Our previous studies and those reported by others have confirmed the constancy of basal measurements of the insensible perspiration by the method of weighings under standard conditions. The apparatus, the technical procedure, the sources of error and the reliability of the method have been discussed.1
The conditions that were accepted as standard in our previous studies prevailed in the experiments under discussion. They have been found to yield basal results. The conditions may be summarized as follows: (1) the subject awake but thoroughly relaxed and presenting no fluctuation in temperature throughout the experiment; (2) a small meal given at least two and one-half hours before the initial weighing, containing about 280 calories and having a fluid content of 150 cc.; (3) the clothing and bedding planned with an eye to having a minimum of hygroscopic materials; (4) a range in room temperature of from 18 to 25 C., in
