In A the cranium is elongated, narrow, but otherwise mediately developed in front, with great breadth and fulness in the whole posterior region. The nasal bones, though prominent, are broad, short, and concave, and the upper jaw is everted. There is, also, a remarkable distance between the eyes. The facial angle measures 81°, the internal capacity 85 cubic inches. In the second head, B, the head is long and narrow, with a receding forehead, flat or concave nasal bones, and short, everted upper maxilla. Facial angle 78°; internal capacity 77 cubic inches. A glance at these two crania will satisfy any one that they possess, in degree, both the conformation and expression of the Negro. The third skull, that of a child of two years of age, corresponds in general form with the preceding, without having the African characteristics quite so obviously expressed. It therefore follows, from all the evidence we possess in relation to the Copts, that, as a people, they partake sensibly, and sometimes largely, of Negro lineage. An inspection of the royal portraits preserved in Rosellini, shows several heads which are obviously of the Coptic form; those, for example, of Sabakon and Tirhaka, of the Ethiopian dynasty, and of the queen Metumva, of an earlier epoch. (Plate XIV.) The same lineaments, though in less degree, are also obvious in the effigies of Sheshonk (Shishak) and Osorkon II., of the twenty-second dynasty, and in a few others of different periods of time. I wish it to be understood that I do not say these sovereigns were of Coptic lineage; but merely that their physiognomy, as expressed on the monuments, has the Coptic character. The history of the Copts remains an enigma in Egyptian ethnography. ------------------------------------------------------------------------ 7. THE NUBIANS.
