5O CHESTER A. STEWART. 



eyeballs, spinal cord, alimentary canal, hypophysis, testes and 

 suprarenals have in general decreased in (relative) weight so 

 as to approach the normal within the first four weeks of refeeding. 

 The testes and the suprarenals may even become subnormal in 

 weight during the first four weeks of refeeding, but all are prac- 

 tically normal in the rats refed to the adult condition. 



The pineal body was approximately normal in weight in the 

 test rats refed four weeks, and in the adult test animals. There 

 was no evidence of a sexual difference in the weight of the pineal 

 body in rats of corresponding body weight.
