or Camphire (see Encycl.), is, in China, obtained by boiling the branches, twigs, and leaves, of the Laurum-Camphora in water, upon the surface of which it is found swimming in the form of an oil, or adhering, in a glutinous form, to a wooden rod, with which the boiling matter is constantly stirred. The glutinous mass is then mixed with clay and lime, and put into an earthen vessel, with another of the same size properly fitted over it; the lower vessel being placed over a slow fire, the camphor gradually sublimes through the clay and lime, and adheres to the sides of the upper vessel.
