volgerite

[After G. H. O. Volger; suff. -ite ( Min.).] Min .: An oxide of antimoy occurring ma ive or pulverulent. Color, white. Composition: Oxygen, 19-3: antimony, 58.9; water, 21.8=100, with the formula SbO5+5HO. *vol-it-a-ble, a . [Eng. vol at ( ile ); -able .] Capable of being volatilized. "This vol i table spirit is soon spent." -Hopkins : Sermons; John iii. 5. *võl-i-ta-tion, s. [Lat. volito , freq. from volo to fly.] The act or state of flying; flight. "Birds or flying animals are.. only prone in the act of volitation."-Browne: Vulgar Errors, bk. iv., ch. i. chin, bench; go, gem; thin, this; Palæobot .: A genus of Equiseta cee, from the Coal Measures. They have verticillate leaves, and Asterophyllites in fructification. võlks-raad (folks'-rat), s. [South African Dutch.] The legislative body of the Transvaal or South African Republic. "The Transvaal has a constitution. By this constitution the volksraad is declared to be the supreme power in the State."-London Truth , April 10, 1897. võl-ley, *võl-lý, s . [Fr. volée a flight, a volley, a flight of birds, from Lat. volata , fem. of volatus , pa. par. of volo =to fly; Ital. volata =a flight, a volley.] 1. A flight of mi iles, as of shot, arrows, .; a simultaneous discharge of a number of mi iles, as small-arms. "Welcomed one another with a thundering volley of shot."-Hackluyt: Voyages , iii. 82. 2. A noisy or explosive burst or emi ion of many things at once. 3. ( In tennis and other ball games): A return of the ball before it touches the ground. A return immediately after the ball has touched the ground is called a Half-volley. (1) Half - volley : [VOLLEY, 8., 3.] *(2) On the volley : At random. võl-leỹ, v . t . & i. [VOLLEY, 8.] A. Trans.: To discharge in, or as in a volley. "He strove, with volleyed threat and ban." *B. Intransitive : Scott : Rokeby , v. 33. 1. To discharge at once, or in a volley. "Cannon to right of them Volley'd and thunder'd." Tennyson: Charge of the Light Brigade . 2. To sound like a volley of artillery. "And there the volleying thunders pour." Byron: Siege of Corinth, ii. larger, and the other by the hinder feet smaller the shoulders bearing outward, and the croup approaching toward the center. ( Farrier's Dict .) [DEMIVOLT.] 2. Fencing : A sudden movement or leap to avoid a thrust. volt (2), subst. [Named in honor of A le andro Volta.] [VOLTAIC.] Elect.: The unit which expre es difference of potential. An electrical current is in many respects analogous to a flow of water. The fundamental unit (UNIT, 4.) is one of mere quantity, the Coulomb, and merely expre es sufficient current to do a certain amount of work. But the same quantity of water would flow through a large pipe at one inch per second, and through one-half the diameter at four inches per second. Hence we get the unit expre ing quantity per second (the ampère); and thirdly, as a greater pre ure or force is required to drive water at a given rate per second through a small pipe, or greater resistance, so as to maintain a given quantity per second, in electrical currents we have this force or pre ure, considered as the difference of potential or electrical pre ure at the two ends of the circuit of wire. The resistance of a wire to the pa age of a circuit is measured in ohms (units), and a volt is the differ ence of potential required to drive an effective current of one ampère through a wire interposing the resistance of one ohm.
