William Withering (1741-1799) designed a number of simple microscopes for use in the field, a first one was described in 1776, this foldable one with one single pillar dates from circa 1800.
A wooden box with a hinged lid, the inside of the box is lined with green velvet, the lid with the original label describing the use of the instrument. Opening the box raises the pillar carrying the round stage and the lens holder. The lens is double convex. There are a pin, a pair of tweezers and a little knife in the box.
