This is a compound monocular with coarse and fine focus, inclination joint, circular stage, and circular base with three ball feet. The “E. H. GRIFFITH, FAIRPORT N.Y. / PAT. DEC. 14, 86 / 866” inscription on the stand refers to Ezra Hollace Griffith (1838-1894), a travelling salesman and enthusiastic microscopist. Griffith described this form, termed the Griffith Club Microscope, as a “full-sized, first-class” instrument that was “free from tremor, unique in design, and beautiful in appearance.” Bausch & Lomb made the objective for this example, and may also have made the stand as well.

The stage has been modified. The raised ring held by screws is a later modification. The original stage would have been a flat black glass disk.
