content: Bausch & Lomb introduced their Large Continental in 1891, noting that “no efforts have been spared to make the stand the most complete and fitted with all modern improvements and appliances.” This example is a compound monocular with coarse and fine focus, triple nosepiece (but only one objective), inclination joint with clamp (the handle is made of celluloid), large circular stage, sub-stage Abbe condenser and iris diaphragm, and support for sub-stage mirror (the mirror is missing). The instrument is brass, the draw tube is nickel plated, and the stage is covered with vulcanized rubber. The inscription on the horseshoe base reads “Bausch & Lomb Optical Co. / ROCHESTER, N.Y. & NEW YORK CITY / 14317.” The serial number indicates a date around 1894.
