RELATION OF THE DUCTLESS GLANDS 151 



These views particularly the one referring to 

 adrenal function have been strenuously opposed 

 by Gley in France and Stewart in this country. 

 Professor Stewart's work will again be referred 

 to in a later chapter (see p. 165). Here it may be 

 said that he presented evidence to prove that adren-

aline is not essentially concerned in experimental 

 hyperglycemias (excess of sugar in the blood), 

 since hyperglycemia is obtained in rabbits which 

 have survived double adrenalectomy. It is con- 

 cluded that the mobilization of sugar, of which ex- 

 perimental hyperglycemias are an expression, is 

 not mediated through the secretion of the adren- 

 als.
