Abstract

The recent method of Professor Magnus1 of Heidelberg in the study by registration of the intestinal movements has simplified the investigation of the action of agents on the intestine. Magnus names two kinds of periodic movements of the intestine: 1, the pendulum movements, which follow each other rapidly in a contraction and relaxation of the intestine; and, 2, a tonus variation, much slower, but making periodic changes in the intestine. Drs. Kubliabko2 and Alexandrowitsch, using the method of Magnus, have published a preliminary note on the action of several agents on the movements of the intestine.

Our experiments were made by taking a piece of the small intestine, about 10 centimeters in length, of a rabbit or cat. This was placed vertically in a glass containing 225 c.c. of the modified Ringer solution as advised by Magnus. One end of the intestine was fastened by a hook to an L-shaped glass tube and the other by a thread to Porter's heart lever, slightly weighted.
