TABLE 49. Summary of experiments folloiving the ingestion of food. 



include 6 heavy-breakfast and 2 heavy-supper experiments. 



Statistical data for the subjects of the experiments following the 

 ingestion of food are given in table 51. In all there were 39 male 

 subjects, the average age for the period of experimenting ranging from 

 17 to 48 years. The large majority of the subjects were from 20 to 

 30 years of age. The average body- weight without clothing ranged 

 from 48 to 83 kilograms. The greater number of the subjects had a 

 body-weight between 55 and 65 kilograms. 



The experiments with each class of nutrients are discussed in separate 

 chapters in the following pages. In the tabulated results for the 

 calorimeter experiments, the amount, nitrogen content, and total 

 energy of the diet are given, also the fuel value, and the proportions of 

 energy from the different nutrients. The basal values for the carbon- 

 dioxide production, oxygen consumption, and heat production are 

 likewise recorded, together with the basal nitrogen in the urine of the 

 experimental day if this was obtained. Whenever the respiratory quo- 

 tients are given for the food periods, the basal, respiratory quotient,
