Magnetic dial for latitude 52â”œÃ—_ north. Round brass sundial in a case with a suspension ring. The dial is set on a printed magnetic compass card, which is free to rotate with the movement of a bar magnet on the underside so that it is correctly oriented. The dial-plate has 32 compass points marked around the edge, 15 by English initials and north by a fleur-de-lys. Within this is an hour ring divided clockwise 5 am-7 pm with a sunface at the south point. A simple brass gnomon is set on the dial-plate and a glass plate is set over all and held in place by the metal of the case.
