‘I may also add that, though to-day four years after these visions occurred, Madame X. has become one of my friends, at that moment, October 1900, our acquaintanceship dated from a few months only; and, at Madame X.’s own request, in order to avoid hints and suggestions, I abstained from ever speaking with her on anything save vague, general topics. Madame X., at this time, lived a secluded, retired life in a convent, seldom going out and receiving no visitors. She was, moreover, almost an entire stranger to Paris, having arrived there only a short time before I made her acquaintance. If Madame X. spoke of any one of my deceased friends to-day, it would be impossible for me to affirm positively that I had never pronounced that name in her presence; but, thanks to the great care I took at that moment to avoid all manner of confidences whatsoever, continually seconded in my efforts by Madame X. herself, I can certify that the name of Antoine B. had not been pronounced up to the month of October 1900. ‘Therefore my stupefaction was indeed great, when I discovered in Madame X.’s letters so many precise and correct data, though mixed up with occasional errors. And when I speak of precise and correct data, I do not mean data, traces of which may have been left in printed matter. I speak of private, unpublished facts, facts known only to me or to his wife. Notwithstanding this, however, I was blind to the truth. And I sought to explain away these phenomena of lucidity, by an apparently rational explanation. ‘Here is the fable I invented, for I think it may be useful to acquaint the reader with my hesitations, and the manner in which I tried to explain these facts. First of all, I supposed that Fontainebleau was a mistake, since, as far as I knew, Antoine B. did not go to Fontainebleau in 1883. At the same time, I thought I remembered he had been a pupil at the School of Artillery at Fontainebleau in 1874. But, I asked myself, why should Madame X. speak about Antoine B., whose name I was and am certain never to have pronounced in her presence? I found, or rather I thought I had found, the explanation. In the month of September 1900, Antoine B.’s daughter Madeleine, the wife of Jacques S., died, and one or two newspapers mentioned this sad and premature death. Now, I supposed that Madame X. had unconsciously glanced over one of these newspapers, that Antoine B.’s name had appeared therein with his biography more or less fully traced, our relations mentioned [he had been director with me of the _Revue Scientifique_,] and reference made to his term at the School of Application at Fontainebleau. That was my fable. ‘It is true there were several other facts awaiting explanation; but I did not let them hinder me,—so dazed are we by the fear of meeting with the truth just where it really is, when we find ourselves in the presence of facts, with which force of habit has not yet rendered us familiar.
