consumed was 10,585 grams, and the feces voided 5,193 grams, 
which gives us a coefficient of 23.47 for the digestibility of this 
group in the hay. 
§90. The results obtained in feeding this hay were fairly 
good, the net result being a gain of three and one-half pounds dur¬ 
ing the five days between the weighings. The dry matter voided 
in the feces was almost one-half of that consumed, and the coeffi¬ 
cients of digestion were found to be comparatively low. This hay,- 
designated as native hay, commands a high price and is held in high 
esteem, particularly for horses. 
§91. In this experiment no grain or other fodder than the 
hay was fed. I wished to study the hay and not to determine an 
advantageous ration, of which it should be a part. 
§92. If we compare the data furnished by the results obtained 
with alfalfa and those obtained in the case of the native hay, we 
observe very great differences. In the first place, the alfalfa is evi¬ 
dently a more palatable food to sheep than this hay or timothy. 
There was fed of the native hay, 13,182 grams, the sheep left 2,596 
grams; of the alfalfa, 13,350 grams, of which 987 grams were 
left; of the timothy, 13,320 grams, of which 4,493 grams were left. 
These hays were all cut in order to induce the sheep to eat it up 
clean as possible. Sheep prefer, for instance, the leaves of alfalfa 
to the stems, and I wished to force them to eat the stems as well as 
the leaves.

§93. In regard to the relative amounts of the extracted matter 
digested and corresponding coefficients, we observe that much larger ‘ 
amounts of those substances dissolved out by the eighty per cent. ' 
alcohol, cold and hot water, the latter with addition of malt ex- - 
extract, were digested in the case of the alfalfa than in that of the , 
native hay, and the coefficients of digestion are materially higher. 
The reverse is the case with those substances dissolved out by the i
