"Supposing yourself to be the victim, how would you feel, if, when retiring to bed in some strange establishment, just as you were thinking of blowing out the candle, it should suddenly explode with no small report, the light be extinguished, and in place of the flame a small ghost with outstretched arms should appear, shining with a phosphorescent glow? I venture to think you would be very, very much surprised; and yet this is the effect produced by this ingenious construction."
Above the text are two drawings.
The first is a figure with a skull and arms along its side, stuffed within a tube, with a spring underneath, and this contraption inside a burning candle.
The second picture is that same figure, but now with outstretched arms, peaking out from the now-exposed tube, with the top of the candle now nowhere to be seen.
