This is a most excellent book. It treats with fullness sufficient for all ordinary purposes of the physical diagnosis of diseases of the organs of the thoracic cavity. The descriptions of physical signs are clear and their explanation is well given. The few illustrations are of a useful character. A chapter is devoted to the sphygmograph and its relation to heart diseases. The fact that a second edition has been demanded shows that the profession has recognized its good qualitles. Although of a convenient size it deserves a more dignified title than that of a "pocket book."
