xxii I. PRELIMINARY INFORMATION. 7. Médical Hints.
Jan., 82° in Feb., and 91° in March. The mean minimum for thèse
four months is 55° ; and the relative humidity is 35 per cent by day,
49 per cent at night. Dew does not fall at Assuân. — Assuân is
more under the immédiate influence of the désert, but it is ex-
posed to a rather stronger wind than Luxor. The air is bracing, al-
though 3-6° warmer than at Luxor. The beauty of the surroundings
and the interest of the Cataract lend a pecuïiar charm to Assuân.
— The accommodation for invalids is very good. Two English
physicians and one German one are in résidence at Assuân in
winter. Résident nurses are also at hand.
Patients should not leave Upper Egypt until the third week in
March, on account of the cold N. wind, and should then travel by
railway. They will find at Beyrout, Athens, Corfu, Sicily, and
Capri and other points near Naples, admirable transition-stations
Médical Hints. As regards clothing, invalids must remember that
fiannel or woollen materials are désirable, as it is often very cold in
Egypt. A fur coat or similar garment is of use. Merino unrter-
clothing of thin and also of médium texture is required. Thin
merino choiera belts may be used by invalids to protect aflected
organs, but they are not required by healthy individuals, except in
case of emergency. Patients should be careful to pay attention to the
daily changes of température (p. lix). Warmer clothing or a cloak are
useful in the morning, then lighter clothing till nearly sunset, when
the cloak should be resumed. Most invalids should not leave the
hôtel (or, in certain cases, their bedrooms) before 10 a. m. The hour
for returning to the hôtel varies with the place and the month, being
earliest in Jan. and latest in March and April. If the patient be
guided by the relative humidity, it would be earliest at Mena House,
say about sunset ; a little later at Helwân ; at Luxor still later, 6 p. m.
(except in Jan.), and 8 p. m. in March; and latest of ail at Assuân,
— it being always understood that précautions as to extra clothing
hâve been taken. — Those who are not invalids, and in some cases
invalids also, may sleep with the Windows open with safety, but
travellers should be chary of doing so on board the steamboats.
There are good chemists at Alexandria, Cairo, Luxor, and As¬
suân, from wbom small medieine-chests adapted for the climate may
be purchased. The advice of the traveller's physician at home will
be useful in stocking such a medicine-chest. In serious cases of
illness a European doctor, when procurable, should always be con-
sulted, as tbe traveller's own expérience acquired at home is of little
avail in the climate of Egypt.
Diarrhœa, which is apt to develop into dysentery, is a very common
complaint in this climate, and is generally the resuit of catehing cold.
Early treatment by a physician will generally resuit in cutting short an
attack. The patient should first take a slight aperient, and afterwards
tincture of opium. A simple farinaceous diet will be bénéficiai while
fruit, méat, and fatty substances should be avoided. In some cases of
diarrhœa ail remédies are sometimes unavailing except change of climate
