with the fundamental facts of health maintenance is especially commendable. Although the diseases discussed in this particular chapter, hy the very nature of this treatise, must be treated in only a fragmentary manner, the essential characteristics of such diseases as nephritis and diabetes are disclosed and the general regimen of treatment is indicated. Part 2 of the book treats entirely of community health. The fundamental concepts of infection and immunity, and the relationship of these t o communicable diseases are discussed. Of special interest in a text of this kind are the chapters on food control, water supply, waste disposal, and the admiuistration of public health to the various bureaus of state government. The final chapter of the book deals with disinfection and disinfectants. In this chapter the author elucidates the fundamental principles which underlie disinfection and discusses some of the commonly used disinfectants. It is unfortunate, however, that nothing is said about the more modem types of disinfectants such as the organic mereury compounds which ppossess a high germicidal value and are used extensively among the laity. To summarize, the author fulfils the purpose for which the hwk was written, that is, to present a general survey of personal health and its relation to the health of the community in its various ramifications. The style of the author is concise and easily comprehensible, and the text is free of typographical errors.

bished with new illustrations, and equipped with newly arranged tables of food data. The plan of the author is two-fold-first, to consider the food needs of the different members of a typical family, and second, to guide the housewife in filling these needs. It is in every sense a hook for the home, rather than a dietary guide for the institution or hospital. Two introductory chapters discuss briefly the chemistry of food and the physiology of digestion; then follow chapters treating of food for the adult man, the adult woman, the baby, children of various ages,.adalescent youth, and the adult after fifty. Other chapters present menus, the cast of food, food plans and dietaries, and faod for the sick. An appendix of a hundred pages contains extremely useful and well-arranged data, including a table on 100-calorie portions expressed in common household units. tables of vitamin values, etc. The data contained in this book are up to date. In vitamin tables, the old vitamin B is relaheled vitamin (B G), a tenhinology well recognized in America. A careful $istinction is drawn between the factors of growth and of maintenance; increased emphasis bas been placed on the daily use of foods which are sources of vitamins A and D, and of vitamins B and C for growing children. Nutritional saence today emphasizes a diet not merely for maintenance but a n optimum diet for higher mental and physical e5dency. Menus are arranged in the form of "a day's food plan"; the familiar calorie is retained as a unit, hut used only as a tool; the fetish of calorie counting is largely avoided.
