Time glided away smoothly until the fever invaded our camp. Florian became seriously ill. My wife was prostrated by a severe attack of gastric fever, which for nine days rendered her recovery almost hopeless. Then came the plague of boils, and soon after a species of intolerable itch, called the coorash. I adopted for this latter a specific I had found successful with the mange in dogs, namely, gunpowder, with one fourth sulphur added, made into a soft paste with water, and then formed into an ointment with fat. It worked like a charm with the coorash. Faith is the drug that is supposed to cure the Arab; whatever his complaint may be, he applies to his Faky or priest. This minister is not troubled with a confusion of book-learning, neither are the shelves of his library bending beneath weighty treatises upon the various maladies of human nature; but he possesses the key to all learning, the talisman that will apply to all cases, in that one holy book, the Koran. This is his complete pharmacopoeia: his medicine chest, combining purgatives, blisters, sudorifies, styptics, narcotics, emetics, and all that the most profound M.D. could prescribe. With this "multum in parvo" stock-in-trade the Faky receives his patients. No. 1 arrives, a barren woman who requests some medicine that will promote the blessing of childbirth. No. 2, a man who was strong in his youth, but from excessive dissipation has become useless. No. 3, a man deformed from his birth, who wishes to become straight as other men. No. 4, a blind child. No. 5, a dying old woman, carried on a litter; and sundry other impossible cases, with others of a more simple character. The Faky produces his book, the holy Koran, and with a pen formed of a reed he proceeds to write a prescription--not to be made up by an apothecary, as such dangerous people do not exist; but the prescription itself is to be SWALLOWED! Upon a smooth board, like a slate, he rubs sufficient lime to produce a perfectly white surface; upon this he writes in large characters, with thick glutinous ink, a verse or verses from the Koran that he considers applicable to the case; this completed, he washes off the holy quotation, and converts it into a potation by the addition of a little water; this is swallowed in perfect faith by the patient, who in return pays a fee according to the demand of the Faky. As few people can read or write, there is an air of mystery in the art of writing which much enhances the value of a scrap of paper upon which is written a verse from the Koran. A few piastres are willingly expended in the purchase of such talismans, which are carefully and very neatly sewn into small envelopes of leather, and are worn by all people, being handed down from father to son.
