Circular inclining dial for latitudes 0°-60° North. The hour-circle is hinged to the North side of the base-plate and numbered IIII-XII, I-VIII. Decorated circle arcs support the pierced brass gnomon, which folds flat when not in use. The latitude arc is hinged to the East side of the dial-plate, engraved on the outside only and divided from the tip 0°-60°. The compass is set into the base-plate and displays a highly decorated four-point rose whose cardinal and quadrantal points are named by English initials. The needle, with a black bar to mark North, is surmounted by a brass cylindrical pivot and has an arm to lift and lock it in position against the glass which is operated from outside the compass. Two brass spirit levels are set into the compass and a glass plate covers all.

This dial, signed 'Bate, London,' on the hour-circle, was made by one of the Bate family who had a workshop in the Poultry, London. It is very likely to have been Robert Brettell Bate, who is known to have made a full range of instruments. The style of engraving is similar to some of the English universal equinoctial ring dials of the later 18th century.
