The elimination of heat from the body is dependent almost entirely on radiation, conduction and evaporation. While it is possible to determine the sum total of heat loss of an individual, the accurate determination of the parts entering into this sum is beset with difficulties which have not as yet been surmounted. Nevertheless, even relatively simple methods can yield some information, if not of the amount of heat lost by one or the other mechanism, at least about some of the conditions exercising an influence thereon. Thus, a study of the surface temperature gave us some data1—more accurate than available before — concerning the heat loss by conduction and radiation. In this communication we wish to report data with regard to the evaporation of water from the body surface other than the loss of water through lungs and sweat, that is, the so-called insensible perspiration.
