Among the causes of nervous affection and diseased imagination, are those of sedentary habits and a free use of strong tea. The following instances were communicated by my friend the Rev. Mr K.

The late Rev. Mr F. of Ipswich, who was very sedentary; spent most of his time in his study without exercise, and his health became impaired. He imagined for some time before his death, that he was actually dead. I saw him in this state of mind, walking his chamber in extreme agitation. To the question, how he could suffer so much, if actually dead, he answered, that his own spirit was departed, and that another spirit had taken possession of his body.

A gentleman in Boston once told the first President Adams, that he had become strangely timid, that he dared not keep the side walks, but walked in the middle of the street, being constantly apprehensive that the tile on the houses would fall on his head. The president asked him if he made a free use of tea, and being answered in the affirmative, he recommended to him to use it more sparingly and he would probably be benefited by the change. By pursuing this advice, he was relieved, and was soon able to return to the side walks without fear.

A gentleman of Salem, sailing from the south to Massachusetts, while under the influence of nervous affection, imagined that he saw a man in the water near the ship, who was drowning. Conceiving that he might save his life, he was in the very act of leaping into the sea for that purpose, but was happily prevented by those on deck. He afterward recovered his health, and had a perfect recollection of his feelings on that occasion. He had no idea of destroying himself, but would have perished had he not been prevented. Instances of a similar nature have probably occurred, in which lives have been lost in consequence of such delusion.

It is said that Mr Murdock, the member of the Vermont Legislature, who recently committed suicide, imagined himself to be Dr Cleaveland, who was under sentence of death. Mr Murdock attempted to speak when Cleaveland’s case was before the legislature, but was so much agitated that he could not speak, and was taken from the house by his friends. Under this strong impression of his being Cleaveland, he killed himself to avoid the doom of the law. This event would make a thrilling chapter in Sir Walter Scott’s history of Demonology and Witchcraft.

It will aid our purpose to relate the following instance of Mr Nicolai, an intelligent bookseller and member of the Academy of Sciences of Berlin, who happily possessed philosophy enough to account for the phantasms which, for some time agitated his own mind, upon rational principles. ‘In the year 1791, I was much affected in my mind by several incidents of a very disagreeable nature; and on a certain day a circumstance occurred, which irritated me extremely. At ten o’clock in the forenoon, my wife and another person came to console me. I was in a violent perturbation of mind, owing to a series of incidents which had altogether wounded my moral feelings, and from which I saw no possibility of relief; when suddenly I observed at the distance of ten paces from me, a figure; the figure of a deceased person. I pointed at it, and asked my wife if she did not see it. She saw nothing; but being much alarmed, endeavored to compose me, and sent for the physician. The figure remained seven or eight minutes, and at length I became a little more calm; and as I was extremely exhausted, I soon afterwards fell into a troubled kind of slumber, which lasted for half an hour. The vision was ascribed to the great agitation of mind in which I had been, and it was supposed I should have nothing more to apprehend from that cause; but the violent affection had put my nerves into some unnatural state; from this arose further consequences which require a more detailed description. In the afternoon a little after four o’clock, the figure which I had seen in the morning again appeared. I was alone when this happened, a circumstance, which, as may easily be conceived, could not be very agreeable. I went therefore to the apartment of my wife, to whom I related it. But thither also the figure pursued me. Sometimes it was present, sometimes it vanished, but it was always the same standing figure. A little after six o’clock, several stalking figures also appeared, but they had no connexion with the standing figure. The figure of the deceased person never appeared to me after the first dreadful day; but several other figures showed themselves afterwards very distinctly; sometimes such as I knew, mostly however, of persons I did not know, and amongst those known to me, were the semblance of both living and deceased persons, but mostly the former; and I made the observation, that acquaintance with whom I daily conversed never appeared to me as phantasms; it was always such as were at a distance. These figures appeared to me at all times, and under the most different circumstances, equally distinct and clear. Whether I was alone or in company, by broad day light equally as in the night time, in my own house as well as in my neighbor’s; yet, when I was at another person’s house, they were less frequent, and when I walked the public street, they very seldom appeared. When I shut my eyes, sometimes the figures disappeared, sometimes they remained even after I closed them. If they vanished in the former case, on opening my eyes again, nearly the same figures appeared which I had seen before. For the most part I saw human figures of both sexes; they commonly passed to and fro, as if they had no connexion with each other, like people at a fair, where all is bustle; sometimes they appeared to have business with each other. Once or twice I saw amongst them persons on horseback, and dogs and birds; these figures all appeared to me in their natural size, as distinctly as if they had existed in real life, with the several tints on the uncovered parts of the body, and with all the different kinds and colors of clothes. On the whole, the longer I continued in this state, the more did the phantasms increase, and the apparitions became more frequent. About four weeks afterwards, I began to hear them speak, sometimes the phantasms spoke with one another; but for the most part they addressed themselves to me; these speeches were in general short, and never contained anything disagreeable. Intelligent and respected friends often appeared to me, who endeavored to console me in my grief, which still left deep traces on my mind. This speaking I heard most frequently when I was alone; though I sometimes heard it in company, intermingled with the conversation of real persons, frequently in single phrases only, but sometimes even in connected discourse. Though at this time I enjoyed rather a good state of health both in body and mind, and had become so familiar with these phantasms, that at last they did not excite the least disagreeable emotion, but on the contrary afforded me frequent subjects for amusement and mirth; yet as the disorder sensibly increased, and the figures appeared to me the whole day together, and even during the night, if I happened to awake, I had recourse to several medicines. Had I not been able to distinguish phantasms from phenomena, I must have been insane. Had I been fanatic or superstitious, I should have been terrified at my own phantasms, and probably might have been seized with some alarming disorder. Had I been attached to the marvellous, I should have sought to magnify my own importance, by asserting that I had seen spirits; and who could have disputed the facts with me? In this case, however, the advantage of sound philosophy and deliberate observation may be seen. Both prevented me from becoming either a lunatic or an enthusiast; for with nerves so strongly excited, and blood so quick in circulation, either misfortune might have easily befallen me. But I considered the phantasms that hovered around me as what they really were, namely, the effects of disease, and made them subservient to my observations, because I consider observation and reflection as the basis of all rational philosophy.’ This gentleman had been accustomed to lose blood twice a year, but it was omitted at this time, and having suffered so much by the neglect, he again had recourse to blood letting and was soon relieved of all his phantasms.

The following article is contained in the Edinburgh Journal of Science, conducted by Dr Brewster, who says of the narrator of the case, that, ‘his station in society and as a man of science, would authenticate the minutest particulars in his narrative, and satisfy the most scrupulous reader that the case has been philosophically as well as faithfully described.’ The narrator is in fact the husband of the lady who was the subject of the disease.

‘On the twentysixth of December, 1829, about half past four o’clock in the afternoon, Mrs B. was standing near the fire in the hall, and on the point of going up stairs to dress, when she heard, as she supposed, my voice calling her by name,—Come here, come to me! She imagined that I was calling at the door to have it opened, went to it, and was surprised on opening it to find no one. She returned toward the fire, and again heard the same voice, calling very distinctly and loud,—Come, come here. She then opened two other doors of the same room, but seeing no one, she returned to the fire-place. After a few minutes, she heard the same voice, still calling—‘Come to me, come, come away;’ this time in a loud, plaintive, and somewhat impatient tone. She answered as loudly—‘Where are you? I don’t know where you are’—still imagining that I was somewhere in search of her; but receiving no answer, she shortly went up stairs. On my return to the house about half an hour afterwards, she inquired why I had called to her so often, and where I was; and was of course surprised to hear I had not been near the house at the time.

‘On the 30th of the same month, at about four o’clock, P. M., Mrs B. came down stairs into the drawing room, which she had quitted a few minutes before, and on entering the room, saw me, as she supposed, standing with my back to the fire. She addressed me, asking how it was I had returned so soon. (I had left the house for a walk half an hour before.) She said I looked fixedly at her with a serious and thoughtful expression of countenance, but did not speak. She supposed I was busied in thought, and sat down in an arm-chair near the fire, and within a couple of feet at most of the figure she still saw standing before her. As, however, the eyes still continued to be fixed upon her, after a few moments she said—‘Why don’t you speak—?’ The figure upon this moved off towards the window at the farther end of the room, the eyes still gazing on her, and passed so very close to her in doing so, that she was struck by the circumstance of hearing no step nor sound, nor feeling her clothes brushed against, nor even any agitation of the air. The idea then arose for the first time into her mind, that it was no reality, but a spectral illusion, (being a person of sense and habituated to account rationally for most things, the notion of anything supernatural was out of the question.) She recollected, however, your having mentioned that there was a sort of experimentum crucis, applicable to these cases, by which a genuine ghost may be distinguished from one conjured up by merely natural causes; namely, the pressing the eye in order to produce the effect of seeing double, when, according to your assertion, a true Tartarean ghost may be duplicated as well as everything else; while the morbid idea being, I suppose, an impression on the retina, would or ought to remain single. I am sorry, however, to say, that the opportunity for verifying your theory was unfavorable. Before Mrs B. was able distinctly to double her vision, my figure had retreated to the window and disappeared there. The lady followed, shook the curtains, and tried the windows, being still loth to believe it was not a reality, so distinct and forcible was the impression. Finding, however, that there was no natural means of egress, she became convinced of having seen a spectral apparition, such as are recorded in Dr Hibbert’s work, and consequently felt no alarm or agitation. The appearance lasted four or five minutes. It was bright daylight, and Mrs B. is confident that the apparition was fully as vivid as the reality; and when standing close to her, it concealed, of course, the real objects behind it. Upon being told of this my visible appearance in the spirit, having been only audible a few days before, I was, as you may imagine, more alarmed for the health of the lady than for my own approaching death, or any other fatality the vision might be supposed to forebode. Still both the stories were so very much en regle as ghost stories, the three calls of the plaintive voice, each one louder than the preceding, the fixed eye and mournful expression of the phantom, its noiseless step and spirit-like vanishing, were all so characteristic of the wraith, that I might have been unable to shake off some disagreeable fancies, such as a mind once deeply saturated with the poison of nursery-tales cannot altogether banish, had it not been for a third apparition, at whose visit I myself assisted, a few days afterwards, and which I think is the key-stone of the case, rendering it as complete as could be wished.

‘On the 4th of this month, January, 1830, five days after the last apparition, at about ten o’clock at night, I was sitting in the drawing-room with Mrs B. and in the act of stirring the fire, when she exclaimed, ‘Why, there’s the cat in the room!’ I asked ‘Where?’ She replied, ‘There, close to you.’ ‘Where?’ I repeated. ‘Why, on the rug, to be sure, between yourself and the coal-scuttle.’ I had the poker in my hand, and I pushed in the direction mentioned. ‘Take care,’ she cried out, ‘take care, you are hitting her with the poker.’ I again asked her to point out exactly where she saw the cat. She replied, ‘Why, sitting up there close to your feet, on the rug:—she is looking at me. It is Kitty, come here Kitty.’ There are two cats in the house, one of which went by this name. They are rarely, if ever in the drawing-room. At this time Mrs B. had certainly no idea that the sight of the cat was an illusion. I asked her to touch it. She got up for the purpose, and seemed, too, as if she was pursuing something which moved away. She followed a few steps, and then said,—‘It has gone under that chair.’ I told her it was an illusion. She would not believe it. I lifted up the chair; there was nothing there, nor did Mrs B. see anything more of it. I searched the room all over, and found nothing. There was a dog lying on the hearth, who would have betrayed great uneasiness had a cat been in the room. He was perfectly quiet. In order to be quite certain, I rung the bell and sent for the cats. They were both found in the housekeeper’s room. The most superstitious person could now doubt no longer as to the real character of all these illusory appearances, and the case is so complete, that I hope there will be no renewal of them, symptomatic as they of course are of a disordered state of the body. I am sorry to say Mrs B. as well as myself, forgot to try in time the experimentum crucis on the cat. Mrs B. has naturally a morbidly sensitive imagination, so strongly affecting her corporeal impressions, that the story of any person having severe pain by accident, or otherwise, will occasionally produce acute twinges of pain in the correspondent part in her own person. An account, for instance, of the amputation of an arm, will produce an instantaneous and severe sense of pain in her own arm; and so of other relations. She is subject to talk in her sleep, with great fluency; to repeat poetry very much at length, particularly when unwell, and even cap verses for half an hour together, never failing to quote lines beginning with the final letter of the preceding till her memory is exhausted.
