NOTE 27.--_On the Title and Office of_ Khaleefeh. As most of our best authors on Oriental subjects have for some years past deviated from our old general mode of writing this title, substituting (for "Caliph") "Khalif," "Khalífah," &c., I have taken the same liberty. It cannot be correctly written, at the same time congenially with our language and with its orthography in Arabic characters, otherwise than "Khaleefeh" or "Khaleefah;" and of these two modes I adopt the one which agrees with the manner in which the title is most generally pronounced by the Arabs. The meaning of this title is "Successor," or "Vicar;" and it was originally given to the universal sovereigns of the Muslim Arabs, as signifying "Successor of the Prophet;" but afterwards, in a more exalted sense, as "Vicar of God:" the Khaleefeh being the head of the religion as well as the supreme political governor, or at least arrogating to himself the right to possess such supremacy, throughout the whole Muslim world. [The last of the Khaleefehs died in Egypt shortly after the Turkish conquest of that country, or in the year of the Flight, 950. After the overthrow of the house of El-'Abbás by Hulágù, certain of its members obtained an asylum at the court of the Memlook Sulṭáns, and continued the line of the Khaleefehs, with spiritual, but no temporal, authority until it ceased in the person of El-Mutawekkil, who delegated his office to the Sulṭán Seleem I.; it is consequently held by the Sulṭán of Turkey. The Emperors of Morocco, being descendants of the Prophet, also claim and receive from their subjects the title of Khaleefeh.[256]--ED.] NOTE 28. The stories in which this justly-celebrated man is mentioned will, I think, be more agreeable to those readers who are unacquainted with his history, of which, therefore, I shall say nothing. NOTE 29. Mesroor was a black eunuch, and a favourite servant of Er-Rasheed. The name signifies "happy." NOTE 30. "Ṭabareeyeh" is the modern name for Tiberias. NOTE 31.--_Description_ of Kháns, or Wekálehs. A Khán is a building chiefly designed for the accommodation of merchants, and for the reception of their goods. In Egypt, a building of this kind is generally called a Wekáleh. I have described it, in a former work, as surrounding a square or oblong court, and having, on the ground-floor, vaulted magazines for merchandise, which face the court, and are sometimes used as shops. Above these are generally lodgings, which are entered from a gallery extending along each of the four sides of the court; or, in the place of these lodgings, there are other magazines: and in many kháns or wekálehs which have apartments designed as lodgings, these apartments are used as magazines. In general, the building has only one common entrance; the door of which is closed at night, and kept by a porter.
