AVERAGE ANNUAL GAINS IN WEIGHT 



Men and women attain adult size during the first eighteen years of their life. The 

 gain is exceptionally rapid during the first year and again during adolescence. 

 Twelve-year-old and thirteen-year-old girls are larger than boys of the same age, 

 for they grow faster during the twelfth year. The boys, however, overtake them dur- 

 ing the fifteenth year and get progressively farther ahead during the fifteenth to the 

 eighteenth year. (The weights represent gains in weight)
