This brass compound microscope has two sets of three S-shaped supports. The top set supports the body tube. The bottom set supports the round stage and is fastened to the square wooden base. An inner tube, holding the lenses, slides up and down in the body tube for focusing. There are three internal springs in the body tube to maintain tension between the two tubes. The only remaining objective is a single lens that screws into the end of a long brass nosepiece at the bottom of the inner tube. It is marked “5.” The eyepiece is a two lens Huygenian-type and screws into the top end of the inner tube. The original eyecup is missing and has been replaced with a modern type. Illumination is by a single-sided concave mirror, attached to the wood base. There is also a bull’s eye lens that mounts in a hole on the stage. A Bonnani spring plate holds mounted specimens. Two substage spring clips and a slot on the stage are for attaching accessories. The microscope is signed “Dollond London” on the top of the stage. It comes with a pyramidal mahogany carrying case that has a bottom drawer for accessories.
