Microscope

Description
This is a stereoscopic instrument with coarse and fine focus, square stage, sub-stage diaphragm, sub-stage mirror, and wooden box with extra lenses. The inscriptions read “CARL ZEISS / JENA” and “GERMANY” and “215763.” A property tag reads “U.S.N.M. / Division of Marine Invertebrates / SMITHSONIAN INSTITUTION / 31969.”
Zeiss began marketing stereoscopic microscopes in 1897, noting that the idea had originated with Horatio Saltstall Greenough (1845-1916), an American zoologist and, incidentally, son of the sculptor, Horatio Greenough. Zeiss introduced this model XA stand in the early 1930s.
