Description

This compound microscope has a U-shaped brass base with a short rectangular pillar. Coarse focusing is done with a rack and pinion and fine focusing by a micrometer wheel on top of the limb. The two objectives, “3” and “7,” mount on a steel pivoting double nosepiece. The two lens Huygenian eyepieces are numbered “1” and “3.” The tube in which they fit has adjustable length and can be drawn out of the body tube, permitting compensation for the different focal lengths of objectives. The square stage has a steel top and brass bottom, with two spring clips for holding slides. The sub stage condenser is missing, but there is a sliding removable plate where it would be mounted. There is a substage plano-concave mirror, mounted on a swinging arm, which can also be slid up and down. The microscope is signed on the base: “E. Leitz  Wetzlar No 12523.”  Also engraved on the base is: “Educational Supply to Boston.” It comes with a mahogany carrying case.
