“When so strange a wonder can be wrought under such circumstances by means so simple, we cannot but feel the force of Dr. Lodge’s warning that an unwavering scepticism ought to be the attitude of all honest investigators toward every one who professes to be able to suspend the operation of a custom of nature. No one of the feats attributed to Home, the celebrated medium who plied his trade in Paris during the Second Empire, was more abnormal than this trick of Cagliostro’s Casket, and no one of them is so well authenticated. It may be that certain of the customs of nature are not inexorable and that we shall be able to discover exceptions now and again. But the proof of any alleged exception, the evidence in favor of any alleged violation of the custom of nature, ought to be overwhelming.” {150} V. The greatest event of Houdin’s life was his embassy to Algeria, “at the special request of the French Government, which desired to lessen the influence of the Marabouts, whose conjuring tricks, accepted as actual magic by the Arabs, gave them too much influence.” He went to play off his tricks against those of Arab priests, or holy men, and, by “greater marvels than they could show, destroy the _prestige_ which they had acquired. He so completely succeeded that the Arabs lost all faith in the miracles of the Marabouts, and thus was destroyed an influence very dangerous to the French Government.” His first performance was given at the leading theatre of Algiers, before a great assemblage of Arabs, who had been summoned to witness the _soirée magique_, by the mandate of the Marshall-Governor of Algeria. Houdin’s “Light and Heavy Chest” literally paralyzed the Arabs with astonishment. He altered the _mise en scène_, and pretended to be able to make the strongest man so weak that he would be unable to lift a small box from the floor. He says in his memoirs: “I advanced with my box in my hand, to the center of the ‘practicable,’ communicating from the stage to the pit; then addressing the Arabs, I said to them: “ ‘From what you have witnessed, you will attribute a supernatural power to me, and you are right. I will give you a new proof of my marvelous authority, by showing that I can deprive the most powerful man of his strength and restore it at my will. Any one who thinks himself strong enough to try the experiment may draw near me.’ (I spoke slowly, in order to give the interpreter time to translate my words). “An Arab of middle height, but well built and muscular, like many of the Arabs are, came to my side with sufficient assurance. “ ‘Are you very strong?’ I said to him, measuring him from head to foot. “ ‘Oh yes!’ he replied carelessly. “ ‘Are you sure you will always remain so?’ “ ‘Quite sure.’ “ ‘You are mistaken, for in an instant I will rob you of your strength, and you shall become like as a little child.’ {151} “The Arab smiled disdainfully, as a sign of his incredulity. “ ‘Stay,’ I continued; ‘lift up this box.’
