Recent studies seem to show conclusively that animals are influenced by temperature in the same way as plants. In the case of the crayfish, for example, the matter has been investigated with great care. The curve of activity of such an animal closely resembles that of plants, although of course the optimum temperature varies according to the species. The method of investigation consists in measuring the amount of oxygen consumed in a given time at a given temperature, or the amount of carbonic ...acid given off. Other chemical reactions of the body have also been exam- ined with similar results. The whole subject is in its infancy, but certain facts are already clear. The activity of an organism is closely related to the speed with which oxi- dation takes place, and the completeness and rapidity with which waste products are removed from the body. At low temperatures plants and cold-blooded animals cannot grow rapidly or be very active, simply because the various chemical processes of life cannot take place fast enough.
