EXPERIMENTAL METHODS. 



The methods followed in all of the experiments here reported are 

 practically identical with those described in detail in the previous 

 publication" already referred to, and need only be briefly outlined. 



The bread from the different sorts of flour was eaten with milk; the 

 amount of either was not limited, but the quantities eaten at each meal 

 were recorded. The separations of the feces were made by means of 



«U. S. Dept. Agr., Office of Experiment Stations Bui. 101.
