This little treatise attempts to present in simple terms the problems of urology which confront the general physician. Special problems of surgical technic and the like are not gone into. The discussions are brief and simple and to the reviewer seem useful. For example, a chapter on "catheters and sounds—their uses and dangers" can surely be read with profit. Some of the material on medical problems, such as nephritis, is sketchy and perhaps less useful. The book is well illustrated and has an index.
