It is to be regretted that the exact date of this species of Mangnall's Questions and Answers cannot be ascertained, for this would enable us to appreciate better the amount of knowledge displayed on the various subjects under discussion. Anyhow, it is certain that it must have been written some time after the doctrines of the Imam Shafai (he died A.D. 820) had been well-defined and established. Owing to certain medical and surgical queries and replies, it is to be presumed that the whole must have been worked up after the Arab school of medicine and physiology had arrived at their highest stage of perfection. The whole story is a good specimen of the state of civilization reached by the Arabs, and as such is worth a reference. Three other stories in the 'Nights' bear some affinity to the above, but they are much more limited, both as regards the subject they deal with and the information they supply. One is 'King Jali'ad and his vizier Shimas,' in Payne's eighth and Burton's ninth volume; another, 'History of Al-Hajjaj bin Yusuf and the young Sayyid,' in Burton's fifth supplemental; and the third, 'The Duenna and the King's Son,' in his sixth supplemental. The Rogueries of Dalilah the Crafty, and her daughter, Zeynab the Trickstress.--The tricks played by Dalilah the Crafty on all sorts of people in this story are of a nature that would make the tale amusing to the Arabs generally, and to the frequenters of coffee-houses particularly. Dalilah's father and husband had held lucrative appointments under the Khalifs of Baghdad, and, with a view to obtain something for herself and her daughter Zeynab, these two women determined to bring themselves to notice by playing tricks, and doing things which were likely to be talked of in the great city. In Europe at the present time the same method is often followed. Attempted assassinations, attempted suicides, complaints in the police-courts and cases in the law-courts are sometimes meant simply as an advertisement.[7] Anyhow, Dalilah's tricks played on various people are certainly amusing, and as they run ingeniously one into the other, it is somewhat difficult to describe them in a few words. The tale, to be appreciated, must be read through. Sufficient to add that Dalilah and Zeynab both eventually obtain what they wish, and the various things taken from the different parties are duly returned to them.
