The action of bile and some of its constituents upon intestinal 

 peristalsis and the circulation. 



By ISAAC OTT and JOHN C. SCOTT. 



\Froni the Laboratory of the Medico-Chirurgical College of 

 Philadelphia?^ 



In their experiments with a Vella fi.stula, Fubini and Luzzati 

 found that a pea, fastened to a thread, passed along the bowel 

 more quickly when ten to fifteen minutes previously they had in- 

 jected two grams of bile. C. Eckhard,^ of Giessen, also studied 

 the influence of the bile upon the peristaltic movement of the 

 small intestine. 



Eckhard experimented upon rabbits. He used a sodium chloride 

 bath and studied the movements of the intestine in situ after opening 

 the abdomen. After the injection into the duodenum of one cubic 

 centimeter of bile of the rabbit the duodenum remained for ten 

 minutes in absolute rest. He injected three c.c. of bile of rabbit, 

 calf and sheep in different parts of the small intestine with the
