SPARRING—is a ceremony practised with game cocks during the time they are in feeding (alias training) to fight in any MAIN or MATCH, for which they stand engaged. When COCKS are brought up from their _walks_, and placed in their pens, some are, of course, too full in flesh; others, as much deficient: in the judgment of equalizing these different degrees, (by reducing the weight of one, and increasing the substance of the other,) does the art of cock-feeding entirely depend. On every second or third day, during the time they are preparing for the match, each cock has a _sparring_ with an opponent of nearly equal weight with himself; and this _sham fight_ continues a longer or shorter time, according to the flesh, weight, and wind, of each cock so exercised, in proportion to the superflux of substance he is required to lose. For the occasion, and that they may not injure each other, they are equally shielded with mufflers upon the parts where their spurs have been sawed off; and that they may be the better inured to labour, and prepared for difficulty, the ceremony takes place upon a truss or two of straw loosely scattered, that, having no firm hold for their feet, they have less power to oppose each other. Cocks too full of flesh, and foggy, that require a great deal of _sweating_ to bring them down to their proper match weight, are sometimes permitted to continue the controversy till nearly exhausted. SPAVIN-BLOOD—is a preternatural distension of the vein which runs down the inside of a horse's hock, forming a soft and elastic (or puffy) enlargement, commonly occasioning _weakness_, if not _lameness_, of the joint. They are in general produced by sudden _twists_ or _strains_, in short turns with loads, either in riding or drawing; and not unfrequently by too rapid turning in narrow stalls. The cure is frequently attempted by strong spirituous saturnine repellents, or powerful restringents, with a compress and bandage firmly fixed upon the part: these methods, however, seldom afford more than temporary relief. The former mode of operating, by incision, and instrumental extirpation, is in present practice entirely laid aside; a repetition BLISTER, or slightly FIRING, being the only means relied on to ensure certain obliteration. SPAVIN-BONE.—The defect so called, is an enlargement on the outside of the hock, originating in a gristly or cartilaginous protrusion, which increases gradually to a callosity, and ultimately to a perfect ossification as hard as the bone itself. In its early state, but little limping or impediment to action is observed; but as it advances in progress, the lameness becomes proportionally perceptible. A bone-spavin is never known to submit to liquid applications, or solvents of any description; repeated BLISTERINGS, and substantial FIRING, seem the only means by which the enlargement and its painful irritability can be reduced.
