Compound microscope

This compound microscope, similar to microscope inv. 3203, was made by Giovanni Battista Amici. The instrument is mounted on a tripod to which a square-sectioned pillar is fastened. The illumination mirror and the stage move along the pillar by rackwork. The stage is fitted with micrometer screws for X and Y motion. Below it is a circular diaphragm with three holes. Focusing is by adjusting the position of the stage relative to the body-tube attached horizontally to the pillar. An articulated arm holds a bull's eye lens in front of the body-tube. The body-tube can be removed and replaced by a support for holding a simple objective. The box contains many items including four eyepieces, a lieberkuhn, two camera lucidas, and accessories for handling specimens. Probable provenance: Lorraine collections.
