Influence of Inanition on Metabolism.

nitrogen per hour. At the time these determinations were made the computa- 

 tions of these rest experiments, in which very small amounts of nitrogen 

 existed in the cutaneous excretions, were so far advanced that to revise them 

 and allow for the nitrogen thus excreted would have involved a great amount 

 of labor. It was deemed inadvisable to incur the added expense of making 

 these changes and hence in all the experiments here reported no allowance 

 for the cutaneous excretion of nitrogenous material has been made. 



Elimination of Cabbon Dioxide and Absorption of Oxygen. 



The carbon dioxide and oxygen were determined during each 2-hour period 

 save for the preliminary night, when the periods were 3 hours long. The data 

 recorded in table 37 show the amounts in the chamber at the end of each 

 period, the carbon dioxide being expressed in grams and the oxygen in liters, 

 and also the total weight of both carbon dioxide exhaled and oxygen consumed 

 by the subject per period and daily. As has been pointed out before, these 

 data are sufficient for computing the proportion of either carbon dioxide or 

 oxygen in the air at any given period. 



The total amounts of both carbon dioxide and oxygen during the different 

 days of the experiment follow approximately the total amount of water-vapor 

 eliminated, i. e., on the second day of the experiment the largest amount of 

 water and carbon dioxide were exhaled and oxygen consumed, while on the first 

 and last days minimum amounts were observed.
