Influence of pituitrin and of adrenalin on the pupil of normal and 

 ganglionectomized rabbits. A demonstration. 



[From the Department of Physiology and Pharmacology of the 

 Rockefeller Institute for Medical Reserch, New York.] 



By T. S. Githens and S. J. Meltzer.

 the body in the same direction. The most striking action is the 

 production of a blood pressure rise by both substances. The 

 action of both substances upon the uterus and upon the intestines 



This gain was made on addition of 2 grains of v»tamine per day.
