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 the ripe maize cut September 1, to 1-83 per centum. In
