- adj. a microscope consisting essentially, first, of a mirror for reflecting a beam of sunlight through the tube, which sometimes is fixed in a window shutter; secondly, of a condenser, or large lens, for converging the beam upon the object; and, thirdly, of a small lens, or magnifier, for throwing an enlarged image of the object at its focus upon a screen in a dark room or in a darkened box.

A relentless inquisition drags every secret to the day, turns the glare of this solar microscope on every malfaisance, so as to make the public a more terrible spy than any foreigner; and no weakness can be taken advantage of by an enemy, since the whole people are already forewarned.
