But in discussing this point, I shall beg leave, when speaking of these Horses, to change the word HIGH-BRED, and in its room substitute the word foreigner, or of foreign extraction. For perhaps it may appear, that the excellence we find in these Horses depends totally on the mechanism of their parts, and not in their blood; and that all the particular distinctions and fashions thereof, depend also on the whim and caprice of mankind. If we take a Horse bred for the cart, and such a one as we call a hunter, and a horse of foreign extraction, and set them together, the meanest judge will easily point out the best racer, from the texture, elegance, and symmetry of their parts, without making any appeal to blood. Allow but a difference in the texture, elegance, and symmetry of parts in different Horses, whose extraction is foreign, this principle will be clearly proved, and the word HIGH-BRED is of no use, but to puzzle and lead us astray: and every man's daily observation would teach him, if he was not lost in this imaginary error, particular blood, that, generally speaking, such Horses who have the finest texture, elegance of shape, and the most proportion, are the best racers, let their blood be of what kind it will, always supposing it to be totally foreign. If I was asked what beauty was, I should say proportion: if I was asked what strength was, I should say proportion also: but I would not be understood to mean, that this strength and beauty alone will constitute a racer, for we shall find a proper length also will be wanted for the sake of velocity; and that moreover the very constituent parts of foreign Horses differ as much from all others, as their performances. But this, however, will be found a truth; that in all Horses of every kind, whether designed to draw or ride, this principle of proportion will determine the principle of goodness; at least to that part of it which we call bottom. On the other hand, our daily observation will shew us, that no weak, loose, disproportioned Horse, let his blood be what it will, ever yet was a prime racer. If it be objected, that many a plain ugly Horse has been a good racer; I answer that all goodness is comparative; and that such Horses who have been winners of plates about the country, may be improperly called good racers, when compared to some others: but I can even allow a very plain Horse to be a prime racer, without giving up the least part of this system: for instance if we suppose a Horse (with a large head and long ears, like the Godolphin Arabian) a low mean forehand, slat sided, and goose rumped, this, I guess, will be allowed a plain ugly Horse; but yet if such a Horse be strong, and justly made in those parts which are immediately conducive to action; if his shoulders incline well backwards, his legs and joints in proportion, his carcase strong and deep, his thighs well let down, we shall find he may be a very good racer, even when tried by the
