As to the difference of colour between the Eboan Africans and the modern Jews, I shall not presume to account for it. It is a subject which has engaged the pens of men of both genius and learning, and is far above my strength. The most able and Reverend Mr. T. Clarkson, however, in his much admired Essay on the Slavery and Commerce of the Human Species, has ascertained the cause, in a manner that at once solves every objection on that account, and, on my mind at least, has produced the fullest conviction. I shall therefore refer to that performance for the theory[H], contenting myself with extracting a fact as related by Dr. Mitchel[I]. "The Spaniards, who have inhabited America, under the torrid zone, for any time, are become as dark coloured as our native Indians of Virginia; of which I myself have been a witness." There is also another instance[J] of a Portuguese settlement at Mitomba, a river in Sierra Leona; where the inhabitants are bred from a mixture of the first Portuguese discoverers with the natives, and are now become in their complexion, and in the woolly quality of their hair, perfect negroes, retaining however a smattering of the Portuguese language.
