Microscope

Description
This is a small compound monocular with rack-and-pinion focus, rectangular stage with clips, and separate condensing lens in brass frame. It could be hand-held or stood upright. It was collected by Richard Halsted Ward (1837-1917), an American medical microscopist, or his son, Henry B. Ward, a pioneering parasitologist. The “MURRAY & HEATH / LONDON” inscription refers to a firm that began in business in 1856, and that showed various instruments at the International Exhibition in London in 1862.
