 | | John Clayton, in an extract from a letter in the "Philosophical Transactions" for 1735, calls gas the "spirit" of coal; and discovered its inflammability by an accident. |
 | | This "spirit" happened to catch fire, by coming in contact with a candle, as it escaped from a fracture in one of his distillatory vessels. |
 | | In this year, 1817, at the three stations belonging to the Chartered Gas Company, 25 chaldron (24 m³) of coal were daily carbonized, producing 300,000 cubic feet (8,500 m³) of gas, which was equal to the supply of 75,000 Argand lamps, each yielding the light of six candles. |
