It has been said, that the sons of the Godolphin Arabian had better wind than other Horses, and that this perfection of the wind was in the blood. But when we consider any Horse thus mechanically made, whose leavers acquire more purchase, and whose powers are stronger than his adversaries, such a Horse will be enabled by this superiority of mechanism, to act with greater facility, and therefore it is no wonder that the organs of respiration (if not confined or straitened more than his adversaries) should be less fatigued. Suppose now, we take ten mares of the same, or different blood, all which is held equally good, when the Mares are covered, and have been esteemed so long before, and put to this Godolphin Arabian, let us suppose some of the colts to be good racers, and others very inferior to them; shall we condemn the blood of these mares which produced the inferior Horses? If so, we shall never know what good blood is, or where it is to be found, or ever act with any certainty in the propagation of this species, and it is this ridiculous opinion alone of blood, that deceives mankind so much in the breed of racers. If we ask the jockey the cause of this difference in the performance of these brothers, he (willing to account some how for it) readily answers, that the blood did not nick; but will a wise and reasoning man, who seriously endeavours to account for this difference, be content with such a vague, unmeaning answer, when, by applying his attention to matters of fact, and his observation to the different mechanism of these brothers, the difference of their performance is not only rationally, but demonstratively accounted for? But if this excellence of the racer should really be in the blood, or what is called the proper nicking of it, I must say, it is a matter of great wonder to me, that the blood of the Godolphin Arabian, who was a confined Stallion, and had but few Mares, should nick so well as to produce so many excellent racers; and that the blood of his son Cade, who has had such a number of Mares, and those, perhaps, the very best in the kingdom, should not nick any better than it seems to have done; for I do not conceive the performances of the sons of Cade to have been equal in any respect to the sons of the Godolphin Arabian; though I do not pretend to determine this myself, but shall leave it to the opinion of mankind.
