SHARK—was the most capital horse of his time; bred by MR. PIGOTT, foaled in 1771, got by MARSK, dam by _Snap_, out of the dam of _Warwickshire Wag_. This horse was proved, next to CHILDERS and ECLIPSE, to have been possessed of more speed than any horse ever bred or produced in the kingdom. He beat all his cotemporaries at every distance, (_long_ or _short_,) clearly demonstrating his superiority, whether they run for _speed_, or run for _bottom_. His distinct winnings are too remote from the present time to enumerate individually, but they amounted in the aggregate to a GOLD CUP value 123 guineas, eleven hogsheads of claret, and the astonishing sum of 20,000 guineas, in plates, matches, sweepstakes, forfeits, and bets. When no horse in England could be found to start against him, he was taken to America as a STALLION, although it was publicly affirmed, 10,000 guineas were offered for him before his departure; admitting which to be the fact, it could have been done with no other motive than to render him a private STALLION for the mares of those _only_ who subscribed to the aggregate. SHOEING of HORSES,—which for time immemorial remained in its almost original state, has for the last fourteen years become an object of importance and general investigation. What for a century before was never thought worthy a moment's consideration, but by those whose professional province it was to FORM the SHOES, and _set them on_, is at length found worthy the fashionable and condescending inspection of NOBLEMEN, GENTLEMEN, the _polished_ groom, and the illiterate stable-boy. This change is well known to have originated in the publication of "TAPLIN'S Stable Directory" 1789; which, from its unprecedented popularity, passed through TWELVE editions in the short space of four years. To the appearance of this work, upon a subject so long neglected, are the public indebted for the much-wanted veterinarian improvement which has since taken place; as well as for the constantly increasing influx of veterinary writers, who, speculating upon the success of the original reformer, have obtruded upon the world such an infinity of _imitations_, and such a profusion of what they have thought _improvements_, that the discerning part of the public (plainly perceiving the deceptive imbecility of such attempts) rendered them abortive; a multiplicity of books having been announced upon veterinary subjects within the last seven years, which have been immediately buried in oblivion, without a sale sufficient to pay even for the paper upon which the works were printed.
