“With your back to the audience, you can telegraph in a similar way, using your arm and elbow to make the necessary signals. Let the right arm, hanging down, represent No. 1; the elbow, projecting from the side, No. 2; elbow raised, No. 3. Repeat {198} with the left arm for Nos. 4, 5 and 6; with either hand placed naturally behind you, on the small of the back, above the belt and over your shoulder for Nos. 7, 8 and 9, and on the back of your head or neck for the cipher (0).” III. It is an interesting fact to note that the Chevalier Pinetti was the first exhibitor of the second-sight trick. Houdin revived (or re-invented) it. [Illustration: SECOND-SIGHT TRICK.—SIGNALING.] On the 12th of December, 1846, he announced in his bill, “In this programme, M. Robert-Houdin’s son, who is gifted with marvelous second sight, after his eyes have been covered with a thick bandage, will designate every object presented to him by the audience.” In his memoirs he thus describes how he came to invent the trick: “My two children were playing one day in the drawing-room at a game they had invented for their own amusement. The younger had bandaged his elder brother’s eyes, and made him guess at the objects he touched, and when the latter happened to guess right, they changed places. This simple game suggested to me the most complicated idea that ever crossed my mind. “Pursued by the notion, I ran and shut myself up in my workroom, and was fortunately in that happy state when the mind {199} follows easily the combinations traced by fancy. I rested my head in my hands, and, in my excitement, laid down the first principles of second sight.” Houdin never revealed his method of working the trick. Robert Heller’s successors in mental magic are Max Berol and wife, and the Zancigs. Among other feats Berol is able to memorize over two hundred words called out by the spectators and written down on a slip of paper by some gentleman. Berol will then write these words backwards and forwards without hesitation and name any one of them by its number in the list. The Zancigs are marvels in the art of second sight. They were born in Copenhagen, Denmark, but are naturalized citizens of the United States. Clever advertisers, they lay claim to occult powers, as the following notice in the Washington Post, April 30, 1905, will testify:
