Description
Throughout the 18th century, microscopy remained essentially an amateur activity, the province of educated naturalists and gentlemen with time to explore the mysteries of science.

Instrument makers responded to the nature of the demand for their products with ingenious developments in design. This instrument is an example of a delicately made pocket microscope which could be dismantled and fitted into an attractive miniature case.
