Note 10 — APPENDIX. No. I.

All the Bedouins of Soudan, of whom I have seen many individuals, differ entirely in colour and features from the aborigines, approaching more to the Arab cast: the aborigines are of the deepest black; but they are divided into two distinct races; the free Mohammedan blacks, who, though evidently of Negroe origin, have features not entirely Negroe; and the Negroe slaves, from the idolatrous countries, who have never mixed with Arabs, and therefore retain the true African features. The former by continually intermarrying with the Bedouin Arabs, their conquerors, have now become intimately intermixed with them; but no man of Bedouin extraction in any part of Africa ever marries a girl whose parents were not free people.
