Description is exactly
The monocular microscope has a Ross Y-shaped foot which is secured to a mahogany platform. The compound microscope is made of brass. The one-sided sub-stage mirror is attached to the bottom of the limb by a gimbal joint that allows it to be maneuvered to catch the light. Coarse focusing is achieved by a rack and pinion mechanism which is controlled by a thumbscrew at the side of the limb. The small thumbscrew at the back of the body-tube by the nose piece controls the fine focusing. The square fixed stage does not seem to have any means of securing specimens. The substage iris diaphragm that can be adjusted by rotating the disk. This microscope design followed the 1854 Society of Arts pattern. The fitted, solid mahogany case has brass hinge and handle. The lock is missing and the door is slightly warped. There are shrinkage cracks to the rear panel.
