The microscope came equipped with two eyepieces and four objectives numbered 0, 4, and 7, and 9. Within the tube is a Bertrand lens and an analyzing Nicol prism, both on sliding mountings. The focusing sub-stage holds a polarizer with a three element condenser. The top two elements can be moved aside for low power work using a lever mounted on the side of the stage.

The following was extracted form The Journal of the Royal Microscopical Society, 1892

Fuess Microscopes - The Fuess model No. II. (fig. 68) is similar to the larger instrument described in this Journal, 1891, p. 393. The stand can be inclined to the horizontal. The rotating stage is divided into 360°, with two verniers reading to 5 minutes. It can be fixed in any position by means of a lever. The polarizer has a rack and pinion motion. In its socket fit the various illuminating apparatus, which can be centered by slide pieces provided with screws. Arrangements for obtaining convergent and parallel light can be inserted. The mechanical stage (fig. 72, p. 669) is similar to that of the larger model, but has no micrometer measuring arrangement. All the special eye-pieces and other accessories of the model No. I. can be used with this instrument. Model No. III. (fig. 69) does not differ very much from the proceeding. The stage is provided with cross-divisions for the orientation of the preparation; but if required the mechanical stage of model No. II can also be applied to this instrument. The draw-tube is only movable by hand, and carries no millimeter divisions.

The tail of the microscope is engraved with the initials O.S.U. along with a corresponding inventory number. The same markings are stamped on the top of the storage case. Evidently, at one time, this instrument was in use at Ohio State University. Sometime in the 1980's Ernest Ehlers, a professor of Mineralogy at Ohio State University, purchased this microscope when the University was disposing of older equipment. It was obtained for this collection from his widow.
