In this volume Dr. Horsley says about all there is to say on gastric surgery. The stage is set by brief chapters on embryology, anatomy and the physiology of the stomach, which are followed by detailed descriptions, well illustrated, of the various procedures. The reviewer is not competent to discuss the finer points of surgical technic. He does disagree, however, with some of the physiologic considerations which are supposed to furnish a rational basis for certain procedures. In his experience, for example, it is difficult to predict the results obtained by surgical intervention in cases of peptic ulcer. Sometimes the patient is helped; occasionally he is made worse. The effects are difficult to correlate with the mechanical changes which have been produced. The book is nicely gotten up, but the price is considered to be excessive.
