HOW TO LIVE LONGER

By J. R. Hayes, M.D. Philadelphia : J. B. Lippincott Co. Dr. Hayes, who is Medical Examiner to the Bureau of Pensions, has written at once a very sensible and a very readable hook. How sensible it is, any one who has any practical knowledge of dietetics and hygiene can see at a glance; and everybody will find it interesting. It resembles the talk of an exceedingly well informed and well-balanced physician, who points his advice with concrete illustrations and enlivens it with apt quotation. Some of his citations, indeed, show a rather remarkable eclecticism, inasmuch as they range from Pythagoras and Bichat and Browning to Dr. T. De Vitt Talmage and Mrs. Frank Leslie; but this is a minor detail. If the average man would only read this book and remember its very plain and simple suggestions, he would presently become more cheerful in mind, more healthy in body, and better assured of a longer and more useful life.
