The probability of puncture or discomfort from the points is almost negligible. When the needle on the instrument panel flickered, he got to his feet and began moving. He was almost certain that he had not been detected. Walking was out of the question. This was a silicate-alumina rock, not a nickel-iron one.
In the year last named Edison first brought out his new form of nickel-iron cell with alkaline electrolyte, as we have related in the preceding narrative.
He finally thought that a good storage battery was a great requisite, and decided to try and devise a new type, for he declared emphatically he would make no battery requiring sulphuric acid. After a little thought he conceived the nickel-iron idea, and started to work at once with characteristic energy.
Maybe they thought that they would be located and picked up the gang that had robbed and dumped them had found them easily enough. But there, again, was a paradox of enormity. Bands might wait for suckers somewhere beyond Mars. Elsewhere, there could be nobody for millions of miles. They saw their first asteroid a pitted, mesoderm fragment of nickel-iron from middle-deep in the blasted planet.
And again, on November 27, 1885, while the skirts of the Andromede-tempest were trailing over Mexico, "a ball of fire" was precipitated from the sky at Mazapil, within view of a ranchman. Scientific examination proved it to be a "siderite," or mass of "nickel-iron"; its weight exceeded eight pounds, and it contained many nodules of graphite.
It was one of these masses, which consist of nickel-iron containing a small quantity of platinum, and of which in all some ten tons have been recovered for sale to the various collectors throughout the world, that as before mentioned destroyed the grinding-tool at Philadelphia through the cutting power of its embedded diamonds.
Mars became an agate bead, then a hazy sphere with those swirled, almost fluid markings, where the spores of a perhaps sentient vegetable life followed the paths of thin winds, blowing equatorward from the polar caps of hoarfrost. The three stellene rings bumped lightly on the ten mile chunk of captured asteroidal rock and nickel-iron that was Phobos, Mars' nearer moon. Gravitation was almost nil.
This 'nickel-iron, as it is commonly called, is usually crystalline in texture, and when it is cut, polished, and 'etched' a beautiful net-work of lines is brought out, indicating plates which lie in positions determined by the crystalline character of the mass. This net-work of lines constitutes what are called the Widmannstattian figures, from the name of their discoverer.
