Although our knowledge of the thermogenic mechanism is still in a formative state, we nevertheless have sufficient experimental data to warrant the conclusion that in the higher animals the heat formed arises in part as a product incident to the activities of all forms of vital processes, and in part as a specific product of specific heat-producing structures. The results of Rubner's researches leave no doubt as to the skeletal muscles possessing, besides their motorial properties, a specific thermogenic function, and, as a consequence, that these structures not only produce heat as an incident to repair, growth and motor activity, but also as a specific product. They further show that the quantity of heat which arises by virtue of this special function bears a reciprocal relationship to the amount formed as an incident to the activities of the body structures generally, increasing or decreasing in adjustment to the variations in
