John Yarwell Compound Monocular Microscope

The Marshall-style compound monocular microscope featured below was probably built by John Yarwell during the late 1600s and has been redrawn from photographs of the original microscope, which is featured in Gerard Turner's excellent book Collecting Microscopes, a volume in Christie's International Collectors Series of books on antiques.

The wooden base and lens mounts are made from turned walnut and were varnished to provide protection and a high degree of luster. A brass pillar is fastened to one edge of the base by means of a wing nut that also secures the stage. The microscope body has a threaded brass nosepiece, which contains the objective lens, and is also screwed into an adjustable bracket that can be slid up and down on the pillar by means of a wingnut. Coarse focus is achieved by sliding the nosepiece bracket on the pillar, while fine focus occurs when the microscope body is turned in the nosepiece bracket. The body is fashioned from pasteboard and adorned in tooled leather.
