into a routine process of visual optics by alan hodgkinson, who uses it with exceptional skill and success.  The method is best applied in a darkened room with a single light source, which may be either a clear electric bulb with 'C' filament or (more conveniently) a small 'slit' torch of the type produced by hanneman lapidary specialist (figure 3.2). the stone to be examined, if large or mounted with an open baking, can be held in the hand, or if small in tongs. When a doubly refractive stone is too small or has to low a birefringence to show doubling at all easily by the straight forward lens
