Cream: 



Amount, 345 grams; 1 nitrogen, 1.44 grams; total energy, 779 cals. 



Fuel value: Total, 766 cals.; from protein, 5 p. ct. ; from fat, 87 p. ct. ; from carbohydrates 



8 p. ct. 

 Baaal values (February 12 and 14, 1906) : CO:, 45 grams; O 2 , 40 grams; heat, 142 cals. 



J. J. C., March 22, 1910. The details of the first experiment in 

 Boston with cream are given in table 187. A larger amount of cream 

 was taken by this subject than by the subjects of the Middletown 

 experiments, the amount being 445 grams. In the first hour no incre- 

 ment was obtained for any one of the three factors. Slight increases 

 in the carbon-dioxide production and oxygen consumption were observed 

 in the 3 following hours but the values for heat production were invari- 

 ably below the basal value. There was a slight increase in the pulse 

 rate during the two middle periods. At first sight these results would
