Microscope
166 (unassigned
maker; microscope universel; c. 1900)
Microscope 166 is a French
pocket microscope with variable magnification and can be dated to c. 1900.
The instrument is engraved with ‘MICROSCOPE UNIVERSEL À GROSSI VARIABLE,
BREVETÉ S.G.D.G.’ and can be used free-standing or hand-held (Figure 1A). The
magnification is varied by raising or lowering the draw tube. The cap on this
microscope houses a small round cork table onto which the specimen is laid or
pinned. The instrument collapses and folds into a small package and the
object holder serves as a lens cap. This kind of microscopes was apparently
made for decades and this instrument should be one
of the earlier versions. A new model was manufactured in the 1920s by the Manufacture
d'Armes et Cycles de St Etienne, containing a
more stable support (Figure 1B).
