Coal far gas copied from Litteraty Gazette of April 18 - 1835

We have to congratulate the country on a discovery, by means of which that superabundant refuse, Coal-Far, will be extensively used in the production of a splendid light. This invention occured to M^r. Beale during his experiments to render the spirit obtained from caoutchouc available for public and domestic lighting.

The Coal Far is not very inflammable ; but when lighted produces in burning a dull sort of "darknefs visible" flame, and abundance of murky smoke. For the new lamp, there is a small circular trough, like a tea-cup, with a tube through it, and the tar is supplied to this vefsel from a close tin cannister, as it is consumed in burning. After the far is lighted, the circular tar-trough is covered by another cup which exactly fits on the outer rim of it, and would act as an extinguisher ; but that there is an hole through the bottom of this cover, from which a short length of conical pipe descends about an inch, and up this pipe the smoke of the burning tar has to ascend ; but this smoke is entirely consumed, and made to produce a most brilliant flame by a jet of air, which is forced up a very small pipe, rising through the hole in the centre of the tar-trough ; the orifice of which air-pipe is a little above the level of the burning tar.
