This case-mounted Gould type microscope is signed on the stem “Porter & Hunt, London”.
The case measures 5.5 x 6.4 x 2 inches. Among the accessories supplied are four
objectives that are designed to be used singly, one of which is very high power
and is used without the compound tube, another objective with Lieberkuhn reflector,
a live box, a stage-mounted bullseye condenser, a stage forceps, a hand forceps,
two stage disk inserts, a dissecting tool, and a selection of sliders.
Note that the limb can be unscrewed from the main body of the microscope and in
conjunction with the Lieberkuhn objective and stage forceps, it can be converted
into a compass microscope. The image below, taken from the 1838 London Gasette,
is an announcement that the partnership between Porter and Hunt was terminated.
