Dissecting microscope with a single lens, square stage, sub-stage mirror, steel pillar, square base made of black iron, arm rests, and wooden case. John J. Bausch obtained a patent on the form in 1880. Bausch & Lomb touted it as “the most compact, portable and efficient Dissecting Microscope on the market." The “OGDEN / BOSTON” inscription on this example refers to a microscopist and instrument dealer, as does the paper label reading “From / JOHN T. OGDEN / 168 Tremont St. / Boston.”
This may have been used by Richard Rathbun (1852-1918) or by his sister, Mary Jane Rathbun (1860-1940), both of whom worked at the Smithsonian.
