What, then, has happened to strengthen the case of the believers in ghosts, clairvoyance, thought-transference, sensory automatism, in, say, the last quarter of a century? What new evidence exists which would make the mid-Victorian scientific men reconsider their position? Suppose Faraday and Huxley, Spencer and Tyndall, were alive to-day, would they see reason to alter their opinions? I remember once--and I now give it as typical--overhearing a psychical experience. It was in a first-class compartment on a train coming from Wimbledon. One of my fellow-passengers, an intelligent, well-spoken man of about thirty-five, was relating to three friends the following extraordinary story. As nearly as I can recollect, I give the narrator's own words:-- "One week ago last Tuesday, at eleven o'clock at night, my wife, who had just retired to bed upstairs, called out to me: 'Arthur! Arthur!' in a tone of alarm. I sprang up and ran upstairs to see what was the matter. The servants had all gone to bed. 'Arthur,' said my wife, 'I've just seen mother,' and she began to cry. 'Why,' I said, 'your mother's at Scarborough.' 'I know,' she said; 'but she appeared before me just there' (pointing to the foot of the bed) 'two minutes ago as plainly as you do.' Well, the next morning there was a telegram on the breakfast-table: 'Mother, died at eleven last night.' Now, how do you account for it?" There was silence for a full minute. "A wonderful coincidence. Your wife's hallucination coincided with her mother's death!" Another occupant of the carriage caught up the word: "Yes, coincidence. A thing which mightn't happen once in a million years." Nobody else ventured a remark. Yet they seemed unconvinced. There was no one to tell them--even I did not know then--that these "coincidences" were constantly happening, every year, perhaps every month; that an intelligent body of men--the Society for Psychical Research--has made a census of such hallucinations, all apparently well attested; that newspapers devoted to occult matters constantly record these things; that volumes--monthly, weekly, almost--fairly pour from the press detailing, expounding, dissecting, elaborating such evidence; that the theory of coincidence has already been rejected by many men of the first rank of science; and that official science itself is reluctantly reconsidering its position in more than one direction.
