Not illustrated. 1852 Excerpt: ... new coal-formation of the lias, there issues, probably from the highly carboniferous shale, a gas which burns with a bluish flame, yellow at the apex, and, after being freed from carbonic acid, is found to contain 79-10 per cent, of marsh-gas, 16-11 olefiant gas, and 4-79 of an incombustible gas, probably nitrogen, but neither carbonic oxide, nor any vapour condensable by oil of vitriol. (Bischof.) 3. Marsh-gas likewise issues from the earth in places more or less removed from coal-strata. From the argillaceous banks of a stream at Bedlay, 7 English miles from Glasgow, and at least three from the coalformation, there issues a mixture of 87'5 vol. marsh-gas and 12-5 air, which, if set on fire, continues to burn with a yellow flame for five weeks; the gas issues in largest quantity and with greatest force from the stream itself. (Th. Thomson, N.Ed. Phil. J. 1, 67.)--The gas which maintains the Sacred Fire of Baku, is marsh-gas, mixed with 6 per cent, of nitrogen, and from 1 to 5 per cent, of carbonic acid, also with vapour of rock-oil; hence the gas, when analyzed by means of oxide of copper ignited in a tube, yields too much carbon (77-5C and 22'5H). (Hess, J. pr. Chem. 13, 514.)--IT A remarkable evolution of gas from the earth has been observed at the village of Charlemont, in Staffordshire; a workman was led to the discovery of it by the absence of all vegetation near the spot. By fixing tubes in the ground, he obtained a constant stream of gas, which burned with a clear pale bluish flame, giving both light and heat. He likewise found a similar issue of gas at his cottage, 150 yards distant from the place where he first observed it; and the supply was so abundant, that no perceptible diminution took place, even after the gas had been burnt for several wee...
