which may be considered as a type of pestilential fever generally, usually sets in sixteen days after exposure to the malaria; and that one attack, instead of acclimatising the patient, seems to render him all the more liable to a second. Every conceivable precaution known in those days, had been taken to ensure the health of the crew of the 'Albert.' A great discovery of modern days is the power of quinine to keep off many types of fever. A person would, now, have little to fear in taking a passage in a Niger steamer; supposing that vessels ran regularly up that river. The quinine he would take, beginning at the coast, would render him proof against fever, until he had passed the delta; but nothing would remove the risk of a long sojourn in the delta itself. However, I should add that Dr. Livingstone's experience on the zambesi throws doubt on the power of quinine to keep off the type of fever that prevails upon that river.
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.
Thirst.--Pour water over the clothes of the patient, and keep them constantly wet; restrain his drinking, after the first few minutes, as strictly as you can summon heart to do it. (See "Thirst" in the chapter on "Water.") In less severe cases, drink water with a tea-spoon; it will satisfy a parched palate as much as if you gulped it down in tumblerfuls, and will disorder the digestion very considerably less.
Hunger.--Give two or three mouthfuls, every quarter of an hour, to a man reduced to the last extremity by hunger; strong broth is the best food for him.
Poisoning.--The first thing is to give a powerful emetic, that whatever poison still remains unabsorbed in the stomach, may be thrown up. Use soap-suds or gunpowder (see Emetics) if proper emetics are not at hand. If there be violent pains and gripings, or retchings, give plenty of water to make the vomitings more easy. Next, do your best to combat the symptoms that are caused by the poison which was absorbed before the emetic acted. Thus, if the man's feet are cold and numbed, put hot stones against them, and wrap them up warmly. If he be drowsy, heavy, and stupid, give brandy and strong coffee, and try to rouse him. There is nothing more to be done, save to avoid doing mischief.
Fleas.--"Italian flea-powder," sold in the East, is really efficacious. It is the powdered "Pire oti" (or flea-bane), mentioned in Curzon's 'Armenia' as growing in that country; it has since become an important article of export. A correspondent writes to me, "I have often found a light cotton or linen bag a great safeguard against the attacks of fleas. I used to creep into it, draw the loop tight round my neck, and was thus able to set legions of them at defiance."
Vermin on the Person.--I quote the following extract from Huc's 'Travels in Tartary':--"We had now been travelling for nearly six weeks, and still wore the same clothing we had assumed on our departure. The incessant pricklings with which we were harassed, sufficiently indicated that our attire was peopled with the filthy vermin to which the Chinese and Tartars are familiarly accustomed; but which, with Europeans, are objects of horror and disgust. Before quitting Tchagan-Kouren, we had bought in a chemist's shop a few sapeks'-worth of mercury. We now made with it a prompt and specific remedy against the lice. We had formerly got the receipt from some Chinese; and, as it may be useful to others, we think it right to describe it here. You take half an ounce of mercury, which you mix with old tea-leaves previously reduced to paste by mastication. to render this softer, you generally add saliva; water could not have the same effect. You must afterwards bruise and stir it a while, so that the mercury may be divided into little balls as fine as dust. (I presume the blue pill is a pretty exact equivalent to this preparation.) You infuse this composition into a string of cotton, loosely twisted, which you hang round the neck; the lice are sure to bite at the bait, and they thereupon as surely swell, become red, and die forthwith. In China and in Tartary you have to renew this salutary necklace once a month."
Blistered Feet.--To prevent the feet from blistering, it is a good plan to soap the inside of the stocking before setting out, making a thick lather all over it. A raw egg broken into a boot, before putting it on, greatly softens the leather: of course the boots should be well greased when hard walking is anticipated. After some hours on the road, when the feet are beginning to be chafed, take off the shoes, and change the stockings; Putting what was the right stocking on the left foot, and the left stocking on the right foot. Or, if one foot only hurts, take off the boot and turn the stocking inside out. These were the plans adopted by Captain Barclay. when a blister is formed, "rub the feet, on going to bed, with spirits mixed with tallow dropped from a candle into the palm of the hand; on the following morning no blister will exist. The spirits seem to possess the healing power, the tallow serving only to keep the skin soft and pliant. This is Captain Cochrane's advice, and the remedy was used by him in his pedestrian tour." (Murray's Handbook of Switzerland.') The recipe is an excellent one; pedestrians and teachers of gymnastics all endorse it.
Rarefied Air, effects of.--On high plateaux or mountains new-comers must expect to suffer. The symptoms are described by many South American travellers; the attack of them is there, among other names, called the puna. The disorder is sometimes fatal to stout plethoric people; oddly enough, cats are unable to endure it: at villages 13,000 feet above the sea, Dr. Tschudi says that they cannot live. Numerous trials have been made with these unhappy feline barometers, and the creatures have been found to die in frightful convulsions. The symptoms of the puna are giddiness, dimness of sight and hearing, headache, fainting-fits, blood from mouth, eyes, nose, lips, and a feeling like sea-sickness. Nothing but time cures it. It begins to be felt severely at from 12,000 to 13,000 feet above the sea. M. Hermann Schlagintweit, who has had a great deal of mountain experience in the Alps and in the Himalayas, up to the height of 20,000 feet or more, tells me that he found the headache, etc., come on when there was a breeze, far more than at any other time. His whole party would awake at the same moment, and begin to complain of the symptoms, immediately on the commencement of a breeze. The symptoms of overwork are not wholly unlike those of the puna, and many young travellers who have felt the first, have ascribed them to the second.
Scurvy has attacked travellers even in Australia; and I have myself felt symptoms of it in Africa, when living wholly on meat. Any vegetable diet cures it: lime-juice, treacle, raw potatoes, and acid fruits are especially efficacious. Dr. Kane insists on the value of entirely raw meat as a certain anti-scorbutic: this is generally used by the Esquimaux.
Haemorrhage from a Wound.--When the blood does not pour or trickle in a steady stream from a deep wound, but jets forth in pulses, and is of a bright red colour, all the bandages in the world will not stop it. It is an artery that is wounded; and, unless there be some one accessible, who knows how to take it up and tie it, I suppose that the method of our fore-fathers is the only one that can be used as you would for a snake-bite (see next paragraph); or else to pour boiling grease into the wound. This is, of course, a barbarous treatment, and its success is uncertain, as the cauterised artery may break out afresh; still, life is in question, and it is the only hope of saving it. After the cautery, the wounded limb should be kept perfectly still, well raised, and cool, until the wound is nearly healed. A tourniquet, which
