TABLE 221 J. J. C., May 9, 1910. Sitting. (1-hour periods.) 



Glidine: 1 



Amount, 45 grams; nitrogen, 6.24 grams; total energy, 223 cals. 



Fuel value: Total, 168 cals.; from protein, 95 p. ct.; from fat, 2 p. ct.; from carbohydrates, 



3 p. ct. 



Basal values: CO 2 , 24.5 grams (May 9, 1910); O 2 , 21 grams (March 4 to May 31, 1910); heat 

 (computed), 72 cals. (May 9, 1910). Nitrogen in urine, 0.26 gram per hour (May 

 9, 1910).

was considerable. As the basal values were determined on the same 

 day as the metabolism after glidine, there can be no uncertainty as to 

 the validity of the increments. 



TABLE 222. J. R., May 5, 1910. Sitting. (1-hour periods.) 

 Glidine: 1 



Amount, 70 grams; nitrogen, 9.70 grams; total energy, 347 cals. 



Fuel value: Total, 262 cals.; from protein, 95 p. ct.; from fat, 2 p. ct.; from carbohydrates, 



3 p. ct. 



Nitrogen in urine, 0.83 gram per hour. 



Basal values (May 5, 1910): COj, 27 grams; Oz, 23 grams; heat, 2 73 cals.; respiratory quotient 

 0.86. Nitrogen in urine, 0.44 gram per hour. 



*Taken in 200 grams of water. 



2 Heat eliminated corrected for change in body-weight, but not for change in body-temperature.

J. R., May 10, 1910. The same amount of glidine was taken in this 

 second experiment with J. R. as in that of May 5, and the results are 

 therefore comparable. Increments in the carbon-dioxide excretion, 

 oxygen consumption, and heat production were also found in this exper-
