we follow pigeons on down to the days of 'that most skilful breeder Sir John Sebright,' who 'used to say, with respect to pigeons, that he would produce any given feather in three years, but it would take him six years to produce beak and head. (p. 31.) Now all this is very pleasant writing, especially for pigeon-fanciers; but what step do we really gain in it at all towards establishing the alleged fact that variations are but species in the act of formation, or in establishing Mr. Darwin's

Many cases are on record, showing that a race may be modified by occasional crosses, if aided by the careful selection of those individual mongrels which present any desired character; but that a race could be obtained nearly intermediate between two extremely different races or species, I can hardly believe.

. I will here add a somewhat different case, as it connects in a striking manner latent characters of two classes. Mr. Hewitt61 possessed an excellent Sebright gold-laced hen bantam, which, as she became old, grew diseased in her ovaria, and assumed male characters. In this breed the males resemble the females in all respects except in their combs, wattles, spurs, and instincts; hence it might have been expected that the diseased hen would have assumed only those masculine characters which are

never be answered by direct evidence, as he propagates his kind so slowly and cannot be subjected to experiment; but the almost universal practice of all races at all times of avoiding closely-related marriages is an argument of considerable weight; and whatever conclusion we arrive at in regard to the higher animals may be safely extended to man. Turning now to Birds: in the case of the Fowl a whole array of authorities could be given against too close interbreeding. Sir J. Sebright positively

Sir John Sebright, whose fame is perpetuated by the Sebright Bantam, used to spend two and three days in examining, consulting, and disputing with a friend which were the best of five or six birds. 17 Mr. Bult, whose pouter-pigeons won so many prizes and were exported to North America under the charge of a man sent on purpose, told me that he always deliberated for several days before he matched each pair.

To give one instance: the King of Wurtemberg, after twenty-five years' careful breeding, that is after six or seven generations, made a new breed of cattle from a cross between a Dutch and Swiss breed, combined with other breeds.24 The Sebright bantam, which breeds as true as any other kind of fowl, was formed about sixty years ago by a complicated cross.25 Dark Brahmas, which are believed by some fanciers to constitute a distinct species, were undoubtedly formed26 in the United States, within a
