him, to get him to speak, and related all the passages very exactly; after which he protested never to lie more in that room; upon which I set up a resolution to lodge in it again, not knowing but something of the reason of those troubles might by that means be imparted to me. The next night, therefore, I ordered a Bible, and another book to be laid in the room, and resolved to spend my time by the fire in reading and contemplation, till I found myself inclined to sleep: and accordingly having taken leave of the family at the usual hour, I addressed myself to what I had proposed, not going into bed till past one in the morning: a little after I was got into bed, I heard somewhat walk about the room, like a woman in a tabby gown trailing about the room; it made a mighty rushelling noise, but I could see nothing, though it was near as light as the night before: it passed by the foot of the bed and a little opened the curtains, and thence went to a closet door on that side, through which it found admittance, although it was close locked: there it seemed to groan, and draw a great chair with its foot, in which it seemed to sit, and turn over the leaves of a large folio; which you know make a loud clattering noise; so it continued in that posture, sometimes groaning, sometimes dragging the chair, and clattering the book till it was near day; afterwards I lodged several times in this room, but never met with any molestation.” “This I can attest to be a true account of what passed in that room the two described nights; and though Mr. C. be lately dead, who was a very ingenious man, and affirmed the first part unto many, with whom he was conversant; it remains that I appeal to the knowledge of those who have been inhabitants or lodgers in the said house, for what remains, to justify the credibility of the rest.” CHAP. IV. _Medical distinctions of spectral impressions. Sepulchral remedies: Preparations of the human skull--Mumia--Apparition of Ficinus to Michael Mercato.--Warning voice to Quarræus.--Visions of Dr. Pordage. Latent lunacy--Exemplified in the character of Hamlet._ In medicine, we have fine names, at least, for every species of disease. The peculiar disorder, which I have endeavoured to elucidate, is termed generally HALLUCINATION, including all delusive impressions, from the wandering mote before the eye, to the tremendous spectre, which is equally destitute of existence. It is unnecessary to my purpose, to pursue the subdivisions of this affection, which have been traced by nosologists. I shall only mention one extreme species, called the Lycanthropia, in which the patient imagines himself to have become a wolf, abandons society, and takes refuge in the woods. These impressions have no doubt been produced, or strengthened by narcotic potions, of hyoscyamus, datura stramonium, and other deleterious infusions, either ignorantly taken, or maliciously administered.
