An English lacquered brass portable aquatic microscope, unsigned, second quarter of the 19th century With square section post fitted with lens above friction sliding up/down adjustable stage with ivory slip insert and tool post holes to rim, with pivoted mirror beneath and mounted via a sliding socket onto an oval brass foot, the velvet lined maroon morocco leather covered box with accessories including two additional lenses, forceps, tweezers, a specimen capsule and three bone sliders, 11cm (4.25ins approx.) wide. The design of the current lot is probably derived from a model developed by John Ellis in around 1752. The main difference being that the current lot focuses by up/down movement of the stage rather than the lens.
