This is a stereoscopic instrument with coarse and fine focus, square stage, folding wooden ramps that clip to the stage, sub-stage mirror, and wooden box with extra lenses. The inscription reads “CARL ZEISS / JENA” and “GERMANY.” There may be a 1741319 serial number.
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. The firm introduced this model XA stand in the early 1930s.
