Microscope

Description
This is a brass screw-barrel microscope—of the sort that the English optician, James Wilson, introduced to the Royal Society in 1702—with a detachable wooden handle; three condensing lenses, each in a brass holder; a brass bar holding six objectives; nine ivory sliders; and a forceps. A second brass tube with a large and almost flat condensing lens could be used to connect the microscope with a (missing) window plate and mirror, so that this could be used as a solar microscope.
Colby College was established in 1813, and may have acquired this microscope at that time.
