The second volume of the second section of the Handbook of Physiology, edited by W. F. Hamilton and P. Dow for the American Physiological Society, is a comprehensive resource on the functional characteristics of blood vessels and their coordination in supplying blood to various organs. This volume, priced at £12. 16s., is justifiable for experts in the field as it provides a summary of current knowledge rather than the latest research findings. The book includes contributions from authors around the world, with notable chapters on the circulation in skeletal muscle and skin, as well as on the regulation of circulation in the lung, heart, kidney, and liver. Chapters on vascular diseases, arteriovenous pathways, lymph, the venous system, and capillary exchange are also included. The volume is a significant contribution to physiology and is highly recommended for physiologists. "An Outline of Bacteriology and Immunity," by Ronald Hare, M.D., is a second edition of a popular textbook that covers all essential information for medical students. It includes new sections on bacterial genetics and routine immunization, along with updated chapters on fungi, rickettsiae, viruses, and bacteriophages. The book goes beyond being a textbook for examinations, offering valuable information throughout a medical career. Sections on immunization, infection sources and transmission, chemotherapy, and sterilization methods are particularly useful. The book is well-illustrated with tables and figures and is highly recommended for medical students.The second volume of the second section of the Handbook of Physiology, edited by W. F.
