Mount Laguna California USA Equatorial Dial Dial 170
The odd bowl-shape of this equatorial dial designed and built by C.T. and W.M Thwaites shows a reversed engraved map of the world. A horizontal bar across the bowl has a small metal nib which points out the time of the day (top and bottom for standard and daylight times) and also indicates the spot on the world where the Sun is currently directly overhead. On full Moon nights, this dial has been used to effectively tell time and show the position of the Moon over the Earth as well.

Philadelphia Pennsylvania USA Horizontal Dial Dial 148
Horizontal dial approximately one foot diameter mounted on old stone atop a 3 foot stone pedestal. It is sitting against north wall of the garden and not aligned in proper direction. Plaque at the base states "This sundial stood for over a century in the gardens of Dorchester House, Park Lane, London, England. Presented by The Soroptomist Club of Philadelphia, December 23, 1935". This may be true for the dial plate because the hour angles indicate a latitude of 51°, the London latitude. It may not be true for the gnomon, whose style angle is 40°, the Philadelphia latitude. Access by taking guided tour, $5; then ask for garden.
