Compound microscope built by George Adams Junior, who described it as an improved compound microscope. A pillar mounted on a tripod bears a ball-and-socket joint to which a rod is fitted. The rod carries the illumination mirror, the stage, and the body-tube. The tube contains an eyepiece with two double-convex converging lenses and a field lens. The box for the microscope contains eight objectives and several accessories for preparing specimens. Provenance: Lorraine collections.
