Last year Watts published in hard covers and larger size The Science Book of Wonder Drugs, by Donald G. Cooley. A paperback appeared simultaneously. The markets seemed not to overlap and both books had an excellent sale. Now the same experiment is being repeated with this new book, of which Pocket Books, in the Cardinal Edition, will be available at $.35. In the case of this book, however, the type face will be increased to a largersize, and there will be some drawings in two colors, as well as numerous line cuts and diagrams, by Kathleen Elgin. Oddly enough, there has been no recent, up-to-date physiology for the layman, based on late findings. The material is broken down into the usual sections:- the cardiovascular system, the blood and lymph, the respiratory system, the alimentary system, the liver, the urinary system, metabolism, the endocrine system, the male and female reproductive systems, pregnancy, the nervous system and the special senses, the musculo-skeletal system, the skin. The text is clear, concise, professional without being too technical. An excellent introduction, and the sort of basic reference book that should be in demand for a long time.
