case, a cat, there was with one eighth of a drop an increase ol tonus 

 and a slight augmentation of peristalsis. In the balloon method, 

 bile given per jugular or injected into the lumen of the intestinal 

 part experimented upon decreased peristalsis. In the rabbit, with 

 one eighth of a drop by the Magnus method a temporary, well 

 marked inhibition of peristalsis was seen with a decrease of extent 

 of peristalsis. In a cat by the balloon method, one half a drop 

 per jugular increased peristalsis. In a rabbit, one quarter of a 

 drop by the jugular produced an increased peristalsis with the 

 balloon method. 



Effect of bile on the large intestine. — The effect of bile on the 

 large intestine by the Magnus method was to decrease tonus and 

 peristalsis of the intestine. In rabbits there was occasionally, 

 after a Jg to a -^^ of a drop of bile by the Magnus method, greatly 

 increased peristalsis. In the balloon method, bile in the cat per 

 jugular in doses of a drop, decreased tonus and peristalsis at first, 

 and afterwards greatly increased them. 



Effect of glycocholic acid upon the small intestitie. — In the cat, 

 by the balloon method, three quarters of a grain of glycocholic 

 acid per jugular increased the tonus and the extent of the per- 

 istaltic movements. In other cats, one half grain of glycocholic 

 acid decreased peristalsis, using the balloon method and injecting 

 the acid per jugular. 



In the rabbit, y^-g- of a grain of glycocholic acid by the Magnus 

 method greatly decreased the tonus and peristalsis. 



Effect of glycocholic acid upon the large intestine. — In the 

 rabbit, glycocholic acid by the balloon method in one half grain 

 doses per jugular decreased peristalsis. In a rabbit and a cat it 

 increased peristalsis producing quite large waves. 



Effect of taurocholic acid on the small intestine. — In the cat, 

 one half grain of taurocholic acid greatly increased peristalsis by 

 the Magnus method. In the rabbit there was a momentary in- 

 crease of tonus by the Magnus method. 



In the rabbit, witli Jg to \ grain of taurocholic acid there was 

 with the Magnus method a great decrease of tonus and peris- 

 talsis. 



In the balloon method, | of a grain of taurocholic acid per 

 jugular in the cat increased peristalsis after a temporary decrease.
