Brass Culpeper Type Microscope in Case with Accessories, English, c. 1775-1800

This is an early example of a brass Culpeper-type microscope. The instrument stands on a wooden box base with a socket for a concave mirror at its centre. Three scrolled legs support the circular stage and body. The stage has a keyhole slot and two pinholes for accessories. Two spring clips, shaped to hold glass phials, are attached to the underside of the stage. The body tube slides into a sleeve mounted above the stage. It has an eye lens and a field lens. The cylindrical nosepiece has an external thread for the objectives and attaches to a wooden collar on the base of the body tube. The base holds five objectives, a circular spring stage, a cone condenser, a fishplate, an ivory disk, a Lieberkühn, a Lieberkühn carrier, a sub-stage mirror and knob on a pin. The pyramid case is oak.
