Is he a victim of hallucination? It is possible; but then how are we to explain the fragment of truth which exists in his hallucination? I am well aware that impersonal memory is an inexhaustible source of knowledge, quite unknown to the normal personality; but there are cases, where the hypothesis of hypermnesia is scarcely acceptable. Here is an example. The medium, of whom I spoke a little while ago, has several times had the impression that a deceased person unknown to him, but known to me, entered his bedroom. The apparition was preceded by a noise of approaching footsteps, the door appeared to open, and the form entered. The form sat down at the foot of the bed, caressed the medium’s arm, and took his hand. The sensitive was alarmed at these visions, which he looks upon as hallucinations, and does his best to rid himself of. At the end of three or four visits the form ceased to show itself, to my great regret, for I had therein the occasion of making an observation of the highest interest. Unfortunately, I had not sufficient influence over this remarkable sensitive, to induce him to lend a hand to the development of this phenomenon. The person reputed to appear had a very characteristic walk, and it would be sufficient for me to describe it, for those who knew the man to recognise him at once; the vision had the same characteristic walk. Again, my friend wore whiskers. But the vision wore a full short beard, a detail which the doctor who attended him in his last illness verified; my friend did not shave towards the end of his life. I was not aware of this. The medium, living in the same town, could have known the man; but if, contrary to his assertions, he had known him, how could he have seen him wearing a beard such as he never used to wear? Interesting detail! since the apparition, purporting to be my friend, wore a beard just as my friend had worn, not in his lifetime, but at the time of his death. Further, the apparition appeared to manifest a desire to speak. It tried to reassure the alarmed medium; but the latter always got up and turned on the light, before the phantom had time to speak. Now at that moment, an event was brewing, of which I would have been thankful to have been warned. The incident occurred, and the apparition was not seen again. This is an _ensemble_ of facts of a nature to arouse attention. I have not been able to submit the case to thorough analysis, and I give it with reserve. It is the nearest approach to classical spiritism, which I have personally met with, but to me it does not seem to be convincing under the conditions in which I observed it; for the incident I refer to could easily have been foreseen by the medium.
