»The heat of combustion of the urine was determined in the composite sample for each day and 
in the total composite for four days. The heat of combustion of the urine for the experiment as 
determined in this latter sample amounted to 0.139 calorie per gram, or a total of 535 calories for the 
urine of the whole experiment.
