While it is perfectly clear that it is in the metabolic pro- cesses of the body that we must seek for the final cause of the heat produced, it is incumbent on the physiologist to explain the remarkable fact that the mammalian body maintains, under a changing external temperature and other oliouti? conditions, and with a varying diet, during rest and labor, a temperature â nryvag within, usually, no more than a fraction of a degree centigrade. This we shall now endeavor to explain in part. Tkt Xtgnltliion of Ttmptnkare.âIt is manifest from the facts adduced that so long as life lasts heat is being of necessity constantly produced. If there wera no provision for getting rid of a portion of this heat, it is plain that the body would soon be consumed as effectually as if it wera placed in a furnace. We observe, however, that heat is being constantly lost by the breath, by perspiration (insensible), by conduction and radia- tion from the surface of the body, and periodically by the nrine and fseces. We have seen that, while heat is being pro- duced in all the tissues and organs o
