The watery extract, when dry, has the flavor and taste of dry bread or rusk. This 
is the fact with all the sediments obtained by water from hay or the dried grasses. This 
flavor, with the slightly bitter principle of the extract, renders hay an agreeable and 
pleasant food to the ruminants. The amount of matter dissolved in cold water aided by 
macerating several days, and after pressing the insoluble fibre in a linen bag, furnishes 
from the maize foliage 40 to 60 per centum. All the soluble parts are taken up; and the 
fibre is left, after being dried, in the state in which it passes from the intestinal canal. This 
matter, which has been removed by water, is not entirely soluble : it appears, after standing, 
that the chlorophyl and wax are suspended in the menstruum, and by rest are slowly de¬ 
posited. So some of the resinous matter is obtained in the watery solution. The solution, 
when its temperature is raised to 140 - 180°, gives invariably flakes of a coagulum which 
is undoubtedly albumen. So a precipitate is given afterwards by acetic acid. 
These several products are more or less colored by, and still furnish the characteristics 
of, the elements to which they are referred. The chlorophyl does not appear to be as¬ 
similated, inasmuch as it appears in the excrements, and gives them in ruminants their 
green color. The wax, however, with which it is associated, disappears in part at least, 
and is undoubtedly, along with the resinous matters, comprised among the calorifient 
bodies. 
The albuminous matters (including casein) which are destined to supply the waste in 
the animal system, in the maize plant cut July 5, amount to 7*96; in that cut in July 
6, to 3*80; and in the leaves of (he ripe maize cut September 1, to 1*83 per centum. In
