Such a vacuum also reduced wear on the graphite points between which the luminous arc expanded. This was an important savings for Captain Nemo, who couldn't easily renew them. But under these conditions, wear and tear were almost nonexistent. When the Nautilus was ready to resume its underwater travels, I went below again to the lounge.
Once more in the hansom, she ordered the man to drive her to Charing Cross, and when she was ten minutes away from Rupert Square she changed her direction and desired him to take her to the office of the Evening Graphite, where she knew Mr. Stoneham would be busy with his leading article, and probably impatiently awaiting further details of the conspiracy he was to lay open before the public.
He unlocked this, which was guarded by a combination lock, like that of a bank vault, and waited for them to enter; then closed it after them, and made quite sure the metal door was fast. A peculiar, pungent smell greeted the partners' nostrils as they glanced about the inner laboratory. At one side an electric furnace was glowing with graphite crucibles subjected to terrific heat.
Silica, and graphite when it is present, need not be removed by filtration, if it is not intended to estimate them, or there be no fear that the graphite is accompanied by any humous substance, or that any oily, viscous compound has been deposited on the sides of the beaker. In the last mentioned case the solution should be transferred into another beaker, and filtered, if graphite be present.
Each cell of all the plants of this genus produces a large number of mobile cells zoospores. M. Berthelot, in the Journal de Pharmacie et de Chimie for March, states that from peculiar physical relations he is led to suspect that the true element carbon is unknown, and that diamond and graphite are substances of a different order.
In this both modern Science and the Yogi Teachings agree fully. In investigating protoplasm we are made to realize the wonderful qualities of its principal constituent Carbon. Carbon is the wonder worker of the elements. Manifesting in various forms, as the diamond, graphite, coal, protoplasm is it not entitled to respect?
T. Sterry Hunt asserted "that the presence of iron ores, not less than that of graphite, points to the existence of organic life even during the Laurentian or so-called Azoic period." In 1861 he went farther and stated his belief in "the existence of an abundant vegetation during the Laurentian period."
I then transferred the weighed sample to the crucible, the melted potash in which readily wetted the graphite rock. The mass was then gently heated, and occasionally stirred with a piece of silver wire.
Others were smearing the last heavy dabs of tallow, lard oil, and soft soap on the ways, and graphite where the ways stretched two hundred feet or so out into the water, for the ship was to travel some hundreds of feet on the land and in the water, and perhaps an equal distance out beyond the end of the ways. Late comers still crowded in. Men now reported that everything was ready.
The wax mould is laid face upward on the floor of an inclosed box, and a torrent of finely pulverized graphite suspended in water is poured upon it by means of a rotary pump, a hose, and a distributing nozzle which dashes the liquid equally over the whole surface of the mould. Superfluous graphite is then removed by copious washing, an extremely fine film of graphite adhering to the wax.
