Physiology deals with the chemical and physical changes that occur in and by living matter. Vegetable physiology deals with plants, animal physiology with animals, human physiology with man. We cannot define ' life ' in physical terms ; we can, however, observe and state in what essential particulars living differs from non-living matter, or from matter that is dead. The essential feature of living matter is its instability ; it is the seat of chemical changes, collectively termed metabolism.^ These changes are divisible into—1. Constructive, integrative, anabolic, or synthetic processes, in the course of which non-living matter is annexed or assimilated by living matter ; 2.
