"'Recreant! obscure Nicodemus, coming slinking in like a sleep-walker, interrupting the most important and interesting experiments. Let me tell you that a phenomenon which the incredulous have, without a moment's hesitation, classed in the category of the fabulous has just been verified by the present company. We wished to try whether the pendulum-oscillations of a suspended ring could be controlled by the concentrated human will. I undertook to fix my will upon it; and thought steadfastly of circular-shaped oscillations. The ring--fixed to the ceiling by a silk thread--remained motionless for a very long time. But at last it began to swing, in an acute angle with reference to my position, and it was just beginning to swing in circles when you came in and interrupted us.'" "'But what if it were not your will,' I said, so 'much as the draught of air when I opened the door, which set the contumacious ring in motion?' "'Prosaic wretch!' cried Vincent: but everybody laughed." "The pendulum-oscillations of rings drove me nearly crazy at one time," said Theodore. "Thus much is matter of absolute certainty, and any one can convince himself of it, that the oscillations of a plain gold ring, suspended by a fine thread over the palm of the hand held level, unquestionably take the direction which the unuttered will directs them to take. I cannot tell you how profoundly, and how eerily, this phenomenon affected me. I used to sit for hours at a time making the ring go swinging in the most various directions, as I willed it to do; and at last I went the length of making a regular oracle of it. I would say, in my mind, if such and such a thing is going to happen, the ring will swing in the direction between the little finger and the thumb; if it is not going to happen, it will swing at right angles to that direction, and so on."' "Delightful!" said Lothair, "you set up, within your own self, a higher spiritual principle, which, conjured up in mystic fashion by yourself, should make utterances to you. Here we have the true "spiritus familiaris," the socratic dæmon! from hence there is only a very short step to the region of ghost, and haunting stories, which might easily have their _raison d'être_ in the influence of some exterior spiritual principle." "And I mean to actually take this step," said Cyprian, "by telling you, on the spot, the most awful and terrible supernatural story I have ever heard of. The peculiarity of this story is, that it is amply vouched for by persons of credibility, and that the manner in which it has been brought to my knowledge, or recollection, has to do with the excited, or (if you prefer to say so) disordered condition which Lothair observed me to be in a short time ago." Cyprian stood up; and, as was his habit when his mind was full of something, so that he had to take a little time to arrange his words in order to express it, he walked several times up and down the room. Presently he sat down, and began:--
