During the present year, I have been using formaldehyde in a peculiar manner for the prevention of catarrhal conditions. I add enough of the solution to a pail of water, so that the vapor in the rooms will not be irritating, and this is added to the water in the water chamber of my furnace, and from the heat of the furnace, is vaporized and diffused uniformly throughout the entire house.
I am convinced that it exercises an active influence in preventing the occurrence of catarrh, whether nasal or bronchial, and the many forms of cold which occur with the opening of winter.
