Dear List members, Have we come to any agreement on what to call dials of the type suggested by John Singleton (page 51 of the BSS Bulletin for February 2000)? If not Singleton dials, then what?
For the benefit of those on this list who haven't seen the drawing, I attach a small GIF file (Singletn.GIF) of a scan. John's horizontal dial is drawn for latitude 51.5 N. The gnomon is a slender rod parallel with the earth's axis, penetrating the dial at the center of the concentric arcs. Best, Mac Oglesby Attachment converted: Macintosh HD:Singletn.GIF (GIFf/BOBO) (0000F9B3)
