§ Mr. ERNEST EVANS
asked the Lord President of the Council, in the case of Diesel oil extracted from British coal for high-speed engines, how much per cent. of the final product is the fraction extracted from the coal and how much per cent. is made up of imported oil?
§ Mr. R. MacDONALD
In cases in which imported petroleum oils are added to oils obtained from coal, the proportions vary within wide limits. Experiments are, however, proceeding with fuels consisting of 98–99 per cent. of coal-oil without any admixture of imported oils.
