DISTRIBUTION OF WEIGHT ACCORDING TO AGE OF ACCEPTED 

 UNITED STATES RECRUITS (WHITE) 

 1906-1915, PER 1000 



The corresponding distribution of weight according to age of 

 accepted colored recruits is presented in the table below :

Mr. Arne Fisher has also worked out for me the frequency curves 

 for weight according to age for white recruits. In the analysis of these 

 curves he points out that on account of the military requirements as to 

 the minimum permissible weight of recruits there exists a well-defined 

 lower limit for the range of the curve of a more pronounced character 

 than in the case of the measurements of stature. On this account the 

 curves are rather skew in appearance and therefore represented by the 

 type known as the Poisson-Charlier B Curves. The theoretical frequency 

 distribution by five-pound groups per 1,000 recruits at single years 

 of life under age 25 and at ages 25 and over, considered as a group, is 

 as follows :
