Brief Description: The largest of Martin's microscopes, called the 'Grand Universal' (two others known). The long pillar of triangular section is attached by a hinged joint to a flat tripod. Each leg is in the form of an open-work curve terminating in a pedestal. The back of the pillar is cut with rackwork that adjusts the positions of the plano-concave mirror and the stage. The body, mounted on an arm at the top of the pillar, is in two sections, each with its own rackwork. There is a stage with three wings to take accessories including a crescent of seven wet cells. Because of its height, it was meant to stand on its own triangular-based cabinet when being used. Accessories are contained inside the cabinet in various cases and drawers, and in a separate chest. The accessories displayed are in their drawer. They comprise: ten objective lenses for use with the compound body, six lenses set in lieberkuhns and four high power lenses for use in the simple microscope mode. There are also three lieberkuhns and a porcelain substage mirror.
