Hot Stables have been condemned by every veterinarian who has had occasion to mention them. They have been blamed for producing debility, inflamed lungs, diseased eyes, chronic cough, and recent cough, distemper, and some other evils, direct or indirect; and a cold stable has been recommended, times out of number, for preventing them. I have elsewhere stated, that a hot stable and a foul stable have always been confounded one with another, as if they were not different. Mr. Youatt is the only exception that I know of. He seems to regard a heated and an impure atmosphere as two. IJis distinction is not, indeed, very broadly marked, yet it can be traced. It is not wonderful that it should have been overlooked by others. Heat and impurity, almost uniformly arising from the same source, must as uniformly co-exist and operate in combination. Hence the common error of con sidering them as inseparable, or as a single agent. It must be obvious, however, that a heated atmosphere is capable of producing one series of effects, and an impure atmosphere another. The evils arising from impurity are described in connexion with the ventilation of stables. This is the proper place to consider the effects of heat. There is some difficulty in ascertaining precisely what they are.

Some experiments would almost be necessary to arrive at accurate conclusions. We have ample opportunity of examining hot stables, and of observing the health and condition of their occupants. But these hot stables rarely have a pure atmosphere. The air, as I have elsewhere observed, is never perfectly pure in any oc cupied stable; but by pure I here mean comparatively pure quite wholesome, yet not quite free from extraneous matters An atmosphere of untainted purity can not be obtained in the neighborhood of breathing animals, and it appears quite cer tain that it may suffer deterioration to a certain extent, without producing any evil. The only mode -of learning the effects of a hot atmosphere, would be to place a number of horses in an apartment heated by fire or steam, and so well ventilated that emanations from the lungs, the skin, and the evacuations, would escape before they had time to operate in combination with the heat. The keen advocates for hot stables might try the experiment for a few weeks or months, and such an experiment would tell us at once what heat will, and what it will not do.

So far as I have been able to observe, by close attention to a great number of horses confined in all kind of stables, it would appear that.

The Effects of Hot Stabling are only three in number. The first is a fine, short, glossy coat; the second, a strong disposition to accumulate flesh; and the third is an extreme susceptibility to the influence of cold. These are the permanent effects. Those produced by sudden removal from a cold to a warm stable are somewhat different. For the first week the horse looks as if he were a little fevered. He does not feed well, but drinks much. Sometimes he is dull, and sometimes restless, fidgety. If somewhat lusty, or if he eat and drink tolerably well, he often sweats in the stable, particularly about the flanks, the groin and quarters. In a few days he seems to become accustomed to the high temperature. His coat lies smoothly; it glitters as if it were anointed; the horse recovers his appetite, and rapidly takes on flesh.

The short glossy coat is not in this country any evil. The accumulation of flesh is not always desirable, but the stables are never cooled for the purpose of preventing it. The third effect, that is, the intolerance of exposure to cold, produced by hot stabling, is a serious evil. If all the diseases, mostly of a dangerous character, which are ascribed to sudden exposure in a cold atmosphere, really have such an origin, a hot stable can hardly be more destructive than a foul one. It is universally acknowledged, that sudden exposure to cold, that is, rapid abstraction of heat, is dangerous, but whether it have all the power which some attribute to it may be doubted. That cold often does mischief can not be denied, and that the hot stabled horse is in greatest danger is, I think, as unquestionable. The least exposure makes him shiver, and everybody knows that this shivering is very often followed by a deadly inflammation.

I do not say that hot stables will produce no other effect. speak only from my own observation, and of a stable without apparent impurity. When the air is tolerably pure, the heat can not rise to a great height, unless it be produced by artificial means. 1 have never seen a stable heated by fire, and can not say what would be the result of excessive heat. Diseased liver, debility, a broken constitution, are said to be the consequences of a long residence in a hot climate, but whether a horse's work and temperance save him from these, or whether an elevated temperature alone will produce them in him, I do not know. There is little analogy between a horse living in a hot stable, and a European living in a hot climate. Other circumstances differ so much that nothing could be learned by contrasting them.
