Cornex Dissecting For class use this dissecting microscope will be found most satisfactory, 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 block 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 b?ing 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 cither 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. No. 33B.
