An instrument for directing or ascertaining the course of ships at sea, consisting of a circular box, containing a paper card marked with the thirty two points of direction, fixed on a magnetic needle, that always points to the north, the variation excepted. The needle with the card turns on a pin in the center of the box. In the center of the needle is fixed a brass conical socket or cap, by which the card hanging on the pin turns freely round the center. The box is covered with glass, to prevent the motion of the card from being disturbed by the wind.

There are also compasses of three legs or triangular compasses, cylindrical and spherical compasses with four branches, and various other kinds.

An instrument used in surveying land, constructed in the main like the mariners compass; but with this difference, that the needle is not fitted into the card, moving with it, but plays alone; the card being drawn on the bottom of the box, and a circle divided into 360 degrees on the limb.
