dioxide production was 73 grams, for oxygen consumption 30 grams, 

 and for heat production 107 calories. In the second experiment the 

 increase in carbon-dioxide excretion for the first four periods was 64 

 grams, for oxygen consumption 34 grams, and for heat production 116 

 calories. The nitrogen in the urine per 2 hours was very much greater 

 in this experiment than in the first, averaging 1.23 grams for the first 

 four periods as compared with 0.78 gram in the experiment of March 31 .
