SITFAST.—A sitfast is an eschar upon the side of a horse, which having been originally a warble, from the pressure and friction of the girth-buckle, (indiscreetly permitted to come upon, or near to, the edge of the pad,) is, by a repetition of the injury, converted into a _sitfast_; or, in terms of easier comprehension, a circular or oblong space of the integument, so completely cauterized by the repeated heat and friction, that it bears all the appearance of a piece of burnt leather inserted upon the spot. When, by carelessness and neglect, it has acquired the state now described, there is but one mode of cure, which is instrumental extirpation. The edge being raised so as to admit of being taken hold of by either FORCEPS, or common PINCERS, it may be separated from the substance to which it adheres, by any common operator, and healed in a few days, almost as soon, and with as little difficulty, as the most trifling and superficial laceration. SKITTISH.—A horse is said to be SKITTISH, who is considerably above himself both in _spirit_ and _condition_; displaying much more of pleasure in exercise, and the enjoyment of air and conditional freedom, (from the narrow confines of a stable,) than the least tendency to habitual _vice_. A skittish horse will jump two or three feet at the flight of a sparrow, or dance a _saraband_ upon the rumbling approach of a carriage: he is (unless weary with work) always alive with _gaiety_ and _motion_, without the least intentional injury to those who ride or drive him. There are those who confound the terms, and consider a SKITTISH and a STARTING horse one and the same thing; but they are in the eye of accuracy by no means _synonymous_.
