Calorimetric studies of basal metabolism have demonstrated that the human subject from infancy to old age eliminates a constant proportion, approximately 25 per cent, of the heat produced by basal metabolism in the vaporization of water through the skin and lungs.¹ Since water vapor forms under basal conditions a relatively fixed fraction of the total insensible perspiration (insensible loss of body weight) as measured with the balance, Benedict and Root² used the latter as a simple and practical method for predicting the basal metabolism of adults, and Levine, Wilson and Kelly³ subsequently applied this method of prediction to infants in the basal state. The procedure was next extended by Newburgh and his colleagues⁴ to estimations of the total heat production of adults under maintenance conditions over long periods. These workers⁵ soon modified their original procedure by utilizing the water vapor alone (H₂O) rather . . . [Full Text PDF of this Article]
