Influence of Inanition on Metabolism. 



Table 177. Amounts of determined, nitrogen, protein, phosphorus, sulphur, and 



energy in food Continued. 



Comparison of calculated and determined amounts of protein and energy of 

 food. For reasons which will appear later, it seemed desirable to obtain some 

 check upon the analytical work connected with the determination of nitrogen, 

 and also upon the heats of combustion determined by the bomb calorimeter. 

 The calculated protein and energy shown in table 176 were obtained primarily 

 for this purpose. In table 178 the comparison of the calculated with the 

 determined results is shown. It should be stated, however, that the unusual 

 care taken in the preparation and analysis of these samples renders the 

 comparison a test of the accuracy of the average figures rather than a check 

 on the analyses. The comparison is nevertheless not without interest and 

 it is accordingly here presented.
