where g is the weight, I is the length, d is the depth, and k is a 

 constant. Independently of this Crozier and Hecht ('14, p. 145) 

 found a more general relation between body measurements and 

 weight. Since depth and width are each linear functions of the 

 length, the values of depth and width divided by their respective

'tangents' (c) can be substituted for two of the length factors in 

 the weight-length equation (p. 382). This equation then be- 

 comes 



weight = K X length X width X depth. 



The values of the constant K are determined directly by a com- 

 parison of figures 1 to 5 with figures 6 to 10 or indirectly from
