Mechanically I turned round the miniature to examine the back of it, and on the back was engraved a pentacle; in the middle of the pentacle a ladder, and the third step of the ladder was formed by the date 1765. Examining still more minutely, I detected a spring; this, on being pressed, opened the back of the miniature as a lid. Within-side the lid were engraved, "Marianna to thee. Be faithful in life and in death to ----." Here follows a name that I will not mention, but it was not unfamiliar to me. I had heard it spoken of by old men in my childhood as the name borne by a dazzling charlatan who had made a great sensation in London for a year or so, and had fled the country on the charge of a double murder within his own house,--that of his mistress and his rival. I said nothing of this to Mr. J----, to whom reluctantly I resigned the miniature. We had found no difficulty in opening the first drawer within the iron safe; we found great difficulty in opening the second: it was not locked, but it resisted all efforts, till we inserted in the chinks the edge of a chisel. When we had thus drawn it forth, we found a very singular apparatus in the nicest order. Upon a small, thin book, or rather tablet, was placed a saucer of crystal; this saucer was filled with a clear liquid,--on that liquid floated a kind of compass, with a needle shifting rapidly round; but instead of the usual points of a compass were seven strange characters, not very unlike those used by astrologers to denote the planets. A peculiar but not strong nor displeasing odor came from this drawer, which was lined with a wood that we afterwards discovered to be hazel. Whatever the cause of this odor, it produced a material effect on the nerves. We all felt it, even the two workmen who were in the room,--a creeping, tingling sensation from the tips of the fingers to the roots of the hair. Impatient to examine the tablet, I removed the saucer. As I did so the needle of the compass went round and round with exceeding swiftness, and I felt a shock that ran through my whole frame, so that I dropped the saucer on the floor. The liquid was spilled; the saucer was broken; the compass rolled to the end of the room, and at that instant the walls shook to and fro, as if a giant had swayed and rocked them. The two workmen were so frightened that they ran up the ladder by which we had descended from the trapdoor; but seeing that nothing more happened, they were easily induced to return. Meanwhile I had opened the tablet: it was bound in plain red leather, with a silver clasp; it contained but one sheet of thick vellum, and on that sheet were inscribed, within a double pentacle, words in old monkish Latin, which are literally to be translated thus: "On all that it can reach within these walls, sentient or inanimate, living or dead, as moves the needle, so work my will! Accursed be the house, and restless be the dwellers therein."
