This specimen is a monocular compound microscope made of brass.

The substage mirror is attached to the base of the hollow support pillar. Focus is by rack and pinion movement of the stage. A bull's-eye epi-illuminating glass is attached to body tube by a hinged arm. There is only one objective with this microscope. It has a single biconvex lens and is marked "11". The body tube optics consist of an eyepiece (with a single lens), a field lens, and the objective.

There is only one accessory: A stage-mounted sample forceps. Included are two prepared microscope slides: one of bird feathers and the other of fish scales.

This microscope is similar to microscope 7262 of the Museum Boerhaave dated 1800–1825.
