This is on the whole a well written textbook of physiology intended for graduate and medical students. Dr. Martin, senior author, is known not only for his many important researches in physiology but also for his revision of the old classic, Martin's "Human Body." The subject of physiology is treated under four main headings.
Part 1, the nature and capacities of protoplasm, is written by Dr. Martin. There are nine chapters of 154 pages which deal with cell organization, cell membranes, chemistry of life processes, conduction, reflex action and gland function.
Part 2 also written by Dr. Martin, has as a general heading cell environment. It consists of five chapters, on regulation of neutrality, on inorganic salts, vitamins, hormones and oxygen.
Part 3, by Dr. Martin, under the heading, body maintenance, includes fifteen chapters, dealing mainly with the physiology of the blood, circulation, respiration, digestion, secretion and metabolism.
