Chloride tungsten or titanium passed through hot tube, depositing a film of metal on the carbon; or filaments of zirconia oxide, or alumina or magnesia, thoria or other infusible oxides mixed or separate, and obtained by moistening and squirting through a die, are thus coated with above metals and used for incandescent lamps.
The argument here employed is founded upon this fact; that, from the fusible species of coal, a caput mortuum may be formed by distillation, and that this chemical production has every essential quality, or every peculiar property, of the fixed and infusible species; although, from the circumstances of our operation, this caput mortuum may not have precisely the exterior appearance of the natural coal.
Red sandstone, passing in the upper part into a coarse, hard, red conglomerate, 300 feet thick, having a calcareous cement, and including grains of quartz and broken crystals of feldspar; basis infusible; the pebbles consist of dull purplish porphyries, with some of quartz, from the size of a nut to a man's head.
Thus we have one species of coal which is extremely fusible, abounds with oil, and consequently is inflammable; we have another species again which is perfectly fixed and infusible in the fire; therefore, we may conclude upon principle, that, however, both those coals must have undergone the operation of heat and fusion, in bringing them to their present state, it is only the last that has become so much evaporated as to become perfectly fixed, or so perfectly distilled, as to have been reduced to a caput mortuum.
Shaped like a toothpick, needle-pointed fore and aft, with ultra-stubby wings and vanes, with flush-set rocket ports everywhere, built of a lustrous silvery alloy of noble and almost infusible metals such was the private speedboat of the chief of the T. S. S. The fastest thing known, whether in planetary air, the stratosphere, or the vacuus depth of interplanetary space, her first flashing trial spins had won her the nickname of the Silver Sliver.
A cosmic flashed on the rock for an instant, and it was glowing, incandescent lava. The Ancient Mariner was buried under a hundred feet of rapidly solidifying rock, but rock which could be fused away from its infusible walls when the time came. "We're ready to go now get to work with the radio, Morey, when we get to Earth."
It will thus appear, that the regular form, and horizontal direction of strata throughout this country of coal, now under contemplation, has been broken and disordered by the eruption and interjection of those masses of basaltic stone or subterraneous lava; and thus may be explained not only the disorders and irregularities of coal strata, but also the different qualities of this bituminous substance from its more natural state to that of a perfect coal or fixed infusible and combustible substance burning without smoke.
From the infusible, though evaporable, diamond to nitrogen itself, the metallic nature of which has been long suspected by chemists, though still under the mistaken notion of an oxyde, we trace a series of metals from the maximum of coherence to positive fluidity, in all ordinary temperatures, we mean.
The marvelous new tubes that ran its ray screen flashed instantly to a temperature inconceivable, and, so long as the elements embedded in the infusible relux remained the metals they were, those tubes could not fail. But they were being lashed by the energy of half a sun. The tubes failed.
If infusible casings can be made, I think I am not overstating facts in saying that any temperature required can and will eventually be obtained with the greatest ease. What the limit is I have as yet not been able to discover.
