An Arabic MS., in seven volumes, written in 1764-5, and containing what is rarely met with, a complete collection of the Thousand and One Tales of the _Arabian Nights' Entertainments_, was bought from Capt. Jonathan Scott for £50. Mr. Scott published, in 1811, an edition of the Tales, in six volumes, in which this MS. is described. He obtained it from Dr. White, the Professor of Hebrew and Arabic at Oxford, who had bought it at the sale of the library of Edward Wortley Montague, by whom it had been brought from the East. It is noticed in Ouseley's _Oriental Collections_, vol. ii. p. 25. A.D. 1805. In this year the last volume (numbered 142) of Dr. Holmes' Collations of MSS. of the Septuagint-Version, was deposited in the Library. This great and important work had been commenced in the year 1789; it was intended to embrace collations of all the known MSS. of the Greek text, as well as of Oriental versions; and for seventeen years, by the help of liberal subscriptions, in spite of the difficulties interposed by the continental wars, the collection of the various readings from MSS. in libraries throughout Europe was carried on. And each year's work was, on its completion, deposited in the Bodleian. During this period, annual accounts were published of the progress of the work, which possess both critical and bibliographical interest; and the results of the whole are seen in the fine edition printed at the Clarendon Press, in five vols., folio, 1808-1827. The MSS. of the distinguished classical scholar, James Philip D'Orville, who died at Amsterdam, Sept. 14, 1751, were bought for £1025. After the purchase was completed, a question arose whether the University of Leyden were not, by the terms of his will, entitled to them after the death of his son, but it was ascertained that this provision was only made in case his son did not reach manhood. The collection numbers about 570 volumes, containing many valuable Greek and Latin Classics, together with numerous collations of texts, and annotated printed copies. Thirty-four volumes contain correspondence (autograph and in copy) of Is. Vossius, Heinsius, Cuper, Paolo Sarpi, Beverland, and the letters addressed to D'Orville by all the great scholars of his time. And thirty-eight volumes, in folio and quarto, contain _Adversaria_ of Scipio and Alberic Gentilis. There are also six Turkish and Arabic MSS. The gem of the collection is a quarto MS. of _Euclid_, containing 387 leaves, which was written, 'χειρι Στεφανου κληρικου,' A.M. 6397 = A.D. 889. It contains a memorandum by one Arethas of Patras, that he bought the book for four (or, most probably, fourteen,) _nummi_. A Catalogue of the MSS., compiled anonymously by Dr. (then Mr.) Gaisford, was printed in quarto, in 1806. D'Orville's signature occurs in the Admission-book as having been admitted to read on Aug. 18, 1718.
