Nearly identical to microscope inv. 3171, this reflecting microscope was invented 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 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. Accessories include four eyepieces, a lieberkuhn, and some items for handling specimens.
