Compound, Simple and Magic Lantern Microscope Set by George Adams Jr., ca.1790.
This is a rare late 18th century mahogany wood box, with compound and simple microscope with many accessories, and a magic lantern (lanterna magica) microscope with objectives and specimens, designed (as we know from the Museo Galileo example) to be combined with another case including the famous Adams lucernal microscope. These optical compendia are unsigned, but were certainly made by George Adams Junior. Ferdinand III Grand Duke of Tuscany (1769-1824), Holy Roman Emperor, King of Hungary, and Bohemia from 1790 to 1792, and Archduke of Austria and Grand Duke of Tuscany from 1765 to 1790, personally donated the similar set to the Museo di Fisica e Storia Naturale (AKA Museo Galileo) of Florence in 1791.
The compound microscope is mounted on a square-sectioned pillar fitted with a flat tripod. The illumination mirror is hinged near the base and above it travels the stage. The body-tube is attached to the top of pillar and its eyepiece is fitted with two converging lenses and a field lens. The instrument, which fits into the same box as the lucernal microscope, also has an objective.
