discussion elsewhere, it will suffice for the particular purpose in view to give 

 the body temperature determinations for the end of each period. These are 

 recorded in column a of table 16. The differences from period to period are 

 recorded in the second column. The data recording the body-weight are given 

 in columns c and d, while the final column gives the differences, due to changes 

 in body-weight and temperature, in the amount of heat stored in the body. 



Table 17. Total heat production Metabolism experiment No. 59. 



In order to show the method by which the chauge in the amount of heat 

 stored in the body of the subject (column e) is found, a concrete example is 

 here taken. At 7 a. m., December 18, the subject weighed 67.796 kilos, the body 

 temperature was 36.72, and the calorimeter temperature was 20. If his body 

 had cooled down to the calorimeter temperature immediately, the quantity of 

 heat which would have been liberated would be 67.796 X 0.83 (the specific 

 heat of body material) X 16.72 (difference between the temperature of the
