Chinese Shadows.
Cut out an aperture in a partition wall, of any size; for example, four feet in length and two in breadth, so that the lower edge may be about five feet from the floor, and cover it with white Italian gauze, varnished with gum-copal. Provide several frames of the same size as the aperture, covered with the same kind of gauze, and delineate upon the gauze different figures, such as landscapes and buildings, analogous to the scenes which you intend to exhibit by means of small figures representing men and animals. These figures are formed of pasteboard, and their different parts are made movable, according to the effect intended to be produced by their shadows, when moved backward and forward behind the frames, at a small distance from them. To make them act with more facility, small wires, fixed to their movable parts, are bent backward, and made to terminate in rings, through which the fingers of the hand are put, while the figure is supported by the left, by means of another iron wire. In this manner they may be made to advance or recede, and to gesticulate, without the spectators observing the mechanism by which they are moved; and as the shadow of these figures is not observed on the paintings till they are opposite those parts which are not strongly shaded, they may thus be concealed, and made to appear at the proper moments, and others may be occasionally substituted in their stead.
It is necessary, when the figures are made to act, to speak a dialogue, suited to their gestures, and imitate the noise occasioned by different circumstances. The paintings must be illuminated from behind by means of a reverberating lamp, placed opposite to the centre of the painting, and distant from it about four or five feet. Various amusing scenes may be represented in this manner, by employing small figures of men and animals, and making them move in as natural a way as possible, which will depend on the address and practice of the person who exhibits them.
