Influence or Inanition on Metabolism. 



and the quantities of water, protein, fat, and carbohydrates which were kata- 

 bolized in the body, as computed from the formulas, are recorded in the latter 

 part of the table. The katabolism of protein increased markedly on the 

 second and third days, and decreased on the fourth day. The katabolism of 

 fat increased on the second day, after which the amounts remained nearly 

 constant. The loss of glycogen is by far the largest on the first day, and is 



smallest on the fourth day. The amounts katabolized on the second and third 

 days were practically identical. 



Balance of water. According to the computations recorded in table 39, there 

 is a large loss of water to the body during each experimental day, but no

allowance has been made for the drinking-water and hence the actual loss to 

 the body of preformed water is less than that recorded in column e of table 39 

 by the amount of drinking-water consumed each day. Thus on the third 

 day, while there is an apparent loss of water from the body amounting to 

 1288.69 grams, the subject actually drank 1085.30 grams. Hence the actual 

 loss to the body for this particular day was but a little over 200 grams or only
