Nº. 66.
Take of Oil of Roses one Pound; of red Lead half a Pound; of Vinegar four Ounces. Boil them together nearly to the Consistence of a Plaister; then dissolve in the liquid Mass an Ounce and a Half of yellow Wax, and two Drachms of Camphor, stirring the whole about well. Remove it then from the Fire, and spread it on Sheets or Slips of Paper, of what Size you think most convenient. The Ointment of Chambauderie, so famous in many Families on the Continent, is made of a Quarter of a Pound of yellow Wax, of the Plaister of three Ingredients (very nearly the same with [Nº. 66]) of compound Diachylon and of common Oil, of each the same Quantity, all melted together, and then stirred about well, after it is removed from the Fire, till it grows cold. To make a Sparadrap, or Oil Cloth, which is Linen, covered with, or dipt in an emplastic Substance or Ointment, it must be melted over again with the Addition of a little Oil, and applied to the Linen as directed at [Nº. 65.]
