Fauth Geodetic Transit

This instrument, which belonged to Columbia University, was made after 1874 when Fauth & Co. began in business, and before 1887, when Saegmuller began putting serial numbers on Fauth instruments. Fauth termed it a "Combined Transit and Zenith Instrument, as devised by Prof. G. Davidson, U. S. C. S." The frame consists of two parts—the upper one, with the uprights, can revolve upon the lower. New, it cost $990. This example differs from the instrument shown in the Fauth Catalogue. Here the small vertical circles are placed at one end of the horizontal axis. The signature reads "Fauth & Co. Washn D.C."
