Enlisting the services of some four hundred "collectors," the committee instructed each of these to address to twenty-five adults, selected at random, the query, "Have you ever, when believing yourself to be completely awake, had a vivid impression of seeing or being touched by a living being or inanimate object, or of hearing a voice; which impression, so far as you could discover, was not due to any external physical cause?" In all, seventeen thousand people were thus questioned, and almost ten per cent. of the answers received proved to be in the affirmative. More than this, it appeared that out of a total of three hundred and fifty recognized apparitions of living persons, no fewer than sixty-five were "death coincidences," in which the hallucinatory experience occurred within from one hour to twelve hours after the death of the person seen.

Sifting these death coincidences carefully, the committee for various reasons rejected more than half, and at the same time raised the total of recognized apparitions of living persons from three hundred and fifty to thirteen hundred. This was done in order to make generous allowance for the number of such apparitions forgotten by those to whom the question had been put, investigation showing that the great majority of hallucinations reported were given as of comparatively recent occurrence, and that there was a rapid decrease as the years of occurrence became more remote.

As a final result, therefore, the committee found about thirty death coincidences out of thirteen hundred cases, or a proportion of one in forty-three. Computing from the average annual death-rate for England and Wales, it was calculated that the probability that any one person would die on a given day was about one in nineteen thousand; in other words, out of every nineteen thousand apparitions of living persons, there should occur, by chance alone, one death coincidence. The actual proportion, however, as established by the inquiry, was equivalent to about four hundred and forty in nineteen thousand, or four hundred and forty times the most probable number, and this when the apparitions reported were considered merely collectively as having been seen at any time within twelve hours after death. Not a few, as a matter of fact, were reported as having been seen within one hour after death, and for these the improbability of occurrence by chance alone was manifestly twelve times four hundred and forty. In view of these considerations the committee felt warranted in declaring that "between deaths and apparitions of dying persons a connection exists which is not due to chance."[J]

Had Lord Brougham lived to study the statistics of this remarkable census of hallucinations, he might have formed a higher opinion of his ghost; but he would also have been in a better position to deny its supernatural attributes. For, if the Society for Psychical Research has made it impossible to doubt the existence of such ghosts as that which he beheld during his travels in Sweden, it has likewise made discoveries which afford a really substantial reason for asserting that they no more hail from the world beyond than do ghosts that are unmistakably the creations of fancy or fraud. This results from the society's investigations of thought transference or telepathy, to use the term now commonly employed.

At an early stage of the experiments undertaken to determine the possibility of transmitting thought from mind to mind without the intervention of any known means of communication, it was found that when success attended the efforts of the experimenters the telepathic message was frequently received not in the form of pure thought but as a hallucinatory image; and what is still more important in the present connection, it was further found possible so to produce not merely images of cards, flowers, books, and other inanimate objects, but also images of living persons.

Thus, as chronicled with corroborative evidence in the society's "Proceedings," an English clergyman named Godfrey telepathically caused a distant friend to see an apparition of him one night; the same result was achieved by a Mr. Sinclair of New Jersey, who, during a visit to New York, succeeded in projecting a phantasm of himself which was clearly seen by his wife in Lakewood; and similarly a Mr. Kirk, while seated in his London office, paid a telepathic visit to the home of a young woman, who saw him as distinctly as though he had gone there in the flesh. In all of these, as in other cases recorded by the society, the persons to whom the apparitions were vouchsafed had no idea that any experiment of the kind was being attempted.

Indeed, there is on record an apparently well authenticated instance of the experimental production of an apparition not of the living but of the dead. This occurred in Germany many years ago, when a certain Herr Wesermann undertook to "will" a military friend into dreaming of a woman who had long been dead. The sequel may be related in Herr Wesermann's own words:

"A lady, who had been dead five years, was to appear to Lieutenant N. in a dream at 10.30 P.M., and incite him to good deeds. At half-past ten, contrary to expectation, Herr N. had not gone to bed but was discussing the French campaign with his friend Lieutenant S. in the ante-room. Suddenly the door of the room opened, the lady entered dressed in white, with a black kerchief and uncovered head, greeted S. with her hand three times in a friendly manner; then turned to N., nodded to him, and returned again through the doorway.

"As this story, related to me by Lieutenant N., seemed to be too remarkable from a psychological point of view for the truth of it not to be duly established, I wrote to Lieutenant S., who was living six miles away, and asked him to give me his account of it. He sent me the following reply:

"'On the thirteenth of March, 1817, Herr N. came to pay me a visit at my lodgings about a league from A——. He stayed the night with me. After supper, and when we were both undressed, I was sitting on my bed and Herr N. was standing by the door of the next room on the point also of going to bed. This was about half-past ten. We were speaking partly about indifferent subjects and partly about the events of the French campaign. Suddenly the door of the kitchen opened without a sound, and a lady entered, very pale, taller than Herr N., about five feet four inches in height, strong and broad of figure, dressed in white, but with a large black kerchief which reached to below the waist.
