The third family, an ancient and a noble race dating from A.C. 1900, and typified in history by Ishmael, still occupies the so-called Sinaitic Peninsula. These Arabs, however, do not, and never did, extend beyond the limits of the mountains, where, still dwelling in the presence of their brethren, they retain all the wild customs and the untamable spirit of their forefathers. They are distinguished from the pure stock by an admixture of Egyptian blood,[FN#5] [p.79] and by preserving the ancient characteristics of the Nilotic family. The Ishmaelities are sub-Caucasian, and are denoted in history as the Arab al-Mustarribah, the insititious or half-caste Arab. Oriental ethnography, which, like most Eastern sciences, luxuriates in nomenclative distinction, recognises a fourth race under the name of Arab al-Mustajamah. These “barbarized Arabs” are now represented by such a population as that of Meccah. That Aus and Khazraj, the Himyaritic tribes which emigrated to Al-Hijaz, mixed with the Amalikah, the Jurham, and the Katirah, also races from Al-Yaman, and with the Hebrews, a northern branch of the Semitic family, we have ample historical evidence. And they who know how immutable is race in the Desert, will scarcely doubt that the Badawi of Al-Hijaz preserves in purity the blood transmitted to him by his ancestors.[FN#6] [p.80] I will not apologise for entering into details concerning the personale of the Badawin[FN#7]; a precise physical portrait of race, it has justly been remarked, is the sole deficiency in the pages of Bruce and of Burckhardt. The temperament of the Hijazi is not unfrequently the pure nervous, as the height of the forehead and the fine texture of the hair prove. Sometimes the bilious, and rarely the sanguine, elements predominate; the lymphatic I never saw. He has large nervous centres, and well-formed spine and brain, a conformation favourable to longevity. Bartema well describes his colour as a “dark leonine”; it varies from the deepest Spanish to a chocolate hue, and its varieties are attributed by the people to blood. The skin is hard, dry, and soon wrinkled by exposure. The xanthous complexion is rare, though not unknown in cities, but the leucous does not exist. The crinal hair is frequently lightened by bleaching, and the pilar is browner than the crinal. The voice is strong and clear, but rather barytone than bass: in anger it becomes a shrill chattering like the cry of a wild animal. The look of a chief is dignified and grave even to pensiveness; the “respectable man’s” is self-sufficient and fierce; the lower orders look ferocious, stupid, and inquisitive. Yet there is not much difference in this point between men of the same tribe, who have similar pursuits which engender [p.81] similar passions. Expression is the grand diversifier of appearance among civilised people: in the Desert it knows few varieties.
