BOOKPLATES OF GOVERNMENT LABORATORIES AND RESEARCH INSTITUTES

 

The Billings Microscope Collection is housed in Washington D.C. at the Armed Forces Institute of Pathology, which was founded as the Army Medical Museum in 1862.  The bookplate (Figures 19, 20) of the Armed Forces Institute of Pathology Library, now quite scarce, depicts a microscope with aperture wheel and bulls-eye lens.  Before the adjustable iris diaphragm, one rotated a wheel that had holes of different diameter; changes in the numerical aperture of the condenser to correspond to objective numerical aperture were made by changing hole size – all of which could be viewed at the objective back focal plane.  There is a sliding tube coarse focus, and pillar-mounted fine adjustment.
