Influence of Inanition on Metabolism. 



Balance of water. In table 100, showing the distribution of intake and 

 output of water, the results are obtained as explained earlier in tins publica- 

 tion. Allowance has not been made in columns d and /, however, for water of 

 feces passed on the first 3 days of the experiment for the reason explained in 

 the discussion of table 73, page 120. 



Tbe data below show that the actual loss of water to the body was very 

 much less than the apparent loss shown in table 99. The water of oxidation 

 of organic hydrogen is not materially different in amount from that found in 

 the previous fasting experiments.

1 Does not include water of feces, 

 periment only. 



Feces were passed on the first three days of the ex- 



Changes in Body-Weight Compared with Balance of Income and Outgo. 



The subject was weighed as usual each morning throughout the experiment 

 and in table 101 a comparison of the changes in body-weight with the balance 

 of income and outgo is given. The income consists of water and oxygen 

 consumed while the outgo includes the urine, feces, carbon dioxide, and water 

 of respiration and perspiration. 



Before the fasting period began the subject took a gelatin capsule filled with 

 lampblack. Feces were passed the first 3 days of the experiment in the follow- 

 ing amounts: First day, 71.60 grams; second day, 87 grams; and the third 

 day, 51.10 grams, but as they contained no lampblack they undoubtedly 

 resulted from the food consumed before the fast. In making the balance of 

 income and outgo, however, the feces have in effect been restored to the body 

 of the subject, and the losses shown by the scale have been correspondingly 

 reduced.
