Show TWO ODD OPTICAL ILLUSIONS Actual Measurement of Two Figures Shown Will Prove That They ' Are of Exact Size. The picture on the left represents two figures in a gallery. At first sight no one would doubt that the man at the top of the illustration wa3 by far the taller, but an actual measurement measure-ment of the two figures will show that they are precisely the same height The picture on the right gives the Impression that the two thick black lines are curved, but on examination it will be found that they are perfectly perfect-ly parallel. The lines which diverge i Optical Illusions. from that center cause the illusion, for they lead the lines of vision away, making it appear that the b'ack lines-are lines-are further apart at the center than they are at their ends. If the drawing is held edgeways to the eye it will be seen that they are exactly true. |
