This 8–inch theodolite was "especially adapted for triangulation." The "FAUTH & CO. WASHN D.C. No 1993" inscription indicates that it was made between 1887, when Saegmuller began putting serial numbers on Fauth instruments, and 1905, when Fauth & Co. went out of business. The edge of the horizontal circle is beveled, graduated, and read by opposite micrometer microscopes to single seconds. It belonged to the University of Missouri at Columbia. New, it cost $450.
