and utterly destroyed them, there being scarce any mention made from that time of either of these tribes.4 The former tribe of Jorham (whose ancestor some pretend was one of the eighty persons saved in the ark of Noah, according to a Mohammedan tradition5) was contemporary with Ad, and utterly perished.6 The tribe of Amalek were descended from Amalek the son of Eliphaz the son of Esau 7, though some of the oriental authors say Amalek was the son of Ham the son of Noah,8 and others the son of Azd the son of Sem.9 The posterity of this person rendered themselves very powerful,10 and before the time of Joseph conquered the lower Egypt under 5 D'Herbel.

The posterity of Ismael have no claim to be admitted as pure Arabs, their ancestor being by origin and language an Hebrew; but having made an alliance with the Jorhamites, by marrying a daughter of Modad, and accustomed himself to their manner of living and language, his descendants became blended with them into one nation. The uncertainty of the descents between Ismael and Adnân is the reason why they seldom trace their genealogies higher than the latter, whom they acknowledge as father of their tribes, the descents from him downwards being pretty certain and uncontroverted.1 The genealogy of these tribes being of great use to illustrate the Arabian
