If a number of jets of air be admitted into aheated inflammable atmosphere, as the body of a furnace, itscombustion will be attained in such a way as to produce a greatincrease of heat, and, as a necessary consequence, destroy thesmoke. In some of the large gardens of Europe, as will as in somemanufactories, attempts have been made to consume the smokeor gases of the furnaces, by bringing them in contact with a bodyof glowing incandescent fuel, producing a result the reverse ofwhat was expected, namely, the absorptioQ of heat by theirexpansion and decomposition, instead of giving out heat by theircombustion. It is strange that this erroneous notion should bepersisted in, even at the present day, when any chemical workof good authority would satisfy any one wishing for such knowl-edge that decomposition^ not combustion, is the effect of a hightemperature being applied to hydro-carbon-gases; â
