"Now, according to the principle of Father Kircher and the most learned chemists, who assert that the substantial form of bodies resides in the salts, and that these salts, set in motion by warmth, form the same figure as that which had been given to them by nature, it is not difficult to comprehend that dead bodies being consumed away in the earth, the salts which exhale from them with the vapors, by means of the fermentations which so often occur in this element, may very well, in arranging themselves above ground, form those shadows and phantoms which have frightened so many people. Thus we may perceive how little reason there is to ascribe them to the return of spirits, or to demons, as some ignorant people have done.
"To all the authorities by means of which I have combated the apparitions of spirits which are in purgatory, I shall still add some very natural reflections. If the souls which are in purgatory could return hither to ask for prayers to pass into the abode of glory, there would be no one who would not receive similar entreaties from his relations and friends, since all the spirits being disposed to do the same thing, apparently, God would grant them all the same permission. Besides, if they possessed this liberty, no sensible person could understand why they should accompany their appearance with all the follies so circumstantially related in those stories, as rolling up a bed, opening the curtains, pulling off a blanket, overturning the furniture, and making a frightful noise. In short, if there were any reality in these apparitions, it is morally impossible that in so many ages one would not have been found so well authenticated that it could not be doubted.
"After having sufficiently proved that all the apparitions which cannot be ascribed to angels or to the souls of the blessed are produced only by one of the three following causes—the extreme subtility of the senses; the derangement of the organs, as in madness and high fever; and the power of imagination—let us see what we must think of the circumstance which occurred at St. Maur.
"Although you have already seen the account that has been given of it, I believe, sir, that you will not be displeased if I here give you the detail of the more particular circumstances. I shall endeavor to omit nothing that has been done to confirm the truth of the circumstance, and I shall even make use of the exact words of the author, as much as I can, that I may not be accused of detracting from the adventure.
"Monsieur de S——, to whom it happened, is a young man, short in stature, well made for his height, between four and five-and-twenty years of age. Being in bed, he heard several loud knocks at his door without the maid servant, who ran thither directly, finding any one; and then the curtains of his bed were drawn, although there was only himself in the room. The 22d of last March, being, about eleven o'clock at night, busy looking over some lists of works in his study, with three lads who are his domestics, they all heard distinctly a rustling of the papers on the table; the cat was suspected of this performance, but M. de S. having taken a light and looked diligently about, found nothing.
"A little after this he went to bed, and sent to bed also those who had been with him in his kitchen, which is next to his sleeping-room; he again heard the same noise in his study or closet; he rose to see what it was, and not having found anything more than he did the first time, he was going to shut the door, but he felt some resistance to his doing so; he then went in to see what this obstacle might be, and at the same time heard a noise above his head towards the corner of the room, like a great blow on the wall; at this he cried out, and his people ran to him; he tried to reassure them, though alarmed himself; and having found naught he went to bed again and fell asleep. Hardly had these lads extinguished the light, than M. de S. was suddenly awakened by a shake, like that of a boat striking against the arch of a bridge; he was so much alarmed at it that he called his domestics; and when they had brought the light, he was strangely surprised to find his bed at least four feet out of its place, and he was then aware that the shock he had felt was when his bedstead ran against the wall. His people having replaced the bed, saw, with as much astonishment as alarm, all the bed-curtains open at the same moment, and the bedstead set off running towards the fire-place. M. de S. immediately got up, and sat up the rest of the night by the fire-side. About six in the morning, having made another attempt to sleep, he was no sooner in bed than the bedstead made the same movement again, twice, in the presence of his servants, who held the bed-posts to prevent it from displacing itself. At last, being obliged to give up the game, he went out to walk till dinner time; after which, having tried to take some rest, and his bed having twice changed its place, he sent for a man who lodged in the same house, as much to reassure himself in his company, as to render him a witness of so surprising a circumstance. But the shock which took place before this man was so violent, that the left foot at the upper part of the bedstead was broken; which had such an effect upon him, that in reply to the offers that were made to him to stay and see a second, he replied that what he had seen, with the frightful noise he had heard all night, were quite sufficient to convince him of the fact.
"It was thus that the affair, which till then had remained between M. de S. and his domestics, became public; and the report of it being immediately spread, and reaching the ears of a great prince who had just arrived at St. Maur, his highness was desirous of enlightening himself upon the matter, and took the trouble to examine carefully into the circumstances which were related to him. As this adventure became the subject of every conversation, very soon nothing was heard but stories of ghosts, related by the credulous, and laughed at and joked upon by the free-thinkers. However, M. de S. tried to reassure himself, and go the following night into his bed, and become worthy of conversing with the spirit, which he doubted not had something to disclose to him. He slept till nine o'clock the next morning, without having felt anything but slight shakes, as the mattresses were raised up, which had only served to rock him and promote sleep. The next day passed off pretty quietly; but on the 26th, the spirit, who seemed to have become well-behaved, resumed its fantastic humor, and began the morning by making a great noise in the kitchen; they would have forgiven it for this sport if it had stopped there, but it was much worse in the afternoon. M. de S., who owns that he felt himself particularly attracted towards his study, though he felt a repugnance to enter it, having gone into it about six o'clock, went to the end of the room, and returning towards the door to go into his bed-room again, was much surprised to see it shut of itself and barricade itself with the two bolts. At the same time, the two doors of a large press opened behind him, and rather darkened his study, because the window, which was open, was behind these doors.
"At this sight, the fright of M. de S. is more easy to imagine than to describe; however, he had sufficient calmness left, to hear at his left ear a distinct voice, which came from a corner of the closet, and seemed to him to be about a foot above his head. This voice spoke to him in very good terms during the space of half a miserere; and ordered him, theeing and thouing him to do some one particular thing, which he was recommended to keep secret. What he has made public is that the voice allowed him a fortnight to accomplish it in; and ordered him to go to a place, where he would find some persons who would inform him what he had to do; and that it would come back and torment him if he failed to obey. The conversation ended by an adieu.
"After that, M. de S. remembers that he fainted and fell down on the edge of a box, which caused him a pain in his side. The loud noise and the cries which he afterwards uttered brought several people in haste to the door, and after useless efforts to open it, they were going to force it open with a hatchet, when they heard M. de S. dragging himself towards the door, which he with much difficulty opened. Disordered as he was, and unable to speak, they first of all carried him to the fire, and then they laid him on his bed, where he received all the compassion of the great prince, of whom I have already spoken, who hastened to the house the moment this event was noised abroad. His highness having caused all the recesses and corners of the house to be inspected, and no one being found therein, wished that M. de S. should be bled; but his surgeon finding he had a very feeble pulsation, thought he could not do so without danger.
