Abstract
THE maintenance of relatively constant internal conditions in the face of a fluctuating external environment is perhaps the most characteristic feature of living, as opposed to non-living, systems. Such constancy, however, is only achieved and maintained by active regulatory processes on the part of the animal itself, and an animal only survives in so far as its 'physiological regulations' are competent to oppose and nullify any threatened change in its internal state. All physiological processes, with the exception of reproduction, appear, in the long run, to be devoted to this end ; and the physiologist has come-to define life as a perfectly integrated series of physiological regulations.
