First published in 1980 as the second edition of a 1965 original, this book was extensively revised for this version, reflecting numerous advances in the area. Advice from specialists on various aspects of physiology was incorporated, resulting in a fresh appraisal of mammal physiology, especially in the fields of coordination and homeostatic mechanisms. The biochemical approach was extended and a much fuller treatment of reproduction was also included. This book will be of value to anyone with an interest in animal physiology.
