This is a rare early polarization instrument. The essential components for polarization, particularly the polarization prism named after William Nicol, had been developed by Edinburgh mineralogists William Nicol (1770-1851) and David Brewster (1781-1861) in the early 19th century. In 1834, the Englishman William Henry Fox Talbot (1800-1877) proposed combining Nicol’s prisms with a microscope to observe thin sections of rock.

A rare rectangular graphometer by Gourdin, dated 1781

By Le Zograscope

Comments Off

On the back, it bears no trace for a ball joint or a support. It was therefore used directly on the planchette or perhaps attached to the board from one side empty. Thus, the two levels were Read More...
