This is a dissecting microscope with nickel-plated tube, two lenses, square glass stage, sub-stage mirror, black horseshoe base, and wooden case. The inscription reads “Bausch & Lomb Optical Co.” and the 61518 serial number suggests a date of around 1906. According to trade literature, the form (Stand Y) was the largest and most complete of the Bausch & Lomb dissecting microscopes, and was first constructed according to the specifications of Paul Meyer, a German scientist who was a leader of the Naples Zoological Station in the last quarter of the nineteenth century.
