The pillar holds the illumination mirror, a stage, and the objective changer. The instrument has two lenses with a lieberkuhn and two other, more powerful objectives. There is a stage forceps for holding specimens. This type of microscope was designed by John Ellis. Provenance: Lorraine collections.
