Nine different rations were fed, and the digestion trials were made in 

 triplicate, different quantities of the feeds being used in each of the three 

 trials. The first three rations contained but one feed each, the next 

 three contained two feeds each, and the last three contained three feeds 

 each. A feature of the rations was the variations presented as to quan- 

 tities and proportions, and in each of the last three rations the quantity 

 in one feed was varied, while the other two were kept constant. This 

 provided means for checking the influences exerted by the specific 

 components of the rations. The composition of the various rations and 

 the weight of the feces excreted daily are given in Table II. The per- 

 centage composition of the feces is given in Table III.
