 the formula for boys, the figures being respectively 2317 and 23*23.

Accordingly it may fairly be concluded that the formula established for 

 boys holds for young adults, and therefore accurately represents the relation- 

 ship existing between the body-weight and the body-length in males 

 throughout the period of growth from birth to early adidt age.
