Influence of Inanition on Metabolism. 



Elimination of Wateb-Vapob. 

 The total water of respiration and perspiration is tabulated in table 48. 

 Contrary to the results usually obtained in fasting experiments, there is an 

 increase from one day to another in the water eliminated. The relative 

 humidity may be obtained by the method previously explained.

experiment No. 70. 



1 Allowance has been made for water gained by the chair, bedding, and miscellaneous 

 articles as follows : December 20-21. 5.26 grams ; December 21-22, 30.22 grams ; December 

 22-23, 43.32 grams. (See p. 61.) 



Elimination of Cabbon Dioxide and Absoeption of Oxygen. 



The data indicated by this heading are reported in table 49. The continual 

 daily increase in the amounts is noticeable. 



Material Jcatabolized in tlie body. Although food as well as water was 

 ingested in this experiment, the computations by which the materials kata- 

 bolized are obtained are in no wise different from those in experiments without 

 food. The reason for this method of computation will appear from a con- 

 sideration of the status of water drunk in fasting experiments. As has already 

 been explained, in the latter type of experiment the computations omit water 

 from the intake because only the oxygen is capable of entering into chemical
