It will be observed that there is not a preliminary experi- 

 ment for each metabolism experiment. The reason for this is 

 that the metabolism experiments following No. 14 were made 

 in series, with a preliminary period for the series rather than 

 for each experiment; that is, there was a preliminary diges- 

 tion period, after which the subject entered the respiration 

 calorimeter and remained there for nine to twelve da5^s consec- 

 utively, and this latter period was divided into two or more 

 metabolism experiments, each with its digestion experiment. 

 This explains why the total number of experiments for the cal- 

 orimeter period is larger than that for the preliminary period. 



Effect of confinement within the calorimeter upoyi availability . — 

 The averages of the results of experiments within the calorim- 

 eter are compared with those of experiments outside the calo- 

 rimeter in the table below. The rest experiments and the work 

 experiments are given separately for the different subjects.
