Silicon :: Silicon (n.) A nonmetalic element analogous to carbon. It always occurs combined in nature, and is artificially obtained in the free state, usually as a dark brown amorphous powder, or as a dark crystalline substance with a meetallic luster. Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust. Silicon is characteristically the element of the mineral kingdom, as carbon is of the organic world. Symbol Si. A

Bisilicate :: Bisilicate (n.) A salt of metasilicic acid; -- so called because the ratio of the oxygen of the silica to the oxygen of the base is as two to one. The bisilicates include many of the most common and important minerals.
Venous :: Venous (a.) Contained in the veins, or having the same qualities as if contained in the veins, that is, having a dark bluish color and containing an insufficient amount of oxygen so as no longer to be fit for oxygenating the tissues; -- said of the blood, and opposed to arterial..
