34 LIVING PICTURES. Fig. lowered as seen in Fig. 33, wherein a clown is painted on a black background and over him slides a second glass bearing two black patches so arranged that one of the legs is covered while the iyV\ other is in full view. By a to-and-fro ^^ ' motion of the slipping glass the two differently posed legs are alter- nately shown, with the apparent result of a gymnastic perform- ance, which may be varied by the action of a second slipping glass arranged to alternately cover and uncover the duplicate lower portions of the raised legs, which then appear to work from the knee. Another toy, shown in Fig. 34, is of a very simple nature. A vertical spindle carries a set of four cards, projecting radially at angles of go degrees, the whole set being united and capable of rotation. In the four angles between the cards four successive positions of the same figure are shown. The set of pic- tures is rapidly rotated by the cards acting as vanes when blown upon, and it will be seen that one figure is observed when an angle is opposite the eye, while a picture compounded of the left- hand of one design and the right-hand of the next is seen when a card stands " edge-on." A further development of this was patented in 1895. The cards are independent, and instead cf travelling at a fixed rate, are stopped back, but when Fig. 34.
