Colorado Fodders. 
39 
grams galactan, of which 286 grams or 83.96 per cent, were di¬ 
gested. The differences here are quite marked and, so far as the 
quantity digested is concerned, apparently in favor of the native 
hay. 
§102. If we, in like manner, compare the results obtained by 
determining the furfurol, we will observe that other differences 
are strongly indicated.

§103. We observe that the furfurol yielding substances in 
these two fodders must be very different. Those removed by alco¬ 
hol,. water and hydric chlorid from the alfalfa hay having a much 
higher coefficient of digestion than those dissolved out of the native 
hay, while the furfurol yielding bodies removed by the one per cent, 
sodic hydrate from the alfalfa show a low coefficient of digestion, 
much lower even than the corresponding substances in the native 
hay. When we come to the portion that I have designated cellulose, 
we find the amount of furfurol digested in the two cases and also 
the coefficients of digestion very close together, so that this factor 
would apparently fall out of our consideration. The same is in¬ 
dicated by the amount of cellulose digested in these two cases, the 
three sheep having digested 1,441 grams cellulose fed as alfalfa and 
1,502 grams fed as native hay. As pure cellulose yields from 2 to 
2.5 per cent, of furfurol, and we obtained for the alfalfa cellulose 
1.919 and for that from the native hay, 2.041 per cent, furfurol. 
the two products are probably almost pure cellulose, and the above 
results in regard to the cellulose are such as we should expect. 
§104. In the case of the native hay, we find that the coeffi¬ 
cients of digestion for the furfurol are low, except in the case of that 
yielded by the cellulose. The most marked features are the deport¬ 
ment of those compounds yielding furfurol, but which are soluble 
in one per cent, solutions of hydric chlorid or sodic hydrate. Such 
substances removed from alfalfa by one per cent, hydric chlorid 
seem to be wholly digestible, while those removed by the sodic 
hydrate are only slightly digestible. The alfalfa consumed con¬ 
tained substances soluble in the one per cent, hydric chlorid, which
