In any study of water loss from the human body it is necessary to measure that which leaves the respiratory system. Methods have been described, but they are either inaccurate or cumbersome. It is beyond the scope of this paper to review the methods used in the past to measure the water loss through the pulmonary system; many of these are referred to in several excellent discussions on insensible perspiration.¹ Galeotti and his associates² and Weyrich³ used bottles of sulfuric acid or calcium chloride to trap the expired water and measure gravimetrically the water collected. These are not simple procedures, and their accuracy is not well established. The observers did not control the conditions of the air inspired. The paper by Galeotti and Signorelli^2a included a review of some of the early methods used to measure expired water. Loewy and Gerhartz⁴ measured the temperature of . . .
