Bausch and Lomb Optical Co.'s Physician's Microscope - The special features of this instrument (fig. 114) are the fine adjustment (described in Vol. II., 1882, p. 683), the cradle-joint for inclining, and the glass stage. The latter rests on a forked support and could be made to give in a different form one advantage of Mr. Nelson's divided stage, as with glass the position of the illuminating apparatus would be readily seen. The slide-carrier would, however, require to be altered, so as not to impede the view beneath the stage. There is a removable substage and diaphragm. The pillar and arm, in the original form, were marked so as to indicate the correct inclination of the body in the use of the camera lucida. The mirror is attached to a swinging tail-piece.
The microscope shown on this page is an example of a later version Physician's model. It differs from the one described in the Journal in having a brass tripod base as opposed to the more typical cast iron claw base and in having the upper section of the draw-tube nickel plated. It is otherwise very similar to the illustrated microscope. This instrument represents a final version of this model. By the end of the century, the microscopes produced by the firm were largely in the 'continental' style. Two earlier versions of the Physician's model from 1879 and 1883 are also represented in this collection.
This model was also described in the Sharp & Smith Catalog of Surgical Instruments, 1889 as follows:
