In order to appear upright upon the visible stage the actor or object on the hidden stage should be inclined so as to be as nearly as practicable parallel with the surface of the glass screen. In effecting this assistance is afforded by the screen _k_ of the hidden stage. Several sheets of glass may be similarly employed at the same time if one is not of sufficient width to cover the different parts of the stage at which it is desired that the spectre should appear, the interval or junction being concealed by the introduction of a tree or column or some other piece of scenery. Having thus described the nature of our Invention and the manner of performing the same, we would have it understood that we make no claim to any of the parts separately, but what we claim is the combined arrangement as herein described of a glass inclined forwards towards the audience, and two stages, one the ordinary visible stage, and the other a hidden stage at a lower level than the ordinary visible stage and illuminated with a much stronger light than either the ordinary visible stage or the body of the house, and which light is capable of being instantaneously, or, if so required, gradually withdrawn and restored. In witness whereof, I, the said John Henry Pepper, have hereunto set my hand and seal, this Thirty-first day of October, in the year of our Lord One thousand eight hundred and sixty-three. J. H. PEPPER. (L.S.) Returning to the author’s narrative:—The Ghost illusion was first shown in what was called the small theatre of the Royal Polytechnic, but as the audience increased so rapidly it was removed by the following Easter and shown on a grander scale in the large theatre of the Institution, and where the dissolving views were usually exhibited. The late Mr. O’Connor, of the Haymarket, painted the first scene used, representing the laboratory of “The Haunted Man,” which Christmas story the late Charles Dickens, by his special written permission, allowed me to use for the illustration of the Ghost illusion. This ghost scene ran for fifteen months, and helped to realise, in a very short time, the sum of twelve thousand pounds, not counting what I received for granting licences to use the Ghost, and also the sums realised during many successive years as new ghost stories were brought out. Sylvester now patented the use of looking-glass in the performance of the Ghost, which I thought very good, and bought of him—he could only infringe my patent by attempting to use it, and therefore his patent was useless to anybody else but myself. Mr. King, of Bath, brought out what he termed a “New Patent Ghost”; but my solicitors, Messrs. Hughes, Masterman, and Hughes, very soon quashed the alleged patent by appearing against Mr. King, when he tried to get his patent passed before the Solicitor-General, the result of which is thus described by
