This book is a manual of medical diagnosis from a clinical standpoint and is generally well written, but there is an occasional lapse. On page 110, the following title arrests attention: "The Chemical Analysis of the Stomach as a Means of Diagnosing Gastric Disturbances." On reading the text it is seen that it is the contents of the stomach, that are to be analyzed, and not that organ itself as the title states. The table on bacteriologic diagnosis is excellent, but the directions for demonstrating the presence of bacteria in specimens, is not given at that place but scattered through the volume. The typography is singularly unattractive, but there is much useful information in the work— a jewel which deserves a better setting.
