DISCUSSION OF RESULTS AND GENERAL CONCLUSIONS.

the respiration apparatus is fully in conformity with the increased metabolism 

 noted with normal individuals when changing from a lying to a sitting position. 1 

 In the later investigation the subdivision of experiments is almost exclu- 

 sively between the bed calorimeter and the respiration apparatus, there being 

 but one set of experiments made with the chair calorimeter. The results for 

 all the cases are given in table 120. Special attention is drawn to the average 

 carbon-dioxide excretion of the severe cases. Unlike the results given in the 

 earlier report, the experiments with the bed calorimeter apparently show a con- 

 siderably higher average value than does the respiration apparatus, i. e., 3.G4 

 c.c. against 3.24 c.c. A close inspection of the figures shows, however, that the 

 value for the bed calorimeter is distinctly affected by the abnormally high 

 values of Cases I and N. It is also due to the fact that in practically no case

were experiments made simultaneously with the bed calorimeter and the respi- 

 ration apparatus. The only exception to this is Case U, where the value of 3.88 

 c.c. with the bed calorimeter does not differ widely from that found with the 

 respiration apparatus, namely, 3.79 c.c. It should be noted that these averages 

 neither represent an equal number of experiments nor comparison experiments 

 with the same subject in the two different forms of apparatus, and consequently 

 do not in any way vitiate the conclusion drawn from the earlier experiments 

 that the carbon-dioxide production with the same individual is essentially the 

 same whether he is in the bed calorimeter or lying on the respiration apparatus. 

 Of the moderately severe and light cases, Case M was studied both with the bed 

 calorimeter and the respiration apparatus, giving essentially the same results.
