It was astonishing how quickly the carbon in the sugar was absorbed by the system and came to the relief of smoldering bodily fires.

Only it is necessary that they should be supplied with a different kind of raw material; as they cannot extract carbon from carbonic acid, they must be furnished with something else that contains carbon.

But Fabroni, full of the then novel conception of acids and bases and double decompositions, propounded the hypothesis that sugar is an oxide with two bases, and the ferment a carbonate with two bases; that the carbon of the ferment unites with the oxygen of the sugar, and gives rise to carbonic acid; while the sugar, uniting with the nitrogen of the ferment, produces a new substance analogous to opium.

" All the above named scientific men agree that variations of a current passing through a carbon microphone are produced by pressure of the carbons against one another, and they also agree that a jolting motion could not be relied upon to reproduce articulate speech.

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

"It's a good deal as though Michael Angelo, when he made one of his sketches, white on black, put a sheet of carbon under his paper and made a copy at the same time, black on white.

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.

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.

Carbon to Nitrogenous.

SUGAR Chemically, sugar is a compound belonging to the group of carbohydrates, or organic compounds of carbon with oxygen and hydrogen.

We know that an animal breathes in oxygen, that the oxygen unites with particles of carbon within the body and that the resulting carbonic acid gas is exhaled.

of oxygensince to saturate a pound of carbon by the formation of carbonic acid, requires 2-2/3 lbs.

* * PLASTIC CARBON FOR BATTERIES.

These couplings secure a good contact, and, by their dimensions, prevent the attachments from becoming hot and consequently injuring the carbon at this point.
