This work is a pretentious volume of 729 pages without illustrations but well printed on excellent paper, which is fortunate, as every volume sold probably not only will be read but also will be kept on the purchaser's desk and used. It consists of eleven sections, one on each of the specialties, written in collaboration with the other members of the Faculty of Harvard Medical School. Each chapter aims to present such knowledge as the specialist thinks the general practitioner should possess concerning his field. The point of view is new, and it is surprising to note the difference between this work and the usual quiz compend or outline to help the student cram for examinations. The material here is carefully sorted, and only points of practical value are stressed. Therapy is discussed only in the conditions in which its management by the family physician would be safe and efficient.
