WEIGHT OP GONADS IN THE CAPTIVE GRAYS 



Standards: Reference table 146 for the Albino and table 

 207 for the wild gray Norway. In both sexes the gonads in 

 the wild gray Norway are heavier than in the Albino. 



The percentage deviations in the weights of the gonads, 

 on albino standards, are given in table 24. The correspond- 

 ing graphs, on body length, are entered in chart 21.

The records do not begin until G 4 . As shown in chart Jl. 

 the graphs for the two sexes exhibit the same trends, save at 

 G 5 . This suggests that the influences affecting the weight of 

 the gonads act in a similar manner in both sexes.
