noids and non-albiiminoids. As we Iiavo seen, recent in- 

 vestigations liave revealed tlie pre&ence of large amounts 

 of '' non-protein " in coarse fodder, especially in the earlier 

 stages of its growth. This non-protein is, in all proba 

 bility, entirely digestible, and it is easily to be seen that 

 its presence might affect the correctness of the abo\e re- 

 sults. 



The only experiments tonching this point are a few by 

 "Wolff * on sheep and on a horse, with hay cut from the 

 same field in two different years. These gave the fol- 

 lowing digestion coefficients, a for total nitrogenous matter, 

 i for trae protein :

These figures are somewhat conflicting as regards the 

 digestibility of the true protein in fodder cut at different 

 times, and it must be left for future investigations to de- 

 cide how far the results which have been obtained for the 

 total nitrogenous matter of coarse fodders are true of 

 their actual protein.
