The Bulloch Sector Microscope, as pictured in the Journal of the
RMS in 1880, where it was said to first have been exhibited in 1873.
It is unclear from the text if this was in England or in the
U.S.A. If in England, one would assume it dated to sometime before that
because of the long delays in transporting such goods across the
Atlantic. Note the Lister limb construction and the nosepiece
fine adjustment. Also notable is the fusee chain drive for one
axis of the mechanical stage.
