Published in the same year as the first penicillin therapies, this short introductory text to physiology is now dated in diverse and amusing ways. In some fields little has changed - the legs still branch off the head, the heart is in the knees, etc. - but in others there has been so much change between then and now that it is hard to appreciate. Neuroanatomy, neurology, endocrinology, molecular biology - the entire field of genetics has been re-written - the list goes on. In knowledge of systems, diseases and most dramatically in treatments, medical technology has changed incredibly. If I were to return to 1942 and explain the things now known to the author he would ask how much I'd been drinking.
Recommended to those with an interest in medical history, or curious to see the changes in approach since 1942 to all things physiological and to a lesser extent medical.
