Abstract
Three types of movement were observed to occur during the normal intestinal movements of a rabbit by means of a glass abdominal window. The frequency of the appearance of each type of movement is controlled by the volume of intestinal content. When a large quantity of fodder taken is moderate, the rhythmic segmentation set out more than half. While a small quantity provokes the pendular movement. The above conclusions are not only affected by the kind of fodder, but by substitutes of isotonic solutions for fodder. We could demonstrate these findings by an in vitro experiment using an excised intestine connected in a circle.
