Summary of Cocfficiaits (^Pcr Cent.). 

 Period VIII. 



The gluten feed appears to have been thoroughly digested, 

 showing higher coeiHcients than the average of previous trials. 

 It is probable that the addition of the gluten to the hay 

 ration somewhat increased the digestibility of the latter. It 

 not being possible, however, to ascertain to what extent 

 this increase took place, one is compelled to deduct from the 

 total ration the hay digested (using the coefficients obtained for 

 the hay when fed by itself), thus causing most of the gluten 

 coefficients to appear too high ^ (note especially the fiber). 



Green Diamond Sugar Feed. — This sugar feed has a 

 similar appearance and is of the same general type as those 

 already reported (see this report, pages 119, 120). Period 

 X. started with two sheep, but the faeces produced by one 

 sheep were so soft that it was not possible to complete the 

 test. Another trial with another sheep was also unsatisfac- 

 tory. A third trial, in Period XIV., with Paige Sheep IV., 

 was satisfactorily completed. 



Summary of Coefficients (Per Cent.). 



Periods X. and XIV. 



1 The addition of a concentrated feed rich in protein tends to improve the digesti- 

 bility of the total ration, especially the fiber. (See Kelln'er, loco citato, pages 51-53.)
