DISCUSSION OF EXPERIMENTS. 



L. E. E., May 3, 1910. The subject took 45 grams of glidine sus- 

 pended in 110 grams of water, with a nitrogen content of 6.24 grams; 

 the results obtained are given in table 219. The basal value was found 

 on the same day, immediately prior to the ingestion of the glidine. A 

 marked increment in carbon-dioxide production and oxygen consump- 

 tion was noted in all the periods of the experiment and an increase in 

 heat production in the first two periods; in the last two periods the 

 values for the heat production were within 1 calorie of the basal value.

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



L. E. E., May 11, 1910. The same amount of glidine was taken as 

 in the first experiment with this subject; the basal value was determined 

 immediately before the observations with glidine. The results are 

 given in table 220. Noticeable increments in the carbon-dioxide pro- 

 duction and oxygen consumption were obtained in the three 1-hour 

 periods, but relatively insignificant increments were found in the heat 

 production. The absence of body-temperature measurements, with the
