To give still greater completeness to the disinfection required for an infected apartment and thick woolen stuffs, carpets, etc., to which boiling heat cannot be applied, fumigate with sulphurous acid, thus: Arrange to vacate room for twelve hours; close every window and aperture, and upon an iron kettle with legs, burn a few ounces of sulphur; the quantity required for effectual work will depend upon cubical space of the apartment, and there should be enough to burn rapidly until want of oxygen in the air shall extinguish the flame. Instantly after kindling it, every person must withdraw from the place, and the room must remain closed for the succeeding eight hours. After this time the windows should be thrown open, and when the fumes have disappeared, all the wood work and walls should be thoroughly washed with soft soap and water, to which carbolic acid has been added (one pint of the common liquid to three or four gallons of water), and the paper from the walls stripped off. In whitewashed rooms, the walls should be scraped, and then washed with hot imewater to which carbolic acid has been added. The windows should be kept open for forty-eight hours. - Dunglison's Ref.
