The advantages of a mixed diet are here well illustrated. 

 That the digestive power is in part an individual characteristic 

 is also well shown, since the subject S. in every period digested 

 the largest proportion of the protein, and in every case but one 

 D. digested the least. The protein of the corn was less digesti- 

 ble than that of the milk, and when the results are calculated 

 to the corn alone, only 61.2 per cent of the protein was found to 

 be digested.

These results are summarized in the above table in which the 

 coefficients are compared with those obtained at another time 

 with white flour bread. The following points may be regarded 

 as established : 



1. The digestibility of the protein and the availability of the 

 energy of the hulled corn are very low when the corn is com- 

 pared with white bread. 



2. The mixed diet was much more completely utilized by the 

 body than the simple diet.
