FOOD INGESTION AND ENERGY TRANSFORMATIONS. 



Inasmuch as a considerable number of the calorimeter experiments 

 continued for 8 or more hours and hence represent a fairly long period 

 of time when the metabolism was measured, and, indeed, usually a much 

 longer period than that represented by the respiration experiments, the 

 data for the two classes of experiments are given separately, those for 

 the calorimeter experiments being included in table 249 and those for 

 the respiration experiments in table 250. We have, furthermore, 



TABLE 250. Cost of digestion of various food materials, respiration experiments.
