SMITHFIELD—is the name of a most celebrated spot in the Metropolis, from which a SPORTSMAN is not likely to derive either _pleasure_ or _emolument_; unless it is in the purchase of diseased or emaciated subjects for his HOUNDS. To those in remote parts of the kingdom, it may not be inapplicable to be informed, that Smithfield is the great CATTLE MARKET for the consumption of the infinite body of inhabitants in the cities of London, Westminster, their suburbs, and the environs for some miles round. The principal days are MONDAY and FRIDAY in every week; on which some hundreds of OXEN, in a state of perfection for slaughter, and thousands of SHEEP and LAMBS, are constantly transferred to supply the immense demand. The afternoons of those days are principally appropriated to the purchase and sale of _aged_, _crippled_, and _worn-out_ horses; the greater part of whom are only fit to receive sentence from the INSPECTOR, previous to their being delivered to the _nacker_, (or slaughterman,) unless it is _some few_, with still remaining strength enough to drag the carts of the industrious about the inferior streets, with a supply of vegetables in the summer, and potatoes in the winter, for the accommodation of the lower classes of society. SNAFFLE.—The simplest and plainest BRIDLE-BIT is so called: it consists of only a single mouthpiece, having a joint in the middle, with a cheek of different lengths at each extremity, and an eye annexed to receive the reins; when which are added, it is then called a SNAFFLE (or single-reined) BRIDLE. When snaffle-bits are made very large in the mouth for breaking colts or fillies, they are then called MOUTHING-BITS. SNAP,—the name of a horse, as a STALLION, formerly held in high estimation: he was bred by the late EARL of SANDWICH; foaled in 1750; got by _Snip_; dam by _Fox_, grand-dam by _Bay Bolton_; from which the blood of both sire and dam may be traced to most of the Barbs and Turks ever brought to this country. There were also three others of this name, distinguished by different appellations; as Lord Chedworth's _Snap_; Wildman's _Snap_; and Latham's _Snap_. The first was got by _Old_ _Snap_; his dam by _Dormouse_, grand-dam by _Mixbury_. The second by _Old Snap_; dam by _Regulus_, grand-dam by Bartlet's _Childers_; going on both sides directly into Arabian blood. The third by _Snap_, dam by _Cade_, grand-dam by _Old Partner_.
