Blunt Sextant

Description
Theodorus Bailey Myers Mason (1848-1899), a career naval officer, probably acquired this sextant in 1865 when he graduated from the Naval Academy at Newport, R.I. It has a silvered scale that is graduated every 10 minutes from -5° to +155° and read by vernier with tangent screw and swinging magnifier to 10 seconds. The inscription reads "E. & G. W. Blunt, New York." Mason's sister Cassie (Mrs. Julian) James, a Washington socialite, donated this and other family items to the Smithsonian.
