[16] He is generally called Abu Zerbin, more rarely Abu Zarbayn, and Abu Zarbay. I have preferred the latter orthography upon the authority of the Shaykh Jami, most learned of the Somal. [17] In the same year (A.D. 1429-30) the Shaykh el Shazili, buried under a dome at Mocha, introduced coffee into Arabia. [18] The following is an extract from the Pharmaceutical Journal, vol. xii. No. v. Nov. 1. 1852. Notes upon the drugs observed at Aden Arabia, by James Vaughan, Esq., M.R.C.S.E., Assist. Surg., B.A., Civil and Port. Surg., Aden, Arabia. "Kat [Arabic], the name of a drug which is brought into Aden from the interior, and largely used, especially by the Arabs, as a pleasurable excitant. It is generally imported in small camel-loads, consisting of a number of parcels, each containing about forty slender twigs with the leaves attached, and carefully wrapped so as to prevent as much as possible exposure to the atmosphere. The leaves form the edible part, and these, when chewed, are said to produce great hilarity of spirits, and an agreeable state of wakefulness. Some estimate may be formed of the strong predilection which the Arabs have for this drug from the quantity used in Aden alone, which averages about 280 camel-loads annually. The market price is one and a quarter rupees per parcel, and the exclusive privilege of selling it is farmed by the government for 1500 rupees per year. Forskal found the plant growing on the mountains of Yemen, and has enumerated it as a new genus in the class Pentandria, under the name of Catha. He notices two species, and distinguishes them as _Catha edulis_ and _Catha spinosa_. According to his account it is cultivated on the same ground as coffee, and is planted from cuttings. Besides the effects above stated, the Arabs, he tells us, believe the land where it grows to be secure from the inroads of plague; and that a twig of the Kat carried in the bosom is a certain safeguard against infection. The learned botanist observes, with respect to these supposed virtues, 'Gustus foliorum tamen virtutem tantam indicare non videtur.' Like coffee, Kat, from its acknowledged stimulating effects, has been a fertile theme for the exercise of Mahomedan casuistry, and names of renown are ranged on both sides of the question, whether the use of Kat does or does not contravene the injunction of the Koran, Thou shalt not drink wine or anything intoxicating. The succeeding notes, borrowed chiefly from De Sacy's researches, may be deemed worthy of insertion here.
