Brief Description: This copper alloy instrument stands on an octagonal wooden box base with the horseshoe mount for the concave mirror at its centre. Three curved legs support the stage and body. The stage has two pinholes, a keyhole slot for accessories and two spring clips, shaped to hold glass phials, are attached to its underside. The body consists of a copper alloy cylinder fixed to the legs and an inner draw tube that slides up and down for focusing. A lignum vitae fitting holding the eye lens and field lens screws into a collar, also lignum vitae, set on the top of the sliding tube. A tubular copper alloy nose screws into a disk at the lower end of the draw tube that has an external thread for objectives. A Lieberkühn carrier is attached to the microscope. The octagonal base has a drawer containing five objectives, a circular spring stage, a Lieberkühn in a can, a fishplate, a live box and three ivory sliders all containing specimens. The wooden pyramid case also has a drawer containing a black disc and seven glass slides. Three of the slides contain specimens and are wrapped with coloured paper, the remaining four slides are unused.
