Compound microscope, similar to microscope inv. 3201, made by Giovanni Battista Amici. The instrument is mounted on a square-sectioned pillar on the box, which can carry the microscope with its accessories. The illumination mirror and the stage (fitted with a micrometer movement) move along the pillar by rackwork. The image is focused 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. Some of the accessories were made by Vincent & Charles Chevalier in Paris. Provenance: Lorraine collections.
