This trick, however curious it may seem, is managed easily enough. I shall describe it. As soon as I was alone in my chamber, I took out of my pistol-case (which I carry with me wherever I go) a ball-mould. I took a card, turned up its corners and made a sort of recipient of it, in which I placed a lump of stearine, taken from one of the candles in the room. As soon as the stearine was melted, I mixed a little lamp-black with it—which I obtained by holding a knife over a lighted candle—and then I poured this composition into my ball-mould. If I had allowed the liquid stearine to become entirely cold, the ball would have been solid; but after ten or twelve seconds I reversed the mould, and the portion of the stearine which was not yet solid flowed out and left a hollow ball in the mould. This, by the way, is the mode in which the hollow candles used in the churches are made; the thickness of the sides depends on the time the melted stearine or wax is left in the mould. I wanted a second ball. I made it a little thicker than the first. I filled it with blood, and I closed the aperture with a drop of stearine. An Irishman had showed me years before, how to extract blood from the thumb without pain: I adopted his trick to fill my ball with blood. It is hard to believe how nearly these projectiles of stearine, colored with lamp-black, look like lead: they will deceive anybody, even when examined quite closely. The reader now clearly sees through the trick. While exhibiting the lead bullet to the spectators, I changed it for my hollow ball, and this last I ostensibly placed in the pistol. I rammed it down, to break the stearine into small pieces, which could not reach me at fifteen paces. As soon as the pistol was discharged, I opened my mouth and exhibited the lead ball between my teeth. The second pistol contained the ball filled with blood, which was broken to pieces on the wall, where it left the spot of blood, while the pieces of stearine could no where be found. This is the whole mystery. Weather-Wisdom. SHERIDAN’S RHYMING CALENDAR.
