BROWNING'S PLATYSC0PIC LENS. 



A NEW ACHROMATIC COMBINATION, 



Combining the definition of a Microscope with the 

 Portability of a Pocket Lens. 



" If you carry a small Platyscopic Pocket Lens (which every observer of 

 Nature ought to do)." — Grant Allen in K?wwlcdge. 



The Platyscopic Lens is invaluable to botanists, mineralogists, or entomologists, 

 as it focuses about three times as far from the object as the Coddington Lenses. 

 This allows opaque-objects to be examined easily. 



The Platyscopic Lens is made of four degrees of power, magnifying respectively 

 io, is, 20, and 30 diams. ; the lowest power, having the largest field, is the best 

 adapted for general use. 



The Lenses are set in Ebonite Cells, and mounted in Tortoiseshell Frames.
