Abstract
AFTER a concise historical introduction, the authors deal with the distillation of coal and the manufacture of direct coal-tar products. In referring to the very small yield from coal of the principal colour-producing hydrocarbons, the possibility of a new source of these products from petroleum is mentioned. A more general conversion of coal into coke before consuming it as fuel would also lead to a further supply of these valuable hydrocarbons.
