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.
