Why don't YOU rather, with your practical power, turn sanitary reformerthe only true soldierand conquer those real devils and "natural enemies" of Englishmen, carbonic acid and sulphuretted hydrogen?' 'Ce n'est pas mon metier, my dear fellow.

They retain the hydrogen and the carbon, exhale the superfluous oxygen, and absorb little or no nitrogen.

Thus, Bacillus amylobacter (Fig. 2, II.), as Mr. Van Tieghem has shown, subsists upon the hydrocarbons contained in plants, and disorganizes vegetable tissues in disengaging hydrogen, carbonic acid, and vegetable acids.

You feed them pure hydrogen or a hydrocarbon fuel; you get electricity, heat, and water.

This is about 50° lower than the amount found by calculation from our most rapid radiation; and as this amount is produced in a few hours, it is not too much to expect that, when continued for more than two weeks (the lunar night), it might reach a temperature sufficient to liquefy hydrogen (60° F. abs.), or perhaps even below it.

These beads and bubbles are pure oxygen, which the plants distil from the water itself, in order to obtain its hydrogen, and from carbonic acid, in order to obtain its carbon.

In mentioning the constituents of the atmosphere, he adopts without explanation the loose statement of some of the books, placing carburetted hydrogen on the same footing as to constancy and amount with carbonic acid, and making no allusion to nitric acid.

Sometimes Mona would be of the party, and nothing pleased Agnes or her better than such wonderful things as these; while Willie found it very amusing to hear Agnes, who was sharp enough to pick up not a few of the chemical names, dropping the big words from her lips as if she were on the most familiar terms with the things they signifiedphosphuretted hydrogen, metaphosphoric acid, sesquiferrocyanide of iron, and such like.

CHARLES, a French physicist, born at Beaugency; was the first to apply hydrogen to the inflation of balloons (1746-1823).

They will carefully distill itextract its valuable juicesand will supply for combustion only its carbureted hydrogen and its carbon in some gaseous or finely divided form.

It is a remarkable circumstance in its constitution, that it contains no hydrogen, and that it consists merely of carbon and oxygenthere being twice as much oxygen as there is carbon.
