The argument mainly relied on by those who believe in the multiple origin of our domestic animals is, that we find in the most ancient records, more especially on the monuments of Egypt, much diversity in the breeds; and that some of the breeds closely resemble, perhaps are identical with, those still existing.
Blyth, whose opinion, from his large and varied stores of knowledge, I should value more than that of almost any one, thinks that all the breeds of poultry have proceeded from the common wild Indian fowl(Gallus bankiva).
They believe that every race which breeds true, let the distinctive characters be ever so slight, has had its wild prototype.
The manner of flight differs remarkably; as does in some breeds the voice and disposition.
Moreover, I do not believe that any ornithologist would place the English carrier, the short-faced tumbler, the runt, the barb, pouter, and fantail in the same genus; more especially as in each of these breeds several truly-inherited sub-breeds, or species as he might have called them, could be shown him.
Great as the differences are between the breeds of pigeons, I am fully convinced that the common opinion of naturalists is correct, namely, that all have descended from the rock-pigeon (Columba livia), including under this term several geographical races or sub-species, which differ from each other in the most trifling respects.
That the productions of such marriages are generally scrofulous, rickety, or deformed children; by which means the family seldom continues above three generations, unless the wife takes care to provide a healthy father, among her neighbours or domestics, in order to improve and continue the breed
Jerry, who heard, registered, and recognized many words that were as truly tools of thought to him as they were to humans, but who, by inarticulateness of birth and breed

On two occasions I met with in this province some oxen of a very curious breed, called nata or niata.
The breed is universally believed to have originated amongst the Indians southward of the Plata; and that it was with them the commonest kind.
