[Section IV.]--M. Zotenberg proceeds to give an account of one or two very important MSS. of the Nights in the Bibliothèque Nationale. One of these is a MS. which belonged to the elder Caussin, and was carefully copied by Michael Sabbagh from a MS. of Baghdad. Prof. Fleischer, who examined it, states (Journal Asiatique, 1827, t. II., p. 221) that it follows the text of Habicht, but in a more developed form. M. Zotenberg copies a note at the end, finishing up with the word "Kabíkaj" thrice repeated. This, he explains, "est le nom du génie préposé au régne des insectes. Les scribes, parfois, l'invoquent pour preserver leurs manuscrits de l'atteinte de vers." This MS. was copied in Parts on European paper at the beginning of the century, though Caussin de Perceval was not acquainted with it in 1806, but only with a MS. of the Egyptian redaction. This MS. agrees with Galland's only as far as the 69th Night. It differs from it in two other points; it contains No. 1c, and the end of No. 3 coincides with the end of Night 69. The contents of Nights 70-1001 are as follows: 246, 4, 5, 6, 20, 7, 153, 21, 170, 247, The Unhappy Lover confined in the Madhouse (probably = 204c), 8, 191, 193,174, 9, 9b (not 9a, or 9aa) and as episodes, 155, 32, and the story of the two brothers 'Amír and Ghadir, and their children Djamil and Bathina. Another MS., used by Chavis and Cazotte, and Caussin de Perceval, was written in the year 1772. It has hitherto been overlooked, because it was erroneously stated in the late M. Reinaud's Catalogue to be a MS. containing part of the 1001 Nights, extending from Night 282 to Night 631, and copied by Chavis. It is not from Chavis' hand, and does not form part of the ordinary version of the Nights, but contains the following tales: 174, 248, Story of King Sapor, 246, 3a, 36, 3c, 153, Story of the Intendant, the Interpreter, and the Young Man; 247, 204c, 240, 250, Story of the Caliph and the Fisherman (probably = 156), the Cat and the Fox, and the Little Bird and the Fowler. Another MS., really written by Chavis, commences exactly where Vol. 3 of Galland's MS leaves off, i. e. in the middle of No. 21, and extends from Night 281 to Night 631. M. Zotenberg supposes it to have been written to supply the place of the last volume of Galland's set. It contains the following tales in addition to the conclusion of No. 21: 170, 247, 204c, 8, 191, 193 and 174. M. Zotenberg suggests that the first part of this MS may have been copied from Galland's last volume, which may have existed at the time in private hands. The two last MSS. contain nearly the same tales, though with numerous variations. M. Zotenberg discusses the hypothesis of Chavis' MS. being a translation from the French, and definitely rejects it.
