This new textbook of physiology is edited by Houssay, well-known endocrinologist and Nobel laureate in physiology, and written by him and other South American physiologists. It gives a well-balanced presentation of the various parts of human physiology, without undue overemphasis of those areas of physiological research in which the writers are particularly interested. The book will be of great value to beginning medical students who find other standard textbooks too difficult. The book is amply illustrated, and each chapter is provided with a small number of additional references for further study. There is an extensive index. Printing and binding are excellent.
