"So far I have been speaking of cases where the interval between the death and the manifestation was so short as to make the theory of latency possible. The rule adopted in Phantasms of the Living was that this interval must not exceed twelve hours. But we have records of a few cases where this interval has been greatly exceeded, and yet where the fact of the death was still unknown to the percipient at the time of his experience. The theory of latency cannot reasonably be applied to cases where weeks or months divide the vision (or whatever it may be) from the moment of death, which is the latest at which an ordinary[135] telepathically transferred idea could have obtained access to the percipient. And the existence of such cases—so far as it tends to establish the reality of objectively-caused apparitions of the dead—diminishes the objection to conceiving that the appearances, etc., which have very shortly followed death have had a different causation from those which have coincided with or very shortly preceded it. For we shall not be inventing a wholly new class for the former cases, but only provisionally shifting them from one class to another—to a much smaller and much less well-evidenced class, it is true, but one nevertheless for which we have evidence enough to justify us in expecting more."
This, as I conceive, is a sound method of proceeding from ground made secure in Phantasms of the Living—and traversed in my own just previous chapter—to cases closely analogous, save for that little difference in time-relations, that occurrence in the hours which follow, instead of the hours which precede, bodily dissolution, which counts for so much in our insight into cosmic law.[136]
The hypothesis of latency which thus meets us in limine in this inquiry will soon be found inadequate to cover the facts. Yet it will be well to dwell somewhat more fully upon its possible range.
If we examine the proportionate number of apparitions observed at various periods before and after death, we find that they increase very rapidly for the few hours which precede death, and decrease gradually during the hours and days which follow, until after about a year's time they become merely sporadic.
Yet one more point must be touched on, to avoid misconception of the phrase cited above, that "the moment of death is the centre of a cluster of abnormal experiences, of which some precede, while others follow, the death." Gurney, of course, did not mean to assume that the act of death itself was the cause of all these experiences. Those which occur before death may be caused or conditioned, not by the death itself, but by the abnormal state, as of coma, delirium, etc., which preceded the death. This we say because we have many instances where veridical phantasms have coincided with moments of crisis—carriage-accidents and the like—occurring to distant agents, but not followed by death. Accordingly we find that in almost all cases where a phantasm, apparently veridical, has preceded the agent's death, that death was the result of disease and not of accident. To this rule there are very few exceptions. There is a case given in Phantasms of the Living (vol. ii. p. 52), where the phantasm seems on the evidence to have preceded by about half an hour (longitude allowed for) a sudden death by drowning. In this case the percipient was in a Norfolk farmhouse, the drowning man—or agent—was in a storm off the island of Tristan d'Acunha; and we have suggested that an error of clocks or of observation may account for the discrepancy. In another case the death was in a sense a violent one, for it was a suicide; but the morbidly excited state of the girl a few hours before death—when her phantasm was seen—was in itself a state of crisis. But there are also a few recorded cases (none of which were cited in Phantasms of the Living) where a phantasm or double of some person has been observed some days previous to that person's accidental death. The evidence obtained in the Census of Hallucinations, however, tended to show that cases of this sort are too few to suggest even primâ facie a causal connection between the death and the apparition (see Proceedings S.P.R. vol. x. p. 331).
I now proceed briefly to review some of the cases where the interval between death and phantasm has been measurable by minutes or hours.
It is not easy to get definite cases where the interval has been measurable by minutes; for if the percipient is at a distance from the agent we can seldom be sure that the clocks at both places have been correct, and correctly observed; while if he is present with the agent we can rarely be sure that the phantasm observed is more than a mere subjective hallucination. Thus we have several accounts of a rushing sound heard by the watcher of a dying man just after his apparent death, or of some kind of luminosity observed near his person; but this is just the moment when we may suppose some subjective hallucination likely to occur, and if one person's senses alone are affected we cannot allow much evidential weight to the occurrence.[137]
There are some circumstances, however, in which, in spite of the fact that the death is already known, a hallucination occurring shortly afterwards may have some slight evidential value. Thus we have a case where a lady who knew that her sister had died a few hours previously, but who was not herself in any morbidly excited condition, seemed to see some one enter her own dining-room, opening and shutting the door. The percipient (who had never had any other hallucination) was much astonished when she found no one in the dining-room; but it did not till some time afterwards occur to her that the incident could be in any way connected with her recent loss. This reminds us of a case (ii. p. 694[138]) where the Rev. R. M. Hill sees a tall figure rush into the room, which alarms and surprises him, then vanishes before he has time to recognise it. An uncle, a tall man, dies about that moment, and it is remarked that although Mr. Hill knew his uncle to be ill, the anxiety which he may have felt would hardly have given rise to an unrecognised and formidable apparition.
There are cases also where a percipient who has had an apparition of a friend shortly after that friend's known death has had veridical hallucinations at other times, and has never had any hallucination of purely subjective origin. Such a percipient may naturally suppose that his apparition of the departed friend possessed the same veridical character which was common to the rest, although it was not per se evidential, since the fact of the death was already known.
For the present, however, it will be better to return to the cases which are free from this important primâ facie drawback—cases where the percipient was, at any rate, unaware that the death, which the phantasm seemed to indicate, had in fact taken place.
