A Study of Grozuth 



19 



Comparison of females and males of approximately the same 

 initial weight, ought to show whether the percentage increment is 

 greater in the females or in the males. The data on this point 

 are not conclusive, as shown by a review of Tables XVIII and XIX.

It is thus seen that the percentage increment for both sexes is 

 very closely connected with the initial size. Whether there are 

 also minor differences related to the sex of the individual can not 

 be determined with certainty from the facts obtained. 



In order to find out more exactly the relation between food, 

 initial weight and percentage increment the weights of each piece 

 of beef taken by each of five males and five females (Tables XVIII 

 and XIX), respectively, for a period of four weeks out of the ten 

 were recorded. 



The following table shows the initial weights at the beginning 

 of the period of four weeks, the amount of beef taken during the 

 time and the percentage increments:
