Table 244. Comparison of computed and measured heat production, in metabolism 

 experiments with and without food Continued. 



Discrepancies such as appear in certain of the experiments between the 

 estimated energy of katabolized body material and the total heat production 

 may be caused by a number of factors. The assumptions involved in the com- 

 putations as used with the present form of apparatus are (1) that there are no 

 differences in the amounts of partially oxidized material in the body at the end 

 of each day; and (2) that the material in the urine represents the incompletely 

 oxidized nitrogenous fragment of the protein molecule. The influence of any
