Sir John Sebright says, “a breed cannot be improved, or even continued in the degree of perfection at which it has already arrived, but by breeding from individuals, so selected as to correct each other’s defects, and by a judicious combination of their different properties (a position that I believe will not be denied); it follows that animals must degenerate by being long bred from the same family, without the intermixture of any other blood, or from being what is technically called _bred in-and-in_.” To Mr. Meynell’s opinion to the contrary, he replies—“Mr. Meynell’s fox-hounds are quoted as an instance of the success of this practice (i. e. _the in-and-in_); but, on speaking to that gentleman upon the subject, I found that he did not attach the meaning that I do to the term in-and-in. He said, that he frequently bred from the father and the daughter, and the mother and the son. This is not what I consider as breeding in-and-in; for the daughter is only half of the same blood as the father, and will probably partake, in a great degree, of the properties of the mother.” Again: “I have tried many experiments by breeding in-and-in upon dogs, fowls, and pigeons; the dogs became, from strong spaniels, weak and diminutive lap-dogs; the fowls became long in the legs, small in the body, and bad breeders.” Sir W. C——n, in his _Treatise on Greyhounds_, is unfavourable to breeding a kin. He says, “If continued for some litters, a manifest inferiority of size, and a deficiency of bone, will soon be visible, as well as a want of courage and bottom; though the beauty of the form, with the exception of the size, may not be diminished.”—_Blaine._—_Sir John Sebright._ BRENT GOOSE (_Anas Bernicla_, LINN.; _Le Cravant_, BUFF.), _s._ [Illustration] This is of nearly the same shape, but somewhat less than the Bean Goose, from which it differs in the colour of its plumage, being mostly of a uniform brown, the feathers edged with ash; the upper parts, breast and neck, are darker than the belly, which is more mixed and dappled with paler cinereous and gray: the head and upper half of the neck are black, excepting a white patch on each side of the latter, near the throat: the lower part of the back and rump are also black: the tail, quills, and legs dusky: the bill is dark, rather of a narrow shape, and only about an inch and a half long: the irides are light hazel. In the female and the younger birds, the plumage is not so distinctly marked, and the white spots on the sides of the neck are often mixed with dusky; but such varyings are discernible in many other birds, for it seldom happens that two are found exactly alike.
