and recorded in columns c, d, and e of table 14, are not shown, but the results 

 of these corrections to the heat eliminated are combined with the correction due 

 to changes of body temperature and body-weight. This latter correction 

 (shown for experiment No. 59 in column b of table 17) is not given separate 

 treatment in this and subsequent experiments. The net results of all these 

 corrections are shown in column c of table 30. 



The heat not measured by the water-current, due to the vaporization of 

 water, was found in experiment No. 59 by multiplying the water vaporized by 

 0.592. In that experiment the figures given in column f, table 14, were 

 identical with the figures given in column e of table 5; that is, the water

vaporized and the total water of respiration and perspiration were identical. 

 This arose from the fact that in that experiment no correction was made 

 for changes in moisture content of articles inside the calorimeter, as data 

 upon this subject were lacking. In this experiment, however, it should be noted 

 that the heat used in vaporization of water shown in column b of table 30 is 

 obtained not by multiplying the total water of respiration and perspiration 

 shown in column b of table 24 by 0.592, but by applying this factor to the 

 total amount of water vaporized, since the heat correction has to do not with 

 water of respiration and perspiration but with water actually vaporized in the 

 chamber during the period. So far as the heat measurements are concerned, 

 it is immaterial whether the water be vaporized from the surface of the man or 

 the bed-clothing or elsewhere inside the chamber. On the other hand, a true 

 measure of water of respiration and perspiration from the body of the subject 

 for each period should make due allowance for changes in water content of the 

 various articles in the chamber.
