U. S. PAT. OFF, CALCIUM CHLORIDE A MODERN PHILOSOPHY OF PHYSICAL EDUCATION. By Agnes R. Wayman. Pp. 231. Illustrated—pho- tographs and diagrams. Philadelphia: W. B. Saunders Company, 1938. $2.25. HE book suggests that a point of view and a philosophy is neces- sary for the teacher to use intelligently the material available in the field of health and physical education. Also, how to use that materal in the light a changing social and educational pKil- osophy. Although written with special implications for girls and womén, this book is applicable to all (male and fe- male) situations, scholastic, or club work. Part 1 presents the underlying phil- osophy and principles, beginning with significant social trends, in the chang- ing world. Today, we live in a “tuned up” and “wound up” world, which carries both good and bad significance. Physical education has become one of the balance wheels of civilization, and must see its problems in relation to the society in which we live. The emphasis in education has shifted from subject matter to the individual. In physical education, where once the emphasis was on the values of the field as a therapeutic agent, it is now on the broader implications of education. The by-products of activity, such as hab- its, appreciations and attitudes, have become more important than that of skills. Part 2 concerns itself with implica- tions and interpretations. The program should measure up to certain definite criteria and be built upon the needs of the individual, as indicated by tests, measurements, examinations, ques- tionnaires, and student conferences. We can have progress only as we have measurement and profit by it. There is a very definite trend away from team games and toward activities which the student can use in leisure time. The final criterion of a program is that it fills the needs of the students for which it is intended. HYMAN KRAKOWER IMMING POOL DATA & REF- CE ANNUAL (Vol. 6, 1938). Ed- ed by Earl K. Collins.

The book is illustrated profusely w ATHLETIC INJURIES tion, Diagnosis and Treatment). By Augustus Thorndike, Jr., M.D. Pp. 208. Illustrated — photographs and draw- ings. Philadelphia: Lea & Febiger. $3. R. THORNDIKE has been a sur- geon in the department of hy- giene at Harvard University for the past six years. In his book, he presents as clearly and concisely as possible the problem of prevention, diagnosis and treatment of injuries received in sport. The finished product merits a place on the sports shelf of every trainer, coach and athlete. It is exceptionally well written and illustrated, dealing almost exclusively with athletic injuries and treatment including protective ban- daging, taping, braces, etc. The book has been arranged in three sections: the first, dealing with the pre- vention of injuries and the factors in- cident to this; the second, the types of injuries received in sport and their pathological nature; and third, the more common injuries occurring in va- rious parts of the body and their diag- nosis and treatment. The type and organization of the il- lustrations are excellent. Many of the more common athletic injuries are shown in photographs and often sup- plemented by roentgen-ray (X-ray) pictures of the injury. For follow-up work, the text contains a group of drawings which show graphically how to bandage injuries. It is a simple mat- ter to follow the method of bandaging since each strip of tape is numbered in sequence. Included are several of the bandages made famous by such men as “Duke” Simpson, Major Frank Wan- dle of Yale and J. M. Cox of Harvard. In a chapter on physical training, Dr. Thorndike lists what he believes to be the four main features of such a course: diet, sleep, graduated muscular exercise and the absence of all drugs. He has found that a diet of 5,000 to 6,000 calories is necessary in football and crew and somewhat less for other sports like track, baseball and hockey. It is interesting also to observe that the Doctor subscribes to the theory that certain athletes are “born” and that others are not. He attributes this to the fact that these athletes have a better coordinating mechanism, particularly in the control, voluntary as well as re- flex, of the central nervous system over muscular activity. He does not believe in the so-called “athlete’s heart’ for the reason that the athlete’s heart is increased in size and musculature directly in propor- tion to the size of his skeletal muscles. sis a il a a iS Saad
