THAUMATROPE, OR WONDER TURNER.

Cut out a disc of cardboard or pasteboard, and drill three holes near the edge on two opposite sides, in each of which tie a length of string. In the centre on one side paint a jockey seated, and on the other centre, upside down as compared with the man, a running horse.

Performances.—If you take the strings, one set in each hand, and whirl the disc round as on a horizontal axle, the strings will twist and keep up the movement, during which the two pictures will unite as one. Other objects may be a bird and cage, a juggler doing the knife or ball tossing trick, a rat and trap, &c.
