After travelling with Mortimer some time, Dale eventually returned to England, and retired from the profession. He opened a large shop in London under the firm name of H. & E. J. Dale, Manufacturing Electricians, 4 Little Britain, E. C., in October, 1882.

It was the easiest thing imaginable for Robert-Houdin to have his theatre arranged with secret confederates and wires back of the scenes, where a man with powerful opera-glasses could stand. The place being small, he could look all over the room and see the minutest article.

When not making use of the talking code, the simplest method employed by second-sight artists is to have a confederate in the audience, with either an electrical push button or a pneumatic bulb, who gives the medium the signal. This is received by a miniature piston, which requires only a small hole in the stage, while the medium has a matching hole in the sole of his shoe. This allows the piston to touch the sole of the foot whenever the confederate presses the bulb or pushes the button.

From this array of facts it will be seen that second sight is and always has been a matter of well-drilled phrases or signals, prearranged rotation of articles, well-built apparatus or well-trained confederates, but never a feat of actual thought-transferrence.

Some of Robert-Houdin’s ardent supporters insist that in claiming the invention or discovery of second sight, the French conjurer was merely an unconscious plagiarist, having stumbled upon, quite by accident, a trick which he did not know that others had offered before him.

Such a statement is illogical and absurd. Books of magic to which Robert-Houdin had access and which he admits having read describe the trick in a more or less crude form. Pinetti, whose tricks were fully described to Robert-Houdin by his old friend Torrini, used the second-sight mystification with excellent effect. Robert-Houdin could not have been ignorant of its existence as a trick. In making the claim to its discovery in his “Memoirs” he simply trusted to the ignorance of the reading public in the history of magic.

According to programmes and newspaper clippings in my collection, Philip Breslaw was the first conjurer to feature second sight in his performance. Breslaw was a clever German who so established himself in the hearts of amusement-loving Englishmen that he remained in England for forty years, dying in Liverpool in 1803. In 1781, while playing at Greenwood’s Rooms, Haymarket, London, he announced as Part One of his entertainment:
