This is a brief review of the subject of gastric and duodenal ulcer and contributes nothing that is new. Pathologic changes and theories of etiology occupy the greater portion of the first half of the book. The discussion is clear and, as the author intends, psychologic factors receive emphasis. The clinical discussion is inadequate. The pressing need of physicians today with regard to ulcer is the establishment of definite criteria for surgical intervention. Such indications cannot be listed in the conventional rote but require a general discussion well interlarded with clinical experience. The author states that gastric resection for duodenal ulcer is followed in many cases by hyperchlorhydria, a statement not borne out by the experience of any large surgical center. In general there is little in this treatise which cannot be found in the standard textbook of medicine.
