This makes up one-quarter of the crust, leaving only one-quarter to be accounted for. Silicon mixed with oxygen makes silica or quartz. There are few rocks which have not a large amount of quartz in them. Common flint, sandstones, and the sand of our shores, are made of quartz, and therefore belong to the first class of Silicious or Flint Rocks. Granites and lavas are about one-half quartz.
The process consists in forcing through molten cast iron, held in a vessel called a converter, a stream of cold air under pressure. The combination of the oxygen in the air with the silicon and carbon in the metal raises the temperature of the latter in a spectacular way and after "blowing" for a certain period, eliminates the carbon from the metal.
Magnesium is found principally as phosphate in the bones. It is present both in animal and vegetable foods. Its function in the body is not well understood, but it appears to assist the phosphorus. Silicon is found in traces in the human body.
The modern chemist makes no claim for his elements except that they have thus far resisted all human efforts to dissociate them; it would be nothing strange if some of them, when subjected to the crucible of the sun, which is seen to vaporize iron, nickel, silicon, should fail to withstand the test.
This gas makes up nearly one-quarter by weight of the atmosphere round the whole earth. The same gas plays an important part in the ocean; for more than three-quarters of water is oxygen. It plays also an important part in rocks; for about half the material of the entire earth's crust is oxygen. Another chief material in rocks is silicon.
A device for sealing together the inside part and bulb of an incandescent lamp mechanically. Regulators for dynamos and motors. Three devices for utilizing vibrations beyond the ultra violet. A great variety of methods for coating incandescent lamp filaments with silicon, titanium, chromium, osmium, boron, etc. Several methods of making porous filaments.
But his experiments have been carefully repeated by qualified persons, and they have completely proved his ignorance: his rhodium is iron, and his silicon an impure incombustible coal. My dear Sir,
He came back. As he came, he wound something into a little coil. It was the silicon bronze mainspring of his non-magnetic watch. He held it for her to see and put it in his pocket. "I know what the terror beam is for what good it'll do!" he said bitterly. "It's a beam of radiation on the order of radar, and for that matter X-rays and everything else.

"The base is comfortable, and we only work a two-hour shift out of each ten. We've had a plague of silly dillies recently. They got into one man's suit while we were working, but mostly they're just a nuisance." Rip had heard of the creatures. They were like Earth armadillos, except that they were silicon animals and not carbon like those of Earth.
