Microscope

Description
This is a compound binocular with inter-ocular adjustment, coarse and fine focus, trunnion, circular stage, sub-stage condenser and diaphragm, Lister limb with sub-stage mirror, and Y-shaped base. Accessories include a bullseye condenser with stand, glass stage, forceps, slides, objectives signed Tolles, R. & J. Beck, and W. Wales, and a wooden case. The “BAKER / 244 High Holborn / London” inscription refers to Charles Baker, a prolific instrument maker who began in business in 1851.
Francis Herbert Wenham (b. 1824), an English engineer and active microscopist, designed a four-sided prism suitable for binocular microscopes around 1860. Several London opticians were offering instruments of this sort by 1861, and some showed examples at the London Exhibition of 1862. Baker began advertising binocular microscopes in 1867; the Royal Microscopical Society bought an example the following year.
