content: This Continental model A is a simple and inexpensive compound monocular with rack-and-pinion, curved arm, square stage, and sub-stage mirror. The inscription on the horseshoe base reads “Bausch & Lomb Optical Co. / ROCHESTER, N.Y.” The 41564 serial number suggests a date of 1903. Bausch & Lomb introduced the form in the 1890s, noting that it could be used for such practical purposes as examining starches, fabrics, and foods thought to be rotten or adulterated.
