This is a convertible instrument that can be used as either a simple microscope or a compound monocular. It has rack and pinion, stage, and sub-stage mirror, and it fits into and stands on a small wooden box. The “Carey, LONDON” inscription refers to a large, long-lived, and prolific family of instruments makers known variously as Cary and Carey. Charles Gould, an employee of William Cary, described the form in 1827, and probably devised it as well.
