How to divide and subdue it so as to render it suitable for house lighting, was still a difficult problem. Farmer, Sawyer, Mann, and Edison, all attacked it at nearly the same time, going back with singular accord from the voltaic arc principle to that of incandescence in a vacuum. Edison, the prodigy of the century in inventive genius, was the most successful.
This conductor was a strip of carbonized paper about an inch long, one-sixteenth of an inch broad, and six or seven one-thousandths of an inch thick, the ends of which were secured to clamps that formed the poles of a battery. The carbon was lighted up to incandescence, and, of course, oxidized and disintegrated immediately.
I agree with The Dictator that poetry is little more than the ashes of passion; still it may show that the flame has had its sweep where you find it, unless, indeed, it is shoveled in from another man's fireplace." "What do you say to the love poetry of women?" asked the Professor. "Did ever passion heat words to incandescence as it did those of Sappho?"
There came a rush of little feet; soft, fragrant draperies brushed my face; dimly I watched Lakla bend over the Irishman. She straightened her arms swept out and the writhing vine, with its tendrilled heads of ruby bloom, five flames of misty incandescence, leaped into the faces of the soldiers now close upon us.
But it didn't look like that to the naked eye. It was just a tiny speck of incandescence gliding with grave deliberation across the sky. It was a sliver of sunlight, moving as they watched. There were a good many millions of people watching it, just then, as it floated aloft in emptiness.
In order to bring a refractory body inclosed in a bulb to incandescence, it is desirable, on account of economy, that all the energy supplied to the bulb from the source should reach without loss the body to be heated; from there, and from nowhere else, it should be radiated.
But the thing had been there, nonetheless, and the ship had hit it at high velocity. Fortunately, the ship had only touched the edge of the swirling cloud, otherwise the entire ship would have vanished in a puff of incandescence. But it had done enough.
Nor was the pirate unarmed a vicious flare of incandescence leaped from his Lewiston, to spend its force in spitting, crackling pyrotechnics against the ether-wall of the squat and monstrous Standish. But Costigan's infernal machine did not rely only upon vibratory destruction.
But whichever view we may adopt, it is at least obvious that the earth is in part, at all events, a heated body, and that the heat is not in the nature of a combustion, generated and sustained by the progress of chemical action. No doubt there may be local phenomena of this description, but by far the larger proportion of the earth's internal heat seems merely the fervour of incandescence.
And hence, if there is one mass which was not only formed after the rest, but exceeds them enormously in size, it follows that this one will reach an intensity of incandescence far beyond that reached by the rest; and will continue in a state of intense incandescence long after the rest have cooled. Such a mass we have in the Sun.
