With reference to height, it is seen from Table 10 that the 

 boys in grade 7A are invariably taller than those in the next 

 higher grade. This is true in each one of the age-periods. 

 This condition is directly opposed to the findings of the other 

 investigators. On the other hand, boys show increasing heights 

 from grade 7B through 8B for the two age-periods 14J to 15, 

 and 15 to 15J. The graduates are taller than the 7 A boys in 

 every half-year except the second. Similarly, with the excep- 

 tion of the first half-year, the high school boys are taller than 

 the 7A boys. When we consider the two-year period as a 

 whole, the high school boys are markedly taller than the boys 

 in 7A. 



The girls present a lesser departure than the boys, from 

 what we should expect on the basis of other investigations. 

 In the first and second half-years there is a definite increase in 

 height from grade 7 A to 8B. In the third half-year this con- 

 dition is limited to grades 7B, 8A and 8B. Graduates are 

 taller than the 7A's in the first, second and fourth half-years. 

 The high school girls are taller than the 7A's in every half- 

 year. For the two years combined, girls show a steady in- 

 crease in height from grade 7 A to grade 8B. The graduates 

 and high school girls are shorter than the 8B girls, but mark- 

 edly taller than those in grade 7A. 



The relations of weight to school grade are slightly differ- 

 ent. For the boys the weights increase in the second and third 

 half-years for grades 7B, 8 A and 8B. In the first half-year the 

 weights of boys increase from grade 7A to 8A, while the weights 

 of 8B, graduate, and high school children fall below those for 

 grade 7A. In the second half-year, the 7A boys are heavier 

 than those in all the other grades, except 8B. The graduates 

 and high school boys are lighter than the boys in 7 A in the 

 first and second half-years. In the third half-year the 7A boys 

 are slightly heavier than the graduates, but lighter than the 

 high school boys. In the fourth half-year both the graduates 

 and the high school boys outweigh those in 7A. 



The girls in the first half-year show an increase in weight 

 for grades 7A, 7B and 8A. Graduates are heavier than 7A 

 children, and the high school girls even more so. In the sec- 

 ond half-year the weights fluctuate from grade to grade, the 

 7A children being heavier than the others, except for grade 8A 

 and high school girls. In the third half-year the weight in- 

 creases for grades 7B, 8A and 8B. Here the 7 A children are
