HUMAN POWER. By Clement Jeffery. (Mills and Boon. 7s. 6d.)—The

reader will agree with almost everything the author has written, except the title, which remains a mystery to the end. " Commonsense Ideas about Health " or " Per- sonal Hygiene " are titles which more suitably express the contents and purpose of this hook. A querulous reader (especially if he was a registered medical practitioner) might find cause for complaint in the implied infallibility of the bonesetter, and in some nonsense which is talked about the acidity of the blood. Apart from these occasional interruptions to the main theme, the book gives a straightforward and sensible account of how to keep healthy and is addressed to that growing audience which seeks to learn more about the laws of health.
