The Platyscopic Lens is invaluable to botanists, mineralogists. or entomologists, as it focuses about three times as far from the object as the Coddington Lens, and has a field unequalled for flatness, allowing opaque objects to be examined easily. It is made in four degrees of power, magnifying respectively 10, 15, 20, and 30 diams. ; the lowest power, having the largest field, is the best adapted for general use.
