The author states in his preface that the "book has been prepared to aid the busy practitioner in the recognition, interpretation, and valuation of those outstanding signs and symptoms which, from the new viewpoint, are considered serious in chronic heart disease." In eighty pages of large type well spaced and with wide margins, the author attempts to give what he considers the newer aspects of cardiac enlargement, murmurs, aneurysm, hypertension, the various arrhythmias, and what is entitled the cardiac exhaustion syndrome, which includes angina pectoris, in a palatable and easily assimilable form. A practitioner should not be so busy that he cannot take time to know what he is doing and why he is doing it. It is doubtful, however, whether he would secure sufficient guidance from so brief and inadequate a treatise.
