WEIGHT OF BOTH SUPEAEENALS IN THE CAPTIVE GEAYS 



Standards: Reference table 148 for Albino and table 206 

 for wild gray Norways. In both the Albino and the wild gray 

 Norway the weight of the suprarenals is much greater in 

 the female than in the male. 



In the wild strain the weights in both sexes are greater 

 than in the Albino. 



The percentage deviations in the weight of the suprarenals 

 (both glands) are given for the captive gray males in table 22 

 and for the females in table 23. The graphs for the devia- 

 tions on body length are entered in chart 20. Inspection of

Chart 20 Weight of suprarenals in captive Grays. Percentage deviations in 

 weight of suprarenals on body length, both sexes Albino standards. 



the graphs shows similar trends in the deviations for the two 

 sexes. The sag from G 6 to G 8 is very marked, but neglecting 

 this there is no tendency for a progressive diminution in the 

 weight of the suprarenals as between the earlier and later 

 generations.
