THE INCOME AND OUTGO OF NITROGEN IN THESE 

 EXPERIMENTS. 



As previously stated, the urine was collected for each experi- 

 ment beginning with the morning of the first day and ending 

 with the evening of the third day. The amount passed on ris- 

 ing (about 7 A. M.) in the m.orning of the first day was not 

 kept and that of the morning of the third day was included with 

 the amount collected. 



The weights of the urine, the percentage of nitrogen, weight 

 of nitrogen, heats of combustion per gram, and total heats of 

 combustion are given below. The balance of the income and
