What's the difference between circumferentor and horizontal?
Circumferentor
Definition:
(n.) A surveying instrument, for taking horizontal angles and bearings; a surveyor's compass. It consists of a compass whose needle plays over a circle graduated to 360ยก, and of a horizontal brass bar at the ends of which are standards with narrow slits for sighting, supported on a tripod by a ball and socket joint.
(n.) A graduated wheel for measuring tires; a tire circle.
Example Sentences:
Horizontal
Definition:
(a.) Pertaining to, or near, the horizon.
(a.) Parallel to the horizon; on a level; as, a horizontalline or surface.
(a.) Measured or contained in a plane of the horizon; as, horizontal distance.
