GASEOUS METABOLISM DUKING EEST.

not obtained until the latter part of October, but they may properly 

 be used here to indicate his metabohsm prior to dietetic restriction. 

 On the last 3 days of the experiment, the basal metabolism ranged 

 from a minimum of 1,217 calories with Pec and Tom to a maximum of 

 1 ,590 calories with Can. The average for the 1 1 men was 1 ,367 calories. 

 This represents a decrease of 319 calories or 19 per cent. Thus, by the 

 restriction of diet the total basal metabolism of this squad was actually 

 lowered 19 per cent.

ing the experiment, inasmuch 

 as Kon replaced Fre beginning 

 with the fourth night in the 

 large respiration chamber while 

 Spe was not included in the 

 group measurements after the 

 sixth experiment, it would be 

 illogical to compare the total 

 heat output of the whole squad 

 at the beginning and end of 

 the experiment from measure- 

 ments made with the group 

 respiration chamber. 



Heat Output per Kilogram of Body- 

 Weight WITH Low Diet, Squad A. 



As a means of comparing the 

 metabolism of different indi- 

 viduals or of the same individ- 

 uals under different conditions the heat per kilogram of body-weight 

 has been extensively used. The heat output computed on this basis 

 is recorded in the gaseous metabohsm tables for the individual sub- 

 jects. In table 129 the heat production per kilogram of body-weight 

 per 24 hours for the measurements nearest to October 1, November 

 24, and January 26 have been collected for the different subjects, 

 October 1 representing the beginning of the experiment, November 

 24 a period of strict reduction, and January 26 approximately the 

 end of the test. In obtaining these values, the method used has been 

 to average the measurements on two days either side of the date 

 here given, save in the case of October 1, for which all the values 

 measured previous to the restriction in diet have been used in the 

 average. Thus, for November 24 and January 26, the values for 5 

 days have, in general, been used. The values for Bro show a posi- 

 tive reduction in the heat production per kilogram of body-weight ; 

 with Can there was no appreciable change; with Kon there was a 

 slight increase, with Gar and Gul a regular decrease; with Mon a
