Description

SET OF TWENTY LARGE WOOD SLIDERS WITH PREPARED SPECIMENS, French, c. early 19th century. Each slider is made of sturdy tan wood 4-7/8″ (12 cm ) long, with beveled ends (for insertion in a microscope stage carrier), and with two prepared specimens mounted between glass disks and held in place by brass spring rings. Each specimen is identified in French, directly on the slider in ink writing. Condition is fine throughout except most showing drying and crazing of the mounting cement. The specimens however, which are of various natural history subjects, are still quite visible, and fascinating viewed through a microscope. The set is contained in an associated mahogany box.

These sliders are transitional between the ivory mounts with multiple specimens set between mica disks, which were made throughout the 18th century, and the all glass slides with usually single specimens set under cover glass which became standard by the 1840¹s.
