the element in question. To use the instrument the object should be focussed and brought into the centre of the field and the object marker substituted for the objective. The object marker screws to the microscope tube or the nosepiece after the manner of an objective.

The diamond point is placed slightly out of centre and in the act of being rotated rules a small circle upon the cover-glass.............................................0.10. 0 Markirer

175. Demonstrating- Eyepiece. (Pointer Eyepiece, as devised by Kuznizky). This eyepiece serves the purpose of pointing out special features in the field. It contains a pointer which may be directed by a small external lever.

By this movement in conjunction with the rotation of the eyepiece within the tube the demonstrator is enabled to direct attention to any point in the field of view . . 0. 8. 0 Indicator

Double Demonstrating- Eyepiece. This device slides into the tube of the microscope like an ordinary eyepiece. It contains above the plane of the eyepiece stop an arrangement of prisms by means of which the image formed by the objective can be viewed simultaneously by two observers.

Double Demonstrating Eyepiece No. 176.

To enhance the utility of this double eyepiece as a means of demonstrating microscopic objects it is fitted in the plane of the stop, which is the plane where the image is formed, with a movable pointer that can be seen by both observers and which enables either to indicate any element to which he wishes to direct the attention of the other. To this end the pointer is so arranged that it may be pushed in and out, and, in addition, it may be made to describe radial movements about a ball point.

To compensate differences in the sight of the two observers the eyepiece at the side is so arranged that it may be adjusted independently.
