Microscope 154 (unassigned maker; pocket microscope; late 19^th to early 20^th centuries)

Microscope 154 is a simple pocket microscope from c. 1900 to early 20^th centuries. This microscope has a single simple lens with a magnification of 50x and a recess into which a slide could be fitted for examination. The two protruding bars attach to a spring within the instrument that hold the slide in place once it is inserted. The eyepiece of the microscope can then be moved in and out to focus the image of the object of interest. Microscopes like this example became popular in the late 19th and early 20th centuries and were manufactured mainly in France and Germany. Examples featured in the catalogues of Ferdinand Ernecke and Geissler are shown below (Figure 1).
