J. Swift & Son, Portable Clinical & Field Microscope, 1900

 

James Swift and Son designed this collapsing microscope with its solid leather case for the military doctors and traveling scientists at the very beginning of the 20th century, undoubtedly under the influence of Charles Baker's "The Diagnostic No. 1" (YG-005 in this collection). At the same time the same firm designed the more robust "Discovery Microscope" (YG-049) for the Discovery Antarctic Expedition. But the microscope seen here was made to be highly compact and portable without compromising on quality. As the sales advertisement by J. Swift & Son, ca. 1900, states: “This microscope was originally designed to meet the requirements of the Bacteriologist who needed an instrument of utmost portability. It is particularly serviceable to Microscopical and Natural History Societies, as its extreme portability, combined with great steadiness and efficiency for high power investigations, recommends it strongly. These instruments are in very general use in India and Africa amongst those working on Malaria, Sleeping Sickness, etc., and have been supplied in great numbers to the Army Veterinary Departments, the Crown Agents for the Colonies, the United States Government, etc.”.
