DescriptionThis is a monocular compound microscope made by the English optician, Edward Bryan in the style of Society of Arts Prize microscopes.
The microscope has a claw-foot base of cast iron screwed to a wooden tray. The upright pillars are part of the same casting in the style of Crouch. The rest of the instrument is brass. The inclining joint is at their top and holds the stage, through the back of which is a cylindrical post. A triangular post rises up out of the cylinder by means of rack and pinion. It carries a horizontal bracket into which is screwed the straight monocular body tube. Fine focus is by means of a precision screw that operates a lever by the objective. The coarse focus is by rack and pinion.
The microscope has a circular stage with sliding super-stage manipulated by two handles. The handles also serve as rest for slides. There is one stage clip. The cylindrical post below the stage carries a fork-mounted concave mirror.
The mahogany standing case is fitted with a parts drawer with sections for slides. Parts of the case are cushioned with green wool.
The instrument has 3 Bryan objectives in canisters (3): 1/4, 1, 2 inch; 1 ocular; a live box; stage forceps of brass and steel; and a bull's eye condenser (lens missing) of brass and steel with circular base filled with lead.
In the drawer are 5 small and 12 large prepared glass slides, many with Victorian paper sleeves. Ten of the bigger slides have Bryan yellow or white stickers. Four of the small slides are Bourgogne. There is also an small empty ivory slide marked "Test. / No. 2" in ink, and a round box with round cover slips. The box is covered with yellow paper with black crisscrossing lines. There are also 5 powdered specimens, each in a folded sheet of blue paper identified with brown ink.
