Scope and Contents
Arcs of black water-proof material were used to register the daily path and burning power of the sun and are pasted on sheets of heavy cartridge paper joined together to form a continuous strip.
Loosely inserted at the back of the folder is a sheet of linen on which several printed diagrams are mounted illustrating the sun`s burning power ascertained from Campbell`s Registering Sun-Dial in 1855-1856.
Later notes of Campbell dated 4 July 1881 appear on the first board with a photograph of a modification of his sun-dial at Greenwich Observatory.
