Inclining dial for latitudes 0°-60° north Long Caption: The hour-plate is hinged to the north side of the base-plate. Within the hour-circle, the brass gnomon is shaped and folds flat when not in use. The plate is cut away to reveal a silvered compass. It has a four-point rose and the cardinal and quadrantal points are designated by English initials. The degree scale for magnetic variation is divided 20˚-0˚-20˚, and is indicated by a brass slider, manipulated from the outside, which moves in a slit in the wall of the compass. The latitude arc, divided from tip 0˚-60˚, is hinged to the west side of the base-plate. The obverse side of the base-plate contains a table of latitudes of European towns and cites.
