The _Nubian_ (Homo Nuba) has caused ethnographers no fewer difficulties than the Dravida species. By this name we understand not merely the real Nubians (Schangallas, or Dongolese), but also their near kinsmen, the Fulas, or Fellatas. The real Nubians inhabit the countries of the Upper Nile (Dongola, Schangalla, Barabra, Cordofan); the Fulas, or Fellatas, on the other hand, have thence migrated far westward, and now inhabit a broad tract in the south of the western Sahara, hemmed in between the Soudanians in the north and the Nigritos in the south. The Nubian and Fula races are generally either classed with negroes or with the Hamitic races (thus with Mediterranese), but are so essentially different from both that they must be regarded as a distinct species. In former times they very probably occupied a large part of north-eastern Africa. The skin of the Nubian and Fula races is of a yellowish or reddish brown colour, more rarely dark brown or approaching to black. Their hair is not woolly but curled, frequently even quite smooth; its colour is dark brown or black. Their beard is much more strongly developed than in negroes. The oval formation of their faces approaches more to the Mediterranean than to the Negro type. Their forehead is high and broad, their nose prominent and not flat, their lips not so protruding as in the negro. The language of the Nubian races seems to possess no relationship to those of genuine negroes. The _Caucasian_, or _Mediterranean man_ (Homo Mediterraneus), has from time immemorial been placed at the head of all races of men, as the most highly developed and perfect. It is generally called the Caucasian race, but as among all the varieties of the species, the Caucasian branch is the least important, we prefer the much more suitable appellation proposed by Friedrich Müller, namely, that of Mediterranean, or Midland men. For the most important varieties of this species, which are moreover the most eminent actors in what is called “Universal History,” first rose to a flourishing condition on the shores of the Mediterranean. The former area of the distribution of this species is expressed by the name of “Indo-Atlantic” species, whereas at present it is spread over the whole earth, and is overcoming most of the other species in the struggle for existence. In bodily as well as in mental qualities, no other human species can equal the Mediterranean. This species alone (with the exception of the Mongolian) has had an actual history; it alone has attained to that degree of civilization which seems to raise man above the rest of nature.
