In each experiment the digestibility of the ration was deter- 
mined in the usual manner, and also the carbon of food, feces, urine, 
and respiration (including methane, etc.), and the nitrogen and 
heats of combustion of food, feces, and urine. 
The experiments 
were made with every precaution and extended over a sufficient 
length of time to ensure normal results. 
respiratory products were determined in four or five separate periods 
of twenty-four hours each. No such complete experiments with
