Table LXI summarizes the most important statistics in the diary kept by the subject. The 

 subject •weighed himself with clothing twice each day. The reasons for not removing all the 

 clothing in Weighing were two: It was desirable to avoid the. muscular work involved in dressing 

 and undressing; it has also been found that the sudden increase of radiation of heat from the 

 skin when the clothing is removed causes a decided rise in the temperature inside the chamber, 

 and thus disturbs the accuracy of the heat measurements to some extent. There was extremely 

 little muscular exercise and no sensible perspiration. Hence the differences in weight from time 

 to time must represent very nearly the changes in body weight. The determinations of pulse 

 rate were made, of course, by the subject himself, when either sitting or reclining, after several 

 minutes rest. The measurement at 6.50 a. m., however, was made before rising from bed.
