This constitutes the first part of a book which purports to take up in detail the subject of the normal and pathologic physiology of the muscular action of the gastro-intestinal canal.
The first chapter consists of a minute description of all the different methods used for the study of the subject. This is followed by a chapter on the voluntary and involuntary muscles of the intestinal canal and their innervations. Catel then takes up the physiology of the movements, starting with those of the mouth and following the muscular action through the entire intestinal tract, including the appendix and rectum. This is minutely described and thoroughly annotated. The author makes no attempt to cite all the publications on the subject but picks out those which seem to him most important.
The book is an exhaustive treatise by one who has spent many years in the study of the subject.
