The oleaginous group comprises all oily matters, which are even purer hydro-carbons than the first-mentioned class.

The total carbon was found to be: "cold-rolled," 1.108 per cent.; hardened, 1.128 per cent.; and annealed, 0.924 and 0.860 per cent.

The tube, B, was then placed in tube, A, the joint being made with fireclay, and to prevent the steam from carrying small particles of solid carbon into ore in the upper tube, the anthracite was divided from the ore by means of a piece of fine wire gauze.

MAXIM, HIRAM S., American inventor, born at Tangerville, Maine, U.S.; showed early a decided mechanical talent, and is best known in connection with the invention of the gun named after him, but among his other inventions are the smokeless powder, the incandescent lamp carbons, and search-lights; B. 1840.

In the dissociation of water into its hydrogen and oxygen, with the mingled carbon in a powdered state, we undoubtedly possess the elements of combustion that are unexcelled on earth, a heat-producing combination that in both activity and power leaves little to be desired this side of the production of the electric force and heat directly from the carbon without the intermediary of boilers, engines, dynamos, and furnaces.

In the Gerard incandescent lamp the carbons have the form of a V. They are obtained by agglomerating very finely powdered carbon, and passing it through a draw plate.

It is unconsumed carbon finely divided escaping into open air.

Soft coal comes nearer to amorphous carbon.

"There are full 1,700 forges engaged in the various branches of the trades, and of course as many fires, fixing oxygen to make their heat, and evolving the undecomposed carbon in active volumes of steam and smoke.

George put an ingot of bronze into a carbon crucible and gripped the edge of the crucible with long tongs.

Crystallized carbon has risen in the estimation of capitalists, and crystallized clay has gone down in the scale of value.
