For medicines not much is needful; but in case of emergencies take sulphate of zinc (1 per cent. solution) for the eyes; quinine (5-10 grs. for fever, ½ p. c. sol. alone, or mixed with the previous, for eyes); carbolic acid (1 to 3 of oil for scrapes and cuts, &c.), and any special remedies needed. In general, diet is the main matter; aperients are needless with plenty of native bread and cooked tomatoes; and, on the other hand, if necessary, live on rice (very well boiled with a large amount of water), and avoid fat and sugar. The less clothing is used by day, and the more at night, the better; the clear nights are usually down to freezing in the winter, even far up the Nile, while the day may be 70° to 80°. The main matter is to avoid being out at sunset; or at least keep moving then, and avoid any chill, as fever is generally caught at that time. All drinking water should be boiled thoroughly; excepting perhaps when taken from the middle of the Nile, and not just below a town. For a trip up the Nile the most thorough way is to take a small native boat, with a cabin on it, entirely to yourself, or with only a like-minded companion. Such a boat can generally be found at the main towns, Cairo, Minia, Assiut, &c.; when more pretentious, with several cabins, it ranks as a _dahabyieh_. The boat should be hired with a written English, French, or Italian agreement in duplicate, some European shopkeeper known to the boatman serving as his translator, to assure him of the terms. The actual terms of a boat I hired at Minia were ‘A. B. agrees to hire a boat with cabin from C. D., with a reis, two sailors, and boy, at ten francs per day. Ten days’ hire guaranteed; after that by the day. To be discharged anywhere below the first cataract (Assuan) without any return pay. No food provided. Payments to be made as demanded, taking receipts.’ If they dawdle, and it is needful to push on quicker, a promise, of say 50 francs on reaching the terminus by a certain day, less 5 francs a day for all time after that, will be effectual. Always stay for the night above a town or village, for the sake of cleaner water.
