Drum Compound Microscope

Drum Compound Microscope

Biology

"A large drum microscope with two rack and pinion sets, one for coarse focus and one for varying tube length. The latter must be the "Grossissement variable." The lead-filled base has a square opening for illuminating the flat/concave substage mirror rotatable only about a horizontal axis. The stage and upper parts of the stand can be rotated on the base. A vertical pillar holds an arm and the tubes, but there is no fine focus provided." - Harvard University
