Variation in the activity of a cold-blooded animal is largely dependent \non metabolic changes, which in turn probably depend mainly on the accelleration \nof oxidation and of other chemical reactions. The physical \nnature of the environment affects most of these chemical processes, and \nwe should expect that the same physical properties would also directly \ninfluence the kinetic manifestations of animal life. While many observations \nrecord the qualitative relation of animal activity to such factors as \nhumidity and external temperature, only a few give definitive numerical \nresults.
