Platen Dissecting Microscope. 
No. 3790. 
The general design of this dissecting microscope may be gathered from the illustration. It 
possesses features which render it a most convenient instrument for prolonged work, the arm rests 
being of a large size, so that not only are the hands given support but also the forearms, giving far 
greater comfort. 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 listed, 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.
