Microscope. I do not claim any originality for this method of 

 working, for my attention was first drawn to it by a veteran 

 microscopist, the late Dr. F. Bussey, who told me he had employed 

 it many years ago, I think in the early "sixties," with a box- 

 form wet-plate camera and a monocular Microscope. As a simple 

 and (juick way of producing photomicrographs of low and medium 

 magnification, and with the Stereo-binocular Microscope, it will be 

 found very useful.
