The Biographical Dictionary of lbn Khallikán, although it hardly merits the extravagant praise bestowed upon it by Sir William Jones, has always, and deservedly so, been held in great estimation by all those who have been induced to enter upon the study of the noble language and extensive literature of the Arabs. There is, perhaps, no other book in the whole range of the learning of Islamism which throws so much light upon Arabic literature; while the extensive erudition, and general accuracy of the writer, have caused it to be considered of great authority upon all such subjects of information as come within the design of the work. It has consequently been very frequently referred to by Orientalists, and many detached lives have from time to time been given in different publications. Within the last four years two complete editions of the entire work have been undertaken by the zeal and industry of two distinguished Oriental scholars: the one by M. Wtistenfeld, lithographed, 4to. Göttingen, 1835–31), of which seven fasciculi, comprehending six hundred and ninety-eight lives, have been published; the other, in type, by the Baron Mac Guckin de Slane, 4to. Paris, 1838–40, of which three livraisons have appeared.
