If a traveller finds that he is as well after having been some time in this country as he was before entering it, his best way is to make no innovation in his regimen, further than abating something in the quantity. But if he is of a tender constitution, he cannot act more wisely than to follow implicitly the regimen of sober healthy people of the country, without arguing upon European notions, or substituting what we consider succedaneums to what we see used upon the spot. All spirits are to be avoided; even bark is better in water than in wine. The stomach being relaxed by profuse perspiration, needs something to strengthen, not to inflame, and enable it to perform digestion. For this reason (instinct we should call it, if speaking of beasts) the natives of all eastern countries season every species of food, even the simplest and mildest rice, so much with spices, especially with pepper, as absolutely to blister a European palate. These powerful antiseptics providence has planted in these countries for this use; and the natives have, from the earliest time, had recourse to them. And hence, in these dangerous climates, the natives are as healthy as we are in our northern ones. Our author lays it down, then, as a positive rule of health, that the warmest dishes the natives delight in are the most wholesome strangers can use in the putrid climates of Lower Arabia, Abyssinia, Sennaar, and Egypt itself; and that spirits, and all fermented liquors, should be regarded as poisons; and, for fear of temptation, not so much as be carried along with you, unless as a menstruum for outward applications. Spring or running water, if you can find it, is to be your only drink. You cannot be too nice in procuring this article. But as, on both coasts of the Red Sea, you scarcely find any but stagnant water, the way which our traveller practised, when at any place that allowed time and opportunity, was always this: he took a quantity of fine sand, washed it from the salt quality with which it was impregnated, and spread it upon a sheet to dry; he then nearly filled an oil-jar with water, and poured into it as much from a boiling kettle as would serve to kill all the animalcula and eggs that were in it. He then sifted the dried sand, as slowly as possible, upon the surface of the water in the jar, till the sand stood half a foot at the bottom of it; after letting it settle at night, he drew it off by a hole in the jar with a spigot in it, about an inch above the sand; then threw the remaining sand out upon the cloth, and dried and washed it again. This process is sooner performed than described. The water is as limpid as the purest spring, and little inferior to the finest Spa. Drink largely of this without fear, according as your appetite requires. By violent perspiration the aqueous part of your blood is thrown off; and it is not spirituous liquor that can restore this, whatever momentary strength it may give you from another cause.
