This is a compound monocular with coarse and fine focus, circular stage, inclination joint, support for sub-stage mirror, solid base, and wooden box with three eyepieces, four objectives, and a bullseye condenser with brass stand. The “NACHET / ET FILS / à Paris / rue St Séverin 17” inscription refers to a firm that began in business in 1840, and moved to this address in 1862. Weston College in Massachusetts gave this to the Smithsonian, but as that college was founded in the 1920s, the microscope was probably purchased for use at another Jesuit institution in the United States.
