The stage is 6" square and is recessed to receive either a glass plate or a brass plate with stage clips. Thus with the glass plate large, unmounted specimens can be accommo- dated for dissecting or examination and by using the brass stage with its stage clips specimens mounted on glass slides ean be used. The mirror is of extra large size, opal glass on one side, and silvered on the other. Either the Binomax magnifier or the Greenough binocular can be used on this microscope (see descriptions, pages 54 to 59). The addition of wide field eyepieces, as fisted, is of great advantage, giving a very large field for dissecting. For example, with the Binomax magnifier, at eight magnifications, the field of view is 35 m/m. No. 3790. No. No. 3791. 3791a.
