Microscope

Description
This compound monocular is a Spencer Model 18 with coarse and fine focus, triple nosepiece, square mechanical stage, inclination joint, sub-stage diaphragm, sub-stage mirror, horseshoe base, and wooden box with extra lenses. The inscription reads “SPENCER LENS CO. / BUFFALO, N.Y.” The 38521 serial number on the back of the base indicates a date of 1916. The Spencer Lens Co. termed this model “new” in 1917, noting that it was a “very high-grade” instrument “specially recommended for research work.” It was similar to the model 15, but with a plain, rectangular stage.
