Philadelphia Pennsylvania USA Vertical Dial 149
On wall of the passage from hallway to kitchen inside the house, just for exhibition. 9.5 x 19 inches, rough wood painted in black, roman numerals from 8 am to 5 pm on 1.5 inches wide frame, it was for hanging on a declining wall. Black iron gnomon rod, 1 foot in length, is supported with iron vine which is fixed to a point on the dial plate about 1.5 inches from the noon line. Unfortunately, the gnomon seems twisted, so that it points down over the noon line, like those for dials facing true south. Admission fee: $5.00 for guided tour. No photo allowed inside.
 
 
Philadelphia Pennsylvania USA Horizontal 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.
