c. 1720-30

A brass screw-barrel microscope with an ivory handle.

Brass barrel with its condenser lens and spring stage retainer.

Four numbered objectives are present; opaque specimen holder with ebony disc, a brass slide with corresponding glass, objective holder with dark brown horn-mounted lens for opaque specimens.

Four ivory sliders (numb. 1-4) in original cardboard case covered by pink and gold paper (for an identical paper see: https://blogs.library.duke.edu/rubenstein/2014/12/16/glass-eyeballs-amputating-saws-enema-syringes-oh/ )

The wooden case is covered on all sides by black fishskin (slightly unglued but firm), green velvet lined inside. It has originally no hooks, but a central brass button, as for the typical early Culpeper’s screw barrels.

Edmund Culpeper (c.1660-1737) was an engraver and mathematical instrument maker in Moorfields, London. In the early years of the 18th century he extended his range of instruments by making screw-barrel microscopes.

James Wilson published the first description with the design of this microscope in the Philosophical Transactions of the Royal Society in 1702.
