French botanical or entomological microscope,
unsigned, c. 1880
This is a French-made (presumably) botanical or entomological microscope. The maker is unknown. It focuses by movement of the stage utilizing a rack and pinion with the rack enclosed in the tube on which the stage slides. It is supplied with three screw-together objectives, which can be use individually or in combinations to vary the magnification. Also included is a brass live box, a glass stage insert, and five paper covered specimen slides by Bourgogne.
The focus mechanism, the shape of the knob, and the construction of the mirror are very similar to a group of other instruments in this collection suggesting that they all were made by the same firm.
