Combined or impregnated with silicon. [Obsoles.] Siliciureted hydrogen. (Chem.) Hydrogen silicide. [Obs.]

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 ox…

ile, very malleable, and capable of a high degree of polish. It is found native, and also combined with sulphur, arsenic, antimony, chlorine, etc., in the minerals argentite, proustite, pyrargyrite, ceragyrite, etc. Silver is one of the "noble" metals, so-called, not being easily oxidized, and is used for coin, jewelry…

Single; not complex; not infolded or entangled; uncombined; not compounded; not blended with something else; not complicated; as, a simple substance; a simple idea; a simple sound; a simple machine; a simple problem; simple tasks.

Not doubled, twisted together, or combined with others; as, a single thread; a single strand of a rope.

A somewhat similar expression of countenance, indicative of satisfaction combined with malevolent feelings, as contempt, scorn, etc; as, a scornful smile.

A common metallic element of the alkali group, in nature always occuring combined, as in common salt, in albite, etc. It is isolated as a soft, waxy, white, unstable metal, so readily oxidized that it combines violently with water, and to be preserved must be kept under petroleum or some similar liquid. Sodium is used…

al instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimpose…

Combined or impregnated with antimony (stibium). Stibiated tartar. See Tartar emetic, under Tartar.

A metallic element of the calcium group, always naturally occurring combined, as in the minerals strontianite, celestite, etc. It is isolated as a yellowish metal, somewhat malleable but harder than calcium. It is chiefly employed (as in the nitrate) to color pyrotechnic flames red. Symbol Sr. Atomic weight 87.3. A rad…

twist, material for a gun barrel, made of a spirally welded ribbon of steel and stub iron combined.

as, stylographic ink. Stylographic pen, a pen with a conical point like that of a style, combined with a reservoir for supplying it with ink. -- Stylographic pencil, a pencil used in stylography.

A nonmetallic element occurring naturally in large quantities, either combined as in the sulphides (as pyrites) and sulphates (as gypsum), or native in volcanic regions, in vast beds mixed with gypsum and various earthy materials, from which it is melted out. Symbol S. Atomic weight 32. The specific gravity of ordinary…

s of combining or impregnating with sulphur or its compounds; also, the state of being so combined or impregnated.

Combined or impregnated with sulphur; sulphurized. [Written also sulphuretted.] Sulphureted hydrogen. (Chem.) See Hydrogen sulphide, under Hydrogen.

ly liquid, H2SO4, colorless when pure, but usually yellowish or brownish, produced by the combined action of sulphur dioxide, oxygen (from the air), steam, and nitric fumes. It attacks and dissolves many metals and other intractable substances, sets free most acids from their salts, and is used in the manufacture of hy…

To combine or impregnate with sulphur or any of its compounds; as, to sulphurize caoutchouc in vulcanizing.

To impregnate or combine with an excess of sulphur.

To combine with oxygen so as to form a suroxide or peroxide. [Obs.]

A gradual increase and decrease of the volume of sound; the crescendo and diminuendo combined; -- generally indicated by the sign.
