surveying instrument consisting of the upper movable part of a theodolite including the telescope and its attachments

The portion of a graduated instrument, as a quadrant or astrolabe, carrying the sights or telescope, and showing the degrees cut off on the arc of the instrument surveying instrument used with a plane table for drawing lines of sight on a distant object and for measuring angles surveying instrument consisting of the upper movable part of a theodolite including the telescope and its attachments
