Influence of Inanition on Metabolism. 



Table 146. Elements absorbed from food Metabolism experiment No. 76*. 



1 For March 12, 1905, the amounts of hydrogen and oxygen absorbed are 236.42 and 1804.39 

 grams respectively ; for March 13, 1905, the corresponding amounts are 239.44 and 1828.37 

 grams. 



Amounts of ingredients of food absorbed, and corresponding amounts of 

 body materials. A comparison of the protein, fat, and carbohydrates absorbed 

 from the food, obtained by the usual method, i. e., by deducting the quantities 

 of these compounds in the feces from those in the food, with the quantities 

 computed as body material absorbed is given in table 147. The data for all 

 days are identical.

x The amounts of water absorbed as calculated by the formulae were as follows: March 11, 

 1885.45 grams ; March 12, 1907.87 grams ; March 13, 1934.86 grams. 



Energy of material absorbed from food. The protein, fat, and carbohydrates 

 of the absorbed food when computed to the basis of body material yielded 

 for each day the following amounts of energy: From protein, 171 calories; 

 from fat, 732 calories; and from glycogen, 796 calories, a total of 1G99 calories. 

 The agreement of the energy thus computed with that determined from the 

 heat of combustion of the food and feces is perhaps as close as could be 

 expected, the error being approximately 1 per cent.
