Compound Microscope in Case, by Andrew Ross, London, c. 1835

A turned pillar stands on a flat base with three fold-out feet. The stage is attached to the top of the pillar by a compass joint. The stage plate rotates and a removable stage plate with a bracket which supports specimens is held on the plate by spring clips. The cylindrical limb passes though the stage. Two steadying struts attach the stage to the lower end of the limb where a socket holds the plano-concave mirror. Two milled heads at the rear of the limb raise a triangular sectioned bar that holds a vertical arm supporting the body tube. The microscope is housed in a hinged varnished wooden case with metal borders and handles on either side. The wooden case also contains five eyepieces, two objectives in cans, a stage bracket on pins, a milled head screw, and a slide.
