumference of boys (full line) and girls (dotted line) for each age period. Age period 6 or 6.7 (in table 1) contain subjects of not less than 6 years and less then 7 years of age.
    Fig. 2. Relative chest circumference on the ordinates and stature class on the abscissae. For boys of 6.7 of age. The parallelogram in dotted line shows diagrammatically the general aspect of dispersion. Each of the vertical full lines visualize the range: average ±σ for each stature class. Averages are connected by the zigzag line MM'.
    Fig. 3. The same as Fig. 2, for boys of 14.15 of age.
    Fig. 4. The sane as Fig. 2 and Fig. 3, for boys of 17-18 of age.
