Compound microscope made by Nachet in Paris. Was designed mainly for demonstrations to students during lectures. The instrument, mounted on a bar attached to a base carrying a mirror, can also be removed from the base and held by means of a wooden handle (now missing). Two metal arms formed a tripod with the handle for putting down the microscope. Coarse focus is by sliding the body, fine focus by a screw. There was a substage condenser (now missing).
