It is very difficult to fathom the nature of this intuition. Does it relate to events partly or wholly realized, but still in a latent state and perceived before the knowledge of them reaches us through the normal channels of the mind or brain? Does our ever-watchful instinct of self-preservation notice causes or traces which escape our ever-inattentive and slumbering reason? Are we to believe in a sort of autosuggestion that induces us to realize things which we have been foretold or of which we have had presentiments? This is not the place to examine so complex a problem, which brings us into contact with all the mysteries of subconsciousness and the preexistence of the future. There remains another point to which it is well to draw attention in order to avoid misunderstanding and disappointment. Experience shows us that the medium perceives the person in question quite clearly, in his present and usual state, but not necessarily in the exact accidental state of the moment. She will tell you, for instance, that she sees him ailing slightly, lying in a deck-chair in a garden of such and such a kind, surrounded by certain flowers and petting a dog of a certain size and breed. On enquiring, you will find that all these details are strictly correct, with one exception, that at that precise moment this person, who ordinarily spends his time in the garden, was inside his house or calling on a neighbour. Mistakes in time therefore are comparatively frequent and simultaneity between action and vision comparatively rare. In short, the habitual often masks the accidental action. This, I insist, is a point of which we must not lose sight, lest we ask of psychometry more than it is obviously able to give us. 2 Having said so much, is it open to us, amid all the mental anguish and suffering which this terrible war has engendered, without profaning the sorrow of our fellow-men and women, to give to those who are in mortal fear as to the fate of some one whom they love the hope of finding, among those extrahuman phenomena which have been unjustly and falsely disparaged, a consoling gleam of light that shall not be a mere mockery or delusion? I venture to declare--and I am doing so not thoughtlessly, but after studying the problem with the conscientious attention which it demands and after personally making a number of experiments or causing them to be made under my supervision--I venture to declare, without for a moment losing sight of the respect due to grief, that we possess here, in these indisputable cases where no normal mode of communication is possible, a strange but real and serious source of information and comfort. I could mention a large number of tests that have been made, so to speak, before my eyes by absolutely trustworthy relatives or friends.
