If I were to put the bit of chalk with which we started into the hot but obscure flame of burning hydrogen, it would presently shine like the sun.

This substance is a true vegetable oxyd, with two bases, composed of hydrogen and carbon, brought to the state of an oxyd by means of a certain proportion of oxygen; and these three elements are combined in such a way that a very slight force is sufficient to destroy the equilibrium of their connection.

And he tells us that wood can become lignite, or wood-coal, by parting with its oxygen, in the shape of carbonic acid gas, or choke-damp; and then common or bituminous coal, by parting with its hydrogen, chiefly in the form of carburetted hydrogenthe gas with which we light our streets.

For in the wood-coal a great deal of the hydrogen still remains.

In mines of true coal, not only is choke-damp given off, but that more terrible pest of the miners, fire-damp, or explosive carburetted hydrogen and olefiant gases.

Now the occurrence of that fire-damp in mines proves that changes are still going on in the coal: that it is getting rid of its hydrogen, and so progressing toward the state of anthracite or culmstone-coal as it is sometimes called.

If we conceive the anthracite cleared of all but its last atoms of oxygen, hydrogen, and nitrogen, till it has become all but pure carbon, it would becomeas it has become in certain rocks of immense antiquity, graphitewhat we miscall black-lead.

The Prussic acid (by some called hydrocyanic acid) is a liquid, extracted from vegetables, and contains one part of cyanogen and one part of hydrogen.

Are there not tabloids that supply the body with oxygen, hydrogen, calorics, or whatever else is essential to life in the common hundredweights and gallons of bread, meat, and drink?

Sometimes from that resplendent sheen A new light gleams across the void, And, awe-struck, we conceive the scene Of two vast solar orbs destroyed; By fearful impact changed again, Unnumbered miles beyond our ken, To leagues of blazing hydrogen.

New here is the cohesion-series of Steffens (the phenomenon of magnetism), in which nitrogen forms the south pole, carbon the north pole, and iron the point of indifference, while oxygen, hydrogen, and water represent the east pole, west pole, and indifference point in electrical polarity.

It contains, accordingly, a volume of gas equal to about 320 cubic feet, which, in pure hydrogen, would enable it to support a weight of twenty-one pounds, which is about its real power when recently inflated, and before the gas has had time to become deteriorated by the process of endosmose.[B]

As, however, it would be very expensive to inflate such a vessel with pure hydrogen gas, it would be advisable to found our calculations upon the use of coal gas; under which circumstances the weight it would carry would be limited to about three tons.

When I am hungry I promenade myself to the butcher's and bring home a pound or so of steak, which I cook very nicely in three seconds by this oxy-hydrogen flame.

Under the action of chlorophyll and sunlight these substances are split up, the carbon, oxygen and hydrogen being combined into plant food.

The first part of the process is well illustrated by the small experiments now shown; the organic matter in suspension and in solution separates into flocculent particles, which rise to the top of the liquid and remain until the bubbles of hydrogen which have carried them up escape, when the solid matter will precipitate.

The absence of sulphureted hydrogen in samples of unfiltered effluent, which have been kept for about six weeks in stoppered bottles, is also a fact of importance.

"Acetylene, as you may know," he hastily explained, never pausing for a moment in his work, "is composed of carbon and hydrogen.

As it burns at the end of the nozzle it is broken into carbon and hydrogenthe carbon gives the high temperature, and the hydrogen forms a cone that protects the end of the blowpipe from being itself burnt up.

BENZENE, a substance compounded of carbon and hydrogen, obtained by destructive distillation from coal-tar and other organic bodies, used as a substitute for turpentine and for dissolving grease.

OXYGEN, a colourless, inodorous gas which constitutes one-fifth in volume of the atmosphere, and which, in combination with hydrogen, forms water.
