The Arab holds, and, according to old Moslem travellers, has long held in these regions the position of an Osmanli in Arabia; he is a ‘superior person.’ As the Omani chiefs, however, like the Sherifs of El Hejaz, did not disdain servile concubines, many of their issue are negroids: of these hybrids some are exceedingly fair, showing African pollution only by tufty and wiry hair, whilst others, ‘falling upon their mothers,’ as the native phrase is, have been refused inheritance at Maskat, and have narrowly escaped the slave-market. The grandsons of purest Arabs who have settled in Africa, though there has been no mixture of blood, already show important physical modifications worked by the ‘mixture of air,’ as the Portuguese phrase is. The skin is fair, but yellow-tinted by over-development of gall; whilst the nose is high, the lips are loose, everted, or otherwise ill-formed; and the beard, rarely of the amplest, shrinks, under the hot-house air, to four straggling tufts upon the rami of the jaws and the condyles of the chin. Whilst the extremities preserve the fineness of Arab blood, the body is weak and effeminate; and the degenerate aspect is accompanied by the no less degraded mind, morals, and manners of the coast-people. The nervous or nervoso-bilious temperament of the Sons of the Desert here runs into two extremes: many Arabs are bilious-lymphatic, like Banyans; a few, lapsing into the extreme of leanness, are fair specimens of the ‘Living Skeleton.’ This has been remarked even of Omanis born and bred upon the Island. Those who incline to the nervous diathesis have weakly drooping occiputs and narrow skull-bases, arguing a deficiency of physical force, and they exaggerate the flat-sided unconstructive Arab skull—here an Indian may almost always be recognized by the comparative roundness of his calvaria. And as the Zanzibar Arab is mostly of burgher race in his own land, the forehead rarely displays that high development of the perceptive organs which characterizes the Bedawin.
