Hurlimann Sextant

Description
This sextant has a silvered scale that is graduated every 20 minutes from -5° to +175° and read by vernier with tangent screw and magnifier to 30 seconds of arc. The inscriptions read "Lorieux, A. Hurlimann succr à Paris" and "C. & G.S. 307." The U.S. Coast & Geodetic Survey acquired it in 1907 and transferred it to the Smithsonian in 1929.
A. Hurlimann was a mathematical instrument maker in Paris who took over Lorieux's shop in the early 1890s. He was succeeded by Ponthus & Therrode a few years later.
