Influence of Inanition on Metabolism. 



includes water of food as well as water of drink. In all other respects, the 

 table is identical with preceding ones of this type. 



The income of water consists of the water in food and drink. The total 

 outgo of water is the sum of the amounts in the urine, respiration and perspi- 

 ration, and feces. On the third day, for example (the only day on which feces 

 were passed), there was an intake of water consisting of 1255.28 grams in the 

 food (see table 56) and 344.00 grams of drinking-water (see table 45). On 

 that day there were eliminated 586.16 grams of water in the urine (see table 

 47), 1059.07 grams of water of respiration and perspiration, 79.1 grams of 

 water in the feces (see footnote, table 63), making the total elimination for 

 the day 1724.33 grams.

1 Includes 79.1 grams water of feces passed on this day. In obtaining this amount it is 

 assumed that water existed in the feces passed on this day in the same proportion that it did 

 in the total feces of the experiment. 



2 Gain. 



These figures for the intake and outgo indicate an apparent loss to the 

 body of 125.05 grams of water. The preformed water, however, alone repre- 

 sents the actual gain or loss of water to the body, the water of oxidation of 

 organic hydrogen (column g, table 63) not being taken into the body as water. 

 On this particular day the body gained 149.57 grams of preformed water 

 (column f, table 63). 



Nutrients, ash, and energy. The balances for the materials and energy 

 indicated under this head are shown in table 64. 



Protein. On comparing the protein katabolised (table 51) with the amounts 

 of protein computed in terms of body protein as having been absorbed from 

 the food a noticeable loss in protein is observed not only on the first but also 

 on the two remaining days of the experiment. The average loss was 16.8 grams. 

 The fact that there is a loss on all three days indicates that the food consumed
