horse cen endure the depressing influences of a cold atmosphcre, 
because he has within the body a vast generator and non-conductor 
of heat in the form of adipose matter. It has been proved that 
the immediate cause of death in warm-blooded animals, when food 
has been withheld, was their inability to keep up that temperature 
necessary for the integrity of vital operations. The animal located 
in an air-tight stable is, probably, surrounded by an atmosphere 
almost equal in temperature to that of his own body, and, conse- 
quently, he does not require so much food as the former. Hence, 
the amount of food necessary in the one case might be too much for 
another, and, consequently, operate injuriously. A cold, bracing 
wind is said to “sharpen the appetite.” The inhabitants of north- 
ern regions require more food than those of the southern. A horse, 
therefore, of weak muscular organization, the subject of debility, 
requires « comfortable stable, and food that will develop muscles 
Now, it has been ascertained that horse-beans contain more of the 
nitro-albuminous principles than any other article of diet. Eng- 
lish horses are very partial to the same, and in such the develop- 
ment of muscle is very remarkable; consequently, a fat horse 
requires less of the nitro-albuminous principle, and more of the 
aqueous, in the form of carrots, potatoes, and beets. 
It must never be forgotten that some horses will keep in fair 
working order on a moderate supply of alimeni. In such cases, 
we infer that the digestive organs are in a state of activity capable 
of extracting all the nutrient properties from the same. On the 
other hand, a horse performs less work than the former, consumes 
twice as much food, yet actually loses flesh. The digestive organs 
are then at fault. A horse, however, may lose flesh, become weak 
in the legs, ete., in consequence of the laborious nature of his em- 
ployment. Therefore, any derangement occasioned in this way 
prevents the food from being converted into healthy chyme, chyle, 
ot blood, and thus the necessary deposit of new matter is pre- 
vented. 
Most voraciou: feeders are dyspeptic, and such are almost never 
free frum intestinal worms. Their breath becomes feted; saliva, 
thick and tenacious ; excrement, slimy; and should the subject be 
fed on outs, the same would be found, after traversing the aliment- 
ary canal, unmasticated. The principal remedy for indigestion is 
shange in diet. Sometimes it may be proper to allow scalded <ats, 
although cooking does not add to their nutritive quality, yet, more
