This volume is one of several edited by Dr. Case. Its intrinsic value rests solely in the presentation of a large number of beautiful reproductions of roentgenograms mostly from the author's own experience, a few from others. An historical review of the development of the recognition of the various lesions encountered in roentgenography of the stomach and duodenum tract is well presented. The importance of careful examination of the patient in various positions and at various angles is stressed. An abstract of most of the cases accompanies the illustrations. This book can be especially recommended as an illustrated guide for beginners.
