Metabolism of Healthy Man. 



IN EXPERIMENTS WITH FOOD. 



In table 47 the observations of the body-temperature with the rectal ther- 

 mometer in experiments with food have been collected. The results of experi- 

 ments with 8 different subjects are here given for a total of 21 days of 24 

 hours each. The number of observations per day is shown to have varied 

 from 8 to 25, and in the last column of the table is recorded the average tem- 

 perature. Deferring for the moment the discussion of the time of the minimum 

 and maximum temperatures and of the range for the day, it is seen that the 

 average temperature of these men was 36.82 C. (98.3 F.).

 IN EXPERIMENTS WITHOUT FOOD. 



Body-temperature in experiments without food has been given previous treat- 

 ment, 1 but the results are here collected for comparison. The data for 11 sub-
