These are all the instruments you require. They should be kept scrupulously clean, and wrapped up in small pieces of chamois leather when put away. The dressings you require are these: Sal alembroth gauze. This is absorbent gauze impregnated with perchloride of mercury. It is coloured blue to distinguish it from other kinds of gauze. We have described how it is used for dressing wounds. It is an excellent material with which to dress any abrasion or cut or raw surface. We are not going to allow you to have any poisons in your box, except carbolic acid. We must allow this, for it is indispensable. Oh, it is not that we do not trust you with poisons; but no one who is not a physician ought to keep poisons in her house, for you never know who may meddle with them. And besides, you can never get a sufficient knowledge of drugs to enable you to use any of the poisons with safety. Of course, perchloride of mercury is a very powerful poison, and so we suppose that sal alembroth gauze is too; but it is quite safe to keep it, and it can no more be called a poison than can lead water-pipes or silver spoons. The second dressing you require is lint. This is very useful for many purposes, such as for spreading ointment upon or for making fomentations. Then you want cotton wool. Either the best white absorbent wool or else the blue wool—the companion to sal alembroth gauze. For bandages keep white calico ones, eight yards long, and two and one inches broad. Just a little piece of sticking-plaster to keep dressings upon the face, where bandaging is difficult, and a fair-sized piece of either oiled silk or green protective to cover over fomentations, complete the list. A half-pint bottle of carbolic acid dissolved in water (1 in 20) is the first application required. Then you want about an ounce of powdered boracic acid for dressing wounds; and an ounce pot of boracic acid and eucalyptus ointment. To allay the pain of bruises do not use tincture of arnica; but apply the following lotion on a piece of uncovered lint: one part of spirit and one part of solution of acetate of ammonia (B.P.) to eight parts of water. When the pain of a bruise has been allayed, the absorption of the residual swelling and discoloration may be hastened by gentle massage. So much for the surgical requisites. We are of opinion that the less you have to do with drugs the better. People cannot understand that if a drug has a powerful action in disease—if, for instance, a drug will stop convulsions—it will have an action if given to a perfectly healthy person, and that action will do harm to the body. The drugs which we advise you to keep in your medicine chest are all perfectly safe; but at the same time they all have definite actions. The liquids should be kept in half-ounce bottles. They should be labelled with the names of the drugs, their doses, and the complaints for which they are used.
