THE GEOMETRICAL FIGURE TEST.
DEMONSTRATION XI. Have the audience select some simple geometrical figure, such as a square, triangle, circle, right angle, etc., and proceed to draw it in the same way as the figures in the demonstrations just described. Have the Transmitter hold the figure in his mind and mentally draw it as you proceed. A little private practice will enable you to draw these figures easily, and in fact, they are really simpler than numbers, although more startlingly effective at times.
