Precautions in unhealthy Places.--There are certain precautions which
should be borne in mind in unhealthy places, besides that which I have
just mentioned of regularly taking small doses of quinine, such as never
to encamp to the leeward of a marsh; to sleep close in between large
fires, with a handkerchief gathered round your face (natural instinct
will teach this); to avoid starting too early in the morning; and to
beware of unnecessary hunger, hardship, and exposure. It is a
widely-corroborated fact that the banks of a river and adjacent plains
are often less affected by malaria than the low hills that overlook them.
Diarrhoea.--With a bad diarrhoea, take nothing but broth, rice water, and
it may be rice, in very small quantities at a meal, until you are quite
restored. The least piece of bread or meat causes an immediate relapse.
Ophthalmia'.--Sulphate of zinc is invaluable as an eyewash: for
ophthalmia is a scourge in parts of North and South Africa, in Australia,
and in many other countries. The taste of the solution which should be
strongly astringent, is the best guide to its strength.
Tooth-ache.--Tough diet tries the teeth so severely, that a man about to
undergo it, should pay a visit to a dentist before he leaves England. An
unskilled traveller is very likely to make a bad job of a first attempt
at tooth-drawing. By constantly pushing and pulling an aching tooth, it
will in time loosen, and perhaps, after some weeks, come out.
