This is a nickel-plated dissecting instrument with sub-stage mirror, heavy black base, removable hand rests, and wooden box. The inscription reads “CARL ZEISS / JENA.” The Zeiss firm began in 1846 and produced their 1000th microscope in 1866. The “8947” serial number on this example suggests a date of around 1875.
This belonged to Eugene Amandus Schwarz (1844-1928), a German-American entomologist who arrived in the United States in 1876, worked for the U.S. Department of Agriculture and served as honorary curator at the Smithsonian’s National Museum of Natural History.
