The following passages are quoted from the report by Professor William James, Proceedings S.P.R., vol. vi. pp. 651-59:-
I made Mrs. Piper's acquaintance in the autumn of 1885. My wife's mother, Mrs. Gibbens, had been told of her by a friend, during the previous summer, and never having seen a medium before, had paid her a visit out of curiosity. She returned with the statement that Mrs. P. had given her a long-string of names of members of the family, mostly Christian names, together with facts about the persons mentioned and their relations to each other, the knowledge of which on her part was incomprehensible without supernormal powers. My sister-in-law went the next day, with still better results, as she related them. Amongst other things, the medium had accurately described the circumstances of the writer of a letter which she held against her forehead, after Miss G. had given it to her. The letter was in Italian, and its writer was known to but two persons in this country.
[I may add that on a later occasion my wife and I took another letter from this same person to Mrs. P., who went on to speak of him in a way which identified him unmistakably again. On a third occasion, two years later, my sister-in-law and I being again with Mrs. P., she reverted in her trance to these letters, and then gave us the writer's name, which she said she had not been able to get on the former occasion].
But to revert to the beginning. I remember playing the esprit fort on that occasion before my feminine relatives, and seeking to explain by simple considerations the marvellous character of the facts which they brought back. This did not, however, prevent me from going myself a few days later, in company with my wife, to get a direct personal impression. The names of none of us up to this meeting had been announced to Mrs. P., and Mrs. J. and I were, of course, careful to make no reference to our relatives who had preceded. The medium, however, when entranced, repeated most of the names of "spirits" whom she had announced on the two former occasions and added others. The names came with difficulty, and were only gradually made perfect My wife's father's name of Gibbens was announced first as Niblin, then as Giblin. A child Herman (whom we had lost the previous year) had his name spelt out as Herrin. I think that in no case were both Christian and surnames given on this visit. But the facts predicated of the persons named made it in many instances impossible not to recognise the particular individuals who were talked about. We took particular pains on this occasion to give the Phinuit control no help over his difficulties and to ask no leading questions.
In the light of subsequent experience I believe this not to be the best policy. For it often happens, if you give this trance-personage a name or some small fact for the lack of which he is brought to a standstill, that he will then start off with a copious flow of additional talk, containing in itself an abundance of "tests".
My impression after this first visit was, that Mrs. P. was either possessed of supernormal powers, or knew the members of my wife's family by sight and had by some lucky coincidence become acquainted with such a multitude of their domestic circumstances as to produce the startling impression which she did.
My later knowledge of her sittings and personal acquaintance with her has led me absolutely to reject the latter explanation, and to believe that she has supernormal powers.
I visited her a dozen times that winter, sometimes alone, sometimes with my wife, once in company with the Rev. M. J. Savage. I sent a large number of persons to her, wishing to get the result of as many first sittings as possible. I made appointments myself for most of these people, whose names were in no instance announced to the medium. In the spring of 1886 I published a brief "Report of the Committee on Mediumistic Phenomena" in the Proceedings of the American Society for Psychical Research, of which the following is an extract:-
"I have myself witnessed a dozen of her trances, and have testimony at first hand from twenty-five sitters, all but one of whom were virtually introduced to Mrs. P. by myself. Of five of the sittings we have verbatim stenographic reports. Twelve of the sitters, who in most cases sat singly, got nothing from the medium but unknown names or trivial talk. Four of these were members of the Society, and of their sittings verbatim reports were taken. Fifteen of the sitters were surprised at the communications they received, names and facts being mentioned at the first interview which it seemed improbable should have been known to the medium in a normal way. The probability that she possessed no clue to the sitter's identity was, I believe, in each and all of these fifteen cases, sufficient. But of only one of them is there a stenographic report; so that, unfortunately for the medium, the evidence in her favour is, although more abundant, less exact in quality than some of that which will be counted against her. Of these fifteen sitters, five, all ladies, were blood relatives, and two (I myself being one) were men connected by marriage with the family to which they belonged. Two other connections of this family are included in the twelve who got nothing.
The medium showed a most startling intimacy with this family's affairs, talking of many matters known to no one outside, and which gossip could not possibly have conveyed to her ears. The details would prove nothing to the reader, unless printed in extenso, with full notes by the sitters. It reverts, after all, to personal conviction. My own conviction is not evidence, but it seems fitting to record it. I am persuaded of the medium's honesty, and of the genuineness of her trance; and although at first disposed to think that the 'hits' she made were either lucky coincidences, or the result of knowledge on her part of who the sitter was and of his or her family affairs, I now believe her to be in possession of a power as yet unexplained".
