METABOLISM IN FEVER AND CERTAIN INFECTIONS 125 



in metabolism found in this disease should be ascribed to the exudate. 

 We must certainly be careful in transferring results obtained in pneu- 

 monia to other fevers. No other infectious disease shows such a diminu- 

 tion in chlorid excretion or such a marked epicritical rise in nitrogen 

 output.

 spiratory metabolism in pneumonia as in other diseases. Investigators

 The line of dashes shows the nitrogen excretion including the nitrogen of the feces 

 which averaged 3 grams a day. Note that the urinary nitrogen rose to 40.8 gm. 

 the day after the crisis. At the same time there was a rapid fall in body weight 

 although the patient was receiving in his food almost enough calories to cover his 

 requirement. 



find these patients poor subjects on account of the dyspnea and coughing 

 which interfere with any mouth-breathing or mask experiments. In 

 respiration chambers it is almost impossible to keep the patients quiet 

 for the long experimental periods. There are no published results giving 

 the figures for delirious patients whose heat production must be two or 

 three times as high as that of patients resting quietly in bed.
