FOOD INGESTION AND ENERGY TRANSFORMATIONS. 



J. R., 8 h 49 m a. m. to 3 h 49 m p. m., March 21, 1910. 67.4 kilograms. 2 basal 

 periods. Took enema and urinated at 7 h 05 m a. m., also at 3 h 58 m p. m. Drank 

 68 grams water after eating. Basal periods: body-temperature, 37.50, 

 37.57, 37.63 C.; pulse rate, 70; respiration rate, 15. After food: body- 

 temperature, 37.75, 37.73, 37.74, 37.81, 37.93 C. ; pulse rate, 73; respiration 

 rate, 14. 



DISCUSSION OF EXPERIMENTS. 



OLIVE OIL (MAYONNAISE). 



The experiment with A. H. M., December 5 to 6, 1906, was fully 

 discussed in a previous section in which the basal metabolism was con- 

 sidered. Although originally planned for a 24-hour experiment, it was 

 soon apparent that the effect of ingesting oil could be found only by 

 studying the results obtained in the periods immediately following the 

 taking of the mayonnaise; hence the results of the experiment have 

 also been computed on both the 12-hour and the 8-hour basis. These 

 results are given in tables 19, 20, and 21. l From the figures given in 

 these tables, one may conclude that the effect of olive oil upon the 

 metabolism is slight. 



CREAM. 



A. L. L., March 27, 1906. This was the initial experiment of a series 

 in which the three subjects took essentially the same amount of cream. 

 The details of the experiment are given in table 184. In the 341 grams 

 of cream used only 5 per cent of the energy came from protein and 8

Cream: 



Amount, 341 grams; 2 nitrogen, 1.46 grams; total energy, 748 cals. 



Fuel value: Total, 735 cals.; from protein, 5 p. ct.; from fat, 87 p. ct.; from carbohydrates, 

 8 p. ct. 



Nitrogen in urine, 0.72 gram per 2 hours. 3 

 Basal values (April 3 and 6, 1906) : CO 2 , 47 grams; 0, 43 grams; heat, 145 cals. 



'See pp. 67 to 69. The results of the 24-hour experiment are given in table 14, p. 64. 



J Also 10 grams lime water and 253 grams water, a total of 604 grams. 



3 Sample included amount for about li hours without food preceding experiment.
