Cornex Dissecting Microscope. 
For class use this dissecting microscope will be found most Pee oe as although it is of 
the simplest construction, it is very rigid and strong, and the magnification given is all that is 
required for ordinary botanical and entomological dissection. For naturalists’ work and for such 
purposes as the recognition of diseases in bees and other insects it will be found equally useful. 
The Cornex dissecting microscope is constructed from a solid Llock of wood and in use will 
be found very convenient. The sides of the block are cut away at an angle so as to form 
rests for the hands. A glass stage is provided upon which to place the objects, which are illumin- 
ated by a mirror set at an angle of 45°. 
The lenses are carried in an arm which is attached to a rod, the rod b2ing held in a tubular 
fitting which allows it to be slid up and down for focussing purposes and also to b> swung over 
the stage plate so that objects at different positions can be examined. 
With the lenses supplied, magnifications of 7 and 14 are obtained. These lenses are so 
arranged that they can be used either separately or combined, the higher power being obtained 
with the two lenses together, the lower power when used separately. 
Holes are provided in the top of the microscope into which the lenses can be placed for 
storage purposes when the instrument is not in use.
