     4. An instrument for measuring altitudes, variously
        constructed and mounted for different specific uses in
        astronomy, surveying, gunnery, etc., consisting commonly
        of a graduated arc of 90[deg], with an index or vernier,
        and either plain or telescopic sights, and usually having
        a plumb line or spirit level for fixing the vertical or
        horizontal direction.

     Gunner's quadrant, an instrument consisting of a graduated
        limb, with a plumb line or spirit level, and an arm by
        which it is applied to a cannon or mortar in adjusting it
        to the elevation required for attaining the desired range.
        
  
     Gunter's quadrant. See Gunter's quadrant, in the

     Hadley's quadrant, a hand instrument used chiefly at sea to
        measure the altitude of the sun or other celestial body in
        ascertaining the vessel's position. It consists of a frame
        in the form of an octant having a graduated scale upon its
        arc, and an index arm, or alidade pivoted at its apex.
        Mirrors, called the index glass and the horizon glass, are
        fixed one upon the index arm and the other upon one side
        of the frame, respectively. When the instrument is held
        upright, the index arm may be swung so that the index
        glass will reflect an image of the sun upon the horizon
        glass, and when the reflected image of the sun coincides,
        to the observer's eye, with the horizon as seen directly
        through an opening at the side of the horizon glass, the
        index shows the sun's altitude upon the scale; -- more
        properly, but less commonly, called an octant.
  
     Quadrant of altitude, an appendage of the artificial globe,
        consisting of a slip of brass of the length of a quadrant
        of one of the great circles of the globe, and graduated.
        It may be fitted to the meridian, and being movable round
        to all points of the horizon, serves as a scale in
        measuring altitudes, azimuths, etc.
        [1913 Webster]
