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 will stop the blood for a time, is made by tying a strong thong, string, or handkerchief firmly above the part, putting a stick through, and screwing it tight. If you know whereabouts the artery lies, which is the object to compress, put a stone over the place under the handkerchief. The main arteries follow pretty much the direction of the inner seams of the sleeves and trousers.

Snake-bites.--Tie a string tight above the part, suck the wound, and caustic it as soon as you can. Or, for want of caustic, explode gunpowder in the wound; of else do what Mr. Mansfield Parkyns well suggests, i.e., cut away with a knife, and afterwards burn out with the end of your iron ramrod, heated as near a white heat as you can readily get it. The arteries lie deep, and as much flesh may, without much danger, be cut or burnt into, as the fingers can pinch up. The next step is to use the utmost energy, and even cruelty, to prevent the patient's giving way to that lethargy and drowsiness which is the usual effect of snake-poison, and too often ends in death.

Wasp and Scorpion-stings.--the Oil scraped out of a tobacco-pipe is a good application; should the scorpion be large, his sting must be treated like a snake-bite.

Broken Bones.--It is extremely improbable that a man should die, in consequence of a broken leg or arm, if the skin be uninjured; but, if the broken end forces its way through the flesh, the injury is a very serious one. Abscesses form, the parts mortify, and the severest consequences often follow. Hence, when a man breaks a bone, do not convert a simple injury into a severe one, by carrying him carelessly. If possible, move the encampment to the injured man, and not vice versa. Mr. Druitt says:--"When a man has broken his leg, lay him on the other side, put the broken limb exactly on the sound one, with a little straw between, and tie the two legs together with handkerchiefs. Thus the two legs will move as one, and the broken bone will not hurt the flesh so much, nor yet come through the skin."

Drowning.--A half-drowned man must be put to bed in dry, heated clothes, hot stones, etc., placed against his feet, and his head must be raised moderately. Human warmth is excellent, such as that of two big men made to lie close up against him, one on each side. All rough treatment is not only ridiculous but full of harm; such as the fashion--which still exists in some places--of hanging up the body by the feet, that the swallowed water may drain out of the mouth.
