The latter observer found the gases given off tion of gas by coal from the district of Newcastle and Durham evolved by to contain carbonic acid, marsh gas or light carburetted coal.
It has been supposed that this theory was suggested to him either by researches on olefiant gas and carburetted hydrogen or by analysis of "protoxide and deutoxide of azote," both views resting on the authority of Dr Thomas Thomson (1773-1852), professor of chemistry in Glasgow university.
Thus iron, at least highly carburetted, i.e.
One of the most generally adopted methods of enrichment now is by means of carburetted water gas mixed with poor coal gas.
This form of apparatus has been very generally adopted in Great Britain as well as in America, and practically all carburetted water-gas plants are founded upon the same set of actions.
