The nations of the whole northern part of Africa, from the Mediterranean to the Tropic, we have already mentioned. All those beyond the Tropic, from the Red Sea to the Ocean, an extent of 100 or 150 leagues, are of the Moorish species, though so tawny that they appear almost black. The women are rather fairer than the men, and tolerably handsome. Among these Moors there is a vast number of mulattoes, who are of a black still more deep, their mothers being negro women, whom the Moors purchase, and by whom they have a number of children. Beyond this territory, in the 17th or 18th degree of north latitude, we find the negroes of Senegal and Nubia, both on the coast of the western ocean and that of the Red Sea; and after them all the other nations of Africa, from the 18th degree north to the 18th degree south latitude, are perfectly black, the Ethiopians or Abyssinians excepted. The portion of the globe by Nature allotted to this race of men, therefore, contains an extent of ground, parallel to the equator, of about 900 leagues in breadth, and considerably more in length, especially northward of the equinoctial line. Beyond the 18th or 20th degree of south latitude the natives are no longer negroes, as will appear when we come to speak of the Caffres and Hottentots. By confounding the Ethiopians with their neighbours the Nubians, who are nevertheless of a different race, we have been long in an error with respect to their colour and features. Marmol says, the Ethiopians are absolutely black, that they have large faces and flat noses, and in this description the Dutch travellers agree. The truth, however, is, that they differ from the Nubians both in colour and features. The skin of the Ethiopians is brown or olive-coloured, like that of the southern Arabs, from whom probably they derive their origin. They are tall, have regular features, strongly marked; their eyes are large and beautiful; their noses well proportioned; their lips thin, and their teeth white. The Nubians, on the contrary, have flat noses, thick and prominent lips, and their faces exceedingly black. These Nubians, as well as the Barberins, their western neighbours, are a species of negroes not unlike those of Senegal.
