GLOBE, a sphere, round solid body, which may be conceived to be generated by the revolution of a semicircle about its diameter. An artificial globe in geog- raphy and astronomy, is a globe of metal, plaster, paper, pasteboard, etc., on the surface of which is drawn a map, or representation of either the earth or the heavens, with the several circles which are conceived upon them, the for- mer being called the terrestrial globe, and the latter the celestial globe. In the terrestrial globe the wire on which it turns represents the earth's axis, the extremities of it representing the poles. The brazen meridian is a vertical circle in which the artificial globe turns, divided into 360 degrees, each degree being divided into minutes and seconds. The brass meridian receives the ends of the axis on which the globe revolves. At right angles to this, and consequently horizontal, is a broad ring of wood or brass representing the horizon; that is, the true horizon of the earth which lies in a plane containing the earth's center. GLOBE FISHES, the family Gymno' dontidfe, of which the chief genera are Diodon and Tetraodon.
