th, it can at any time be replaced by twisting up
a paper cartridge. I would further suggest that the powders be
differently coloured, one colour being used for emetics and another for
aperients.

Lint, to make.--Scrape a piece of linen with a knife.

Ointment.--Simple cerate, which is spread on lint as a soothing plaister
for sores, consists of equal parts of oil and wax; but lard may be used
as a substitute for the wax.

Seidlitz-powders are not often to be procured in the form we are
accustomed to take them in, in England; so a recipe for making 12 sets of
them, is annexed:--1 1/2 oz. of Carbonate of Soda and 3 oz. of Tartarised
Soda, for the blue papers; 7 drachms of Tartaric Acid, for the white
papers.

Bush Remedies.--Emetics.--For want of proper physic, drink a charge of
gunpowder in a tumblerful of warm water of soap-suds, and tickle the
throat.

Vapour-baths are used in many countries, and the following plan, used in
Russia, is often the most convenient. Heat stones in the fire, and put
them on the ground in the middle of the cabin or tent; on these pour a
little water, and clouds of vapour are given off. In other parts of the
world branches are spread on hot wood-embers, and the patient is placed
upon these, wrapped in a large cloth; water is then sprinkled on the
embers, and the patient is soon covered with a cloud of vapour. The
traveller who is chilled or over-worked, and has a day of rest before
him, would do well to practise this simple and pleasant remedy.

Bleeding and Cupping'.--Physicians say, now-a-days that bleeding is
rarely, if ever, required; and that frequently it does much harm; but
they used to bleed for everything. Many savages know how to cup: they
commonly use a piece ofa horn as the cup, and they either suck at a hole
in the top of the horn, to produce the necessary vacuum, or they make a
blaze as we do, but with a wisp of grass.

Illnesses.--Fevers of all kinds, diarrhoea, and rheumatism, are the
plagues that most afflict travellers; ophthalmia often threatens them.
Change of air, from the flat country up into the hills, as soon as the
first violence of the illness is past, works wonders in hastening and
perfecting a cure.

Fever.--The number of travellers that have fallen victims to fever in
certain lands is terrible: it is a matter of serious consideration
whether any motives, short of imperious duty, justify a person in braving
a fever-stricken country. In the ill-fated Niger
