Equinoctial dial Long Caption: Universal equinoctial dial for all latitudes. The hour-circle is silvered and hinged to the north side of the dial-plate. A brass strut attached to the hour-circle supports a brass rod gnomon. The latitude arc, divided from the tip [0˚]-[90˚], is hinged to the east side of the dial-plate. Set into the base-plate, the compass is made of silvered brass. It features a highly decorated four-point rose with the cardinal and quadrantal points named by English initials. It has a thick needle (slightly rusty) surmounted by a brass cylindrical pivot and has an arm to lift it and lock it in position against the glass. There are also two brass bubble levels set into it. A glass plate covers all.
