Butterfield dial for latitudes 40°-55° North. Standard dial (see related terms) except for the following details: -

A single hour scale is depicted on a scroll, numbered IIII-XII, I-VIII. There is decoration around the compass and the gnomon hinge, and a centrally placed oval engraved with a foliate design. On the compass is an eight-point compass rose with the cardinal and quadrantal points named in French; the intermediate points being marked by single lines. The degree scale is depicted on a scroll clockwise around the North point, divided 30°-0°-30°. An engraved arrowhead points to magnetic North at 8° West of North. The latitude scale on the gnomon is adjustable for latitudes 40°-55° and is decorated with foliate engraving.

The compass base is engraved with acanthus leaves at the centre. The remainder of the compass and the reverse side of the dial-plate is filled with a table of latitudes of European cities and towns, and also Quebec which was a French colony until 1759. Despite the adjustable gnomon, this dial has only one degree scale (for which the latitude is not specified, but is measured as 49°). The signature, 'Haye AParis', is flamboyant and the decoration includes other foliate designs as well as the more normal acanthus.
