A Note on the Composition of Human Sweat

Abstract

The CO2 content of sweat, especially acid sweat, was low. After removal of CO2 by boiling or aeration, alkaline sweat tended to become more alkaline; acid sweat usually showed no change in reaction. Such sweats apparently were acid because of components other than CO2, fatty acid, or P. The N and Cl content of arthritic sweat, the N content and reaction of sweat in psoriasis, and the reaction of sweat in sclero-derma and in nephritis showed no abnormalities. The N content of sweat in nephritis tended to be high. In psoriasis no sweating was observed over the involved areas.
