Influence of Inanition on Metabolism. 



Balance of Energy. 



The comparison between the total heat production as measured and the 

 completed energy of katabolized body material is given in table 173. 



Table 173. Comparison of energy derived from katabolized body material ivith 

 total heat production Metabolism experiments Nos. 79-83, 85, and 89.

The average discrepancy for each experiment is as follows : Experiment No. 

 79, +5 calories or +0.3 per cent; for experiment No. 80, +23 calories or 

 +1.1 per cent; experiment No. 81, +2 calories or +0.1 per cent; experiment 

 No. 82, +28 calories or +1.2 per cent; experiment No. 83, 3 calories or 

 0.2 per cent; experiment No. 85, 12 calories or 0.5 per cent; experi- 

 ment No. 89, +39 calories or +1.8 per cent. Average of 7 experiments +12 

 calories or +0.5 per cent. 



Relations between Oxygen Consumption, Cabbon Dioxide Elimination, and Heat 



Production. 



The oxygen and carbon dioxide thermal quotients and the respiratory 

 quotients for experiments Nos. 79-83, 85, and 89 are shown in table 174.
