Metallic, metal-lined, or air-tight coffins should be used when possible; certainly when the body is to be transported for any considerable distance. _Comments._ SECTION I. 1. Copperas, also called green vitriol. 2. About four tablespoonfuls of the zinc and two tablespoonfuls of the salt, making a solution of the chloride of zinc. SECTION II. 1. The windows should be kept open, if possible, but in such a way as to avoid draughts on the bed. A fire should be constantly burning in an open fireplace. The room should be on the top floor, and all cracks and openings communicating with other rooms should be closed tightly. The door which has to be used should have a wet sheet hanging entirely over it, the windows and fireplace being alone relied on for ventilation. 2. The burning of sulphur produces sulphurous acid, which is an irrespirable gas. The person who lights the sulphur must, therefore, immediately leave the room, and after the lapse of the proper time, must hold his breath as he enters the room to open the windows and let out the gas. After fumigation, plastered walls should be whitewashed, the wood-work well scrubbed with carbolic soap, and painted portions repainted. 3. Or put copperas in a pail of water, in such quantity that some may constantly remain undissolved at the bottom. This makes a saturated solution. To every privy or water-closet, allow one pint of the solution for every four persons when cholera is about. To keep privies from being offensive, pour one pint into each seat, night and morning. 4. (_a._) Such articles should never be sent to a public laundry or mingled with the family washing. (_b._) The cutting open of stuffed articles may seem unnecessary, but it is not. The poison of contagious diseases clings to such stuffs (called =fomites=) with great tenacity for years, and must be destroyed before they are fit to be used again. 5. It is also well to fill a large wad of cotton or fine shavings with coal-tar powder or chloride of lime and place it beneath the hips, to absorb fluids. Contagious diseases are often caught at the funerals of those who have died of them, and the sanitary code of New York city forbids a public funeral of any person who has died of small-pox, diphtheria, scarlet fever, yellow fever, typhus fever, or Asiatic cholera. It is better to limit the attendance at such funerals to as few as possible. _Additional Precautions in Special Diseases._ =Small-pox.=—Every one in the vicinity should be vaccinated with fresh virus. Every person should be vaccinated in infancy, again after puberty, and again within four days after exposure to small-pox. Special care should be paid to isolation. Inmates of the house should neither make nor receive visits while the patient is sick.
