This case-mounted microscope, when assembled with the compound tube, is 11½-inches in height measuring from the table top. The case dimensions are 6 x 5¼ x 1½-inches. It is unsigned by the maker and is likely English dating from the mid-19th century. The main focusing adjustment is accomplished by sliding the stage up and down along the cylindrical pillar, while the knob on top of the pillar functions as a fine focus adjustment by moving the optics. The microscope comes supplied with a Huygenian eyepiece and four separate objectives of different magnifications that are used singly. In addition, it is supplied with a brass trough with glass bottom for wet work, a glass stage insert, and stage clips. The microscope can be use with or without the compound tube.
