The first part of the volume deals with the development of the technic of gastrography by Porges and Heilpern, the special technic employed in the present investigation, precautions to be observed, and untoward reactions in the patients. Then follows a description of the appearance of the different regions of the normal stomach accessible to photography, amply illustrated. The remainder deals with the photographic appearance of the gastric mucosa in ulcerative gastritis, gastric cancer, gastritis, pernicious anemia, benign gastric tumors, gastric resections and gastro-enterostomy, all well illustrated with photographs arranged for stereoscopic vision. All photographs are attached to the pages so that they can easily be detached and placed in the stereoscope. The material is clearly presented. The monograph is modest in its claims for gastro-photography, both as to diagnosis and as to research.
