Again, we cannot tell how long the spirit may continue the effort, or, so to say, renew the experiment. In a case recorded in _Proceedings_ S.P.R., vol. x. p. 378, the compact is fulfilled after a space of five years. In another case,[147] there had been no formal compact; but there is an attempt to express gratitude on an anniversary of death; and this implies the same kind of mindful effort as the fulfilment of a definite promise. I have now traced certain _post-mortem_ manifestations which reveal a recollection of events known at death, and also a persistence of purpose in carrying out intentions formed before death. In this next group I shall trace the knowledge of the departed a little further, and shall discuss some cases where they appear cognisant of the aspect of their bodies after death, or of the scenes in which those bodies are temporarily deposited or finally laid. Such knowledge may appear trivial,--unworthy the attention of spirits transported into a higher world. But it is in accordance with the view of a gradual transference of interests and perceptions,--a period of intermediate confusion, such as may follow especially upon a death of a sudden or violent kind, or perhaps upon a death which interrupts very strong affections. Thus we have already (Appendix VII. B) encountered one striking case of this type,--the _scratch on the cheek_, perceived by the departed daughter, as we may conjecture, by reason of the close sympathy which united her to the mother who was caring for her remains. There are also two cases closely resembling each other, though from percipients in widely different parts of the world, where a clairvoyant vision seems to be presented of a tranquil death-chamber. In that of Mr. Hector of Valencia, South Australia (see _Phantasms of the Living_, vol. i. p. 353), the percipient sees in a dream his father dying in the room he usually occupied, with a candle burning on a chair by his bed; and the father is found dead in the morning, with a candle by his bedside in the position seen in the dream. There is not, however, in this case any sure indication that the dead or dying person was cognisant of his own body's aspect or surroundings. There may have been a clairvoyant excursion on the percipient's part, evoked by some impulse from the agent which did not itself develop into distinctness.[148]
