    CHAPTER II. THE MECHANICAL PHENOMENA OF ALIMENTATION (Continued). 6. The Movements of the Small Intestine.—A review of the literature on the movements of the intestine, both large and small, may be found in the articles of Grutzner x and Cannon 2 and in the section on the intestine by Starling 3 in Schaefer's Text-book of Physiology. The following para- graphs sum up Cannon's conclusions on the movements of the intestine as studied by the already outlined method of rr-ray examination of the alimentary tract after a meal mixed with bismuth subnitrate. Cats fed on canned salmon or bread-and-milk mush were used for experimental study. It is best to begin a description of the normal movements of the small intestine by referring to Fig. 4, in which is shown the appearance of the food in the intestine of a cat five and three-quarter hours after a meal of canned salmon. The animal is lying upon her back. In the middle of the plate in dim outline is seen the spinal cord with the pelvis below. On the right side above is the pyloric extremity of the stom- ach, and below it in dark shadow several intestinal loops lying over each other. In lighter outline and occupying the entire abdominal cavity are other loops also filled with food. The small dark shadow on the left is the caecum. 1 Grutzner: Pfliiger's Archiv, 1898, LXXI, p. 515. ?
