This drum-type brass compound microscope has a cylindrical housing, standing on a brass ring. Two sections of the housing are cut away to give access to the circular stage and allow light to the concave mirror below it. The body tube fits into a tube at the top of the housing and slides up and down for focusing. There are three objective lenses, stamped “1,” “2,” and “3.” They screw into the bottom end of the body tube. The eyepiece is Huygenian-type with two lenses and screws into the top of the body.


The following accessories fit into the wood carrying case:

1. Three objectives

2. Live box

3. Glass bottom tray for liquid specimens

4. Five prepared glass slides with mica covers

5. Forceps
