The Negro transported into the same countries has also undergone remarkable changes. His colour has paled, his features have improved, and his physiognomy is altered. “In the space of 150 years,” says M. Elisée Reclus, “they have passed a good fourth of the distance which separates them from the whites, as far as external appearance goes.” Lyell’s opinion is almost the same. Moreover, when visiting two Negro churches, at Savannah, he remarked that the odour so characteristic of the race was scarcely appreciable. A long medical experience at New Orleans has shown Dr. Visinié that the blood of the Negro Creole has lost the excess of plasticity which it possessed in Africa. With MM. Reiset, de Lisboa, etc., with even Nott and Gliddon, let us add that, while the physical type has undergone modification, the intelligence has improved, and we shall have to recognise that in the United States a _sub-Negro race_ has been formed, derived from the imported race. XII. Thus the European White and the African Negro, when under the influence of new conditions of life, have both undergone modification. Moreover both, according to M. Reclus, whose statements are confirmed by those of M. l’Abbé Brasseur de Bonbourg, approximate to the indigenous races. Both of these authors seem to admit that at the end of a given time, whatever be their origin, all the descendants of Whites or of Negroes who have immigrated to America will become Red-skins. When two such intelligent observers arrive at an identical and certainly quite unexpected conclusion on such a question, the facts must be very patent. Yet they have forced their meaning, from not having taken sufficient account of the nature of the problem. That the Negro and the White should replace some of their features and characters by some of the features and characters belonging to the indigenous races, is quite natural. When subject to the action of the conditions of life which have formed the local races, they could not help being influenced by it to a certain extent. But they will never on that account be confused with the local races nor with each other, any more than the White transported to Africa would ever become a true Negro, or the European descendants of a Negro would ever become true Whites.
