TABLE 239. A. L. L., February 16, 1906. Sitting. (2-hour periods.) 

 Heavy breakfast (mixed diet): 



Amount, 1,196 grams; nitrogen, 8 grams; total energy, 2,213 cals. 



Fuel value: Total, 2,142 cals.; from protein, 9 p. ct. ; from fat, 47 p. ct. ; from carbohydrates, 



44 p. ct. 



Nitrogen in urine, 0.90 gram per 2 hours. 

 Basal values (February 7 to 20, 1906) : CO2, 47 grams; Ch, 41 grams; heat, 151 cals. 



'Subject ate food in 20 minutes. 



103 grams graham bread, 25 grams cheese, 139 grams whole wheat 

 breakfast food (dry), 99 grams eggs, and 652 grams cream, a total of 

 1,779 grams. The fuel value was 4,378 calories, of which 12 per cent 

 came from protein, 56 per cent from fat, and 32 per cent from carbo- 

 hydrates. The data for the experiment given in table 240 show a 

 striking rise in the carbon-dioxide production, with similar increases in 

 the oxygen consumption and heat production, all of which continued 

 throughout the experiment, with no evidence of a return to basal value, 

 even in the last period. The total increment was 82 grams in carbon- 

 dioxide production, 65 grams in oxygen consumption, and 186 calories 

 in heat production. As the basal value for heat production was 568

32 p. ot. 



Nitrogen in urine, 1.63 grams per 2 hours. 

 Basal values (February 12 and 14, 1906) : CC>2, 45 grams; Oz, 40 grams; heat, 142 cals. 



Subject ate food in about 25 minutes.
