"I was anxious to see a Mr. H., but was uncertain on what day he would call. On the 19th [July, 1887] I was called out of the office, and, before going out, I put on the door a card having these words on it, 'Will return soon.' I was absent about an hour. On my return I came upstairs, but did not ask the elevator boy if any one had called; nor did he tell me any one had done so. As I came within a short distance of the door, I saw some characters written upon the card I had left, and just below the printed words 'Will return soon,' I stooped down and read, 'Mr. H. has been here, and will return.' As I looked the words faded away. I entered the office, and in a very short time Mr. H. came in. He had left no name or message. He had impressed my face upon his mind very strongly, with the intention of seeing if I would be in any way affected by it, or conscious of his approach." If the fact of accident, intensified by the strained expectation of Mrs. M., cannot be accepted as a satisfactory explanation, it is to be considered that the white surface of the card in this case acted in the same externalising manner as the crystal in the instance given just above. The remotely-operative excitation penetrated the soul unobserved, and was first translated into a conscious image at the moment when the glance at the card favored the formation of hallucinations. Finally a number of other cases are to be mentioned, in which even these suppositions seem insufficient; and for the reason that the events seen were not to happen until some future time. But that which has not yet happened, and which is not to be foreseen in detail, can neither originate in the repositories of memory, nor from the telepathic influence exercised by another person. We should in that case be obliged to accept some hypothesis of clairvoyance in time—_granting of course that all sources of error are excluded_. The reader may judge for himself: "In January last I saw in the Crystal the figure of a man crouching at a small window, and looking into the room from the outside. I could not see his features, which appeared to be muffled, but the Crystal was particularly dark that evening, and the picture being an unpleasant one, I did not persevere. I concluded the vision to be a result of a discussion in my presence of the many stories of burglary with which the newspapers had lately abounded, and reflected with a passing satisfaction, that the only windows in the house divided into four panes as were those of the Crystal-picture, were in the front attic and almost inaccessible. Three days later a fire broke out in that very room, which had to be entered from outside through the window, the face of the fireman being covered with a wet cloth, as a protection from the smoke which rendered access through the door impossible."
