DISCUSSION OF RESULTS OF WATER-DRINKING EXPERIMENTS. 



Of special significance is the fact that in the three Boston calorimeter 

 experiments the heat output as reported is heat eliminated and not 

 heat produced ; that is, the heat measurements have not been corrected 

 for changes in the body- temperature. From an inspection of the data 

 giving the increments in the water-drinking periods, it will be seen 

 that in most cases the gaseous metabolism shows a positive increase 

 corresponding to the increase in the heat output and in some instances 

 it is roughly proportional to the increase in the heat. This, to a certain 

 degree, confirms the validity of the heat measurements, even when not 

 corrected for changes in the body-temperature. 



In the final summaries, given in tables 67 and 68 (see pages 135 and 136) , 

 the total increments and the percentage increments are based solely 

 upon the heat measurements. The values in table 67 show that in 

 all but one of the calorimeter experiments, that with A. W. W. on 

 March 27, 1907, there was a positive increase in the heat output as 

 a result of taking water. In only two of the calorimeter experi- 

 ments, those of January 13, 1911, with J. J. C., and January 12, 1911, 

 with T. M. C., can the increments be considered as really significant,
