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.
Fleas.-“Italian flea-powder,” sold in the East, is really efficacious. It is the powdered “Piré 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.”
