Small Culpeper style microscope with rack and pinion focusing
This Culpeper type microscope is unsigned and dates from the early 19th century. Microscopes such as this are derived from the instruments of the earlier century made by Edmund Culpeper (1670-1737) and his contemporaries.
This microscope is stored in a pyramidal shaped case with lock and key and is mounted on a round brass base that supports three scrolled legs that in turn support the stage. The mirror is attached on a boss in the base. The circular stage has a central aperture for illumination by transmitted light. Three additional scrolled supports rise from the stage to carry the main tube. Focusing is achieved by rack and pinion moving the body tube. Among the surviving accessories are four numbered objectives, a stage forceps, a hand forceps, a sub-stage light cone, a Bonnani spring stage, an ivory talc box, a fish plate, and a collection of four ivory sliders each containing multiple specimens.
