ments. All of the factors indicate a considerable increase in the actual 

 metabolic processes.

H. R. D., March 31, 1906. (1,173 grams bananas and 103 grams 

 sugar, with a total fuel value of 1,562 calories). The data given in 

 table 111 show large increases in the carbon-dioxide excretion over the 

 basal value in the first three periods. There was a concordant increase 

 in the oxygen consumption and an increment in the heat production. 

 We thus have here practically the same picture with all three factors 

 of metabolism, indicating an increased metabolism following the inges- 

 tion of bananas and sugar.
