This beautifully-crafted brass and wood microscope was designed by Dr. Lionel S. Beale and is signed: "C. COLLINS, Optician, 77 Gt. Titchfield St., LONDON". The microscope was photographed and described by Gerard Turner in his excellent volume Collecting Microscopes.

The microscope body tube is mounted horizontally, much like the design of the Bonanni horizontal microscope. Illumination is provided by an oil lamp at the left of the body tube, and the specimen is mounted onto a slide that is held by spring clips against the brass rim near the lamp. Focus is achieved by a rack and pinion mechanism that moves the inner body tube/ocular combination.
