increased sugar tolerance would lead to an excess of fat such as is observed 

 in dystropjiia adiposogenitalis. In most of the experiments the conclu- 

 sions have been drawn after feeding patients or experimental animals sugar 

 by mouth. The most accurate studies would naturally be made in those 

 experiments in which known amounts of sugar were given intravenously. 



The glycosuria which accompanies hypophyseal operations is light and 

 transitory, disappearing in from 24 to 36 hours after the operation. 



Camus and Koussy came to the following conclusions concerning 

 glycosuria : 



(a) The different interventions practiced upon the pituitary body, 

 partial removal of one or both lobes or total removal do not modify in an 

 appreciable degree the tolerance to carbohydrates nor the appearance of ali- 

 mentary glycosuria. 



(b) The injections of concentrated extracts of the posterior lobe, the 

 anterior lobe or of the whole hypophysis do not sensibly modify in the 

 animals operated on the limit of tolerance to carbohydrates.
