SWEAT—is the transpiration of perspirative matter through the skin by the effect of an increased circulation of the blood. This, in a moderate degree, is so conducive to the _promotion_ of HEALTH, that those horses who regularly enjoy exercise to a proper state of perspiration, occasionally, and at proper times, are always in the highest condition; provided they are taken care of in proportion to the exercise each has had, or the work he has undergone. By the appearance of a horse in a high perspiration, immediate judgment may be formed of the property of his blood; and in a collateral degree, of the state of his health; for when a horse in good condition is under a profuse perspiration, the sweat is so congenially incorporated with the coat, (particularly if the horse is _well bred_,) that the hair lays so uniformly one way, that if the sun happens to shine, it seems a covering of satin: on the contrary, when a horse, after equal (or, in fact, much less) exertion, bears a _greasy_ kind of perspiration upon the surface, with the coat turning in different directions, bearing a gross matted appearance, and of a faint fœtid effluvia, the blood is in an improper state, and the horse in very bad condition. SWEATING a horse in the _stable_, by the administration of medicine, is a practice, the propriety of which has not hitherto been clearly ascertained; at least not perfectly demonstrated upon the true principles of science, uncontaminated by the obtrusive aid of deceptive speculation. See "TARTAR EMETIC." SWEATING FOR THE TURF—is a sporting ceremony with training-grooms, to which, in their opinion, no small probable consequence is attached; as is fully confirmed by the invariable punctuality with which it is performed. The two reasons assigned for the necessity of this operation, is to preserve the WIND in its proper state of _purity_, and to prevent a superfluous and improper _accumulation_ of FLESH. Horses in training are (in strict conformity with this intent) sweated at certain periods, or intervals, of six, seven or eight days each; which are brought nearer to, or delayed farther from each other, by the increasing or reduced state of the subject so to be sweated. The ceremony is performed in the morning, soon after the dawn of day, under the ancient superstitious opinion, that the AIR is then more _pure_ than at any other part of the twenty-four hours; and with those whose department it is to execute the office, as much _imaginary_ consequence appertains to it, as to making up the most important national dispatches at the principal office of Administration.
