First and only edition of this early American dissertation submitted to the trustees of Columbia College, in the state of New York, for the degree of Doctor of Physic. Walker gives an in-depth analysis of the physiology, pathology and chemical actions that produce perspiration, as well as describing various secretions and how they originate. In addition, there is a discussion on both the benefits and damages sweating can do to the body. Of particular interest are his ideas on odors in relation to uncleanliness and skin colour, and how they can cause malignant and pestilential disease.
