He thinks these ‘coincidences’ were apt to happen because the matters from which they sprang were matters which many of the foremost minds in the world were busy thinking about. But perhaps one man in each case did the telegraphing to the others. The aberrations which gave Leverrier the idea that there must be a planet of such and such mass and such and such an orbit hidden from sight out yonder in the remote abysses of space were not new; they had been noticed by astronomers for generations. Then why should it happen to occur to three people, widely separated—Leverrier, Mrs. Somerville, and Adams—to suddenly go to worrying about those aberrations all at the same time, and set themselves to work to find out what caused them, and to measure and weigh an invisible planet, and calculate its orbit, and hunt it down and catch it?—a strange project which nobody but they had ever thought of before. If one astronomer had invented that odd and happy project fifty years before, don’t you think he would have telegraphed it to several others without knowing it? But now I come to a puzzler. How is it that _inanimate_ objects are able to affect the mind? They seem to do that. However, I wish to throw in a parenthesis first—just a reference to a thing everybody is familiar with—the experience of receiving a clear and particular _answer_ to your telegram before your telegram has reached the sender of the answer. That is a case where your telegram has gone straight from your brain to the man it was meant for, far outstripping the wire’s slow electricity, and it is an exercise of mental telegraphy which is as common as dining. To return to the influence of inanimate things. In the cases of non-professional clairvoyance examined by the Psychical Society the clairvoyant has usually been blindfolded, then some object which has been touched or worn by a person is placed in his hand; the clairvoyant immediately describes that person, and goes on and gives a history of some event with which the text object has been connected. If the inanimate object is able to affect and inform the clairvoyant’s mind, maybe it can do the same when it is working in the interest of mental telegraphy. Once a lady in the West wrote me that her son was coming to New York to remain three weeks, and would pay me a visit if invited, and she gave me his address. I mislaid the letter, and forgot all about the matter till the three weeks were about up. Then a sudden and fiery irruption of remorse burst up in my brain that illuminated all the region round about, and I sat down at once and wrote to the lady and asked for that lost address. But, upon reflection, I judged that the stirring up of my recollection had not been an accident, so I added a postscript to say, never mind, I should get a letter from her son before night. And I did get it; for the letter was already in the town, although not delivered yet. It had influenced me somehow. I have had so
