It has recently been announced that Thomas A. Edison is at work upon a device to enable spirits to communicate with the living, if there really are spirits seeking to do this. It is Edison's idea that spirits may inhabit some kind of infinitely rarefied astral body, and he proposes to manufacture an instrument which is sensitive to an impression many millions of times fainter than anything the human body can feel. This should make it easier for the spirits, and should constitute a fairer test, possibly a decisive one. When that machine is perfected and put to work by scientific men, I wish to suggest a few tests which will convince me that there really are spirits, and that the results are not to be explained by telepathy.
First, assuming that the spirits live forever, there are some useful things which were known to the people of ancient time, and are not known to anyone living now. For example, let one of the Egyptian craftsmen come forward and tell us the secret of their glass-staining, which I understand is now a lost art. And then Sophocles, as I have already suggested, will tell us where we can find his lost dramas; or if he doesn't know where any copies are buried, let him find in the spirit world some scribe or librarian or book-lover who can give us this priceless information. All over the ancient lands are buried and forgotten cities, and in those cities are papyrus scrolls and graven tablets and bricks. Infinite stores of knowledge are thus concealed from us; and how simple for the ancient ones who possess this information to make it known to us, and so to convince us of their reality!
Or, again, supposing that spirits are not immortal, but that they slowly fade from life as do their bodies. Suppose that a Raymond Lodge or other recently dead soldier wishes to communicate with his father and to convince his father that it is really an independent being, and not simply a part of the father's subconscious mind--let him try something like this. Let the father write six brief notes, and put them in six envelopes all alike, and shuffle them up and put them in a hat and draw out one of them. Now, assuming that the experimenter is honest, there is no living human being who knows the contents of that envelope, and if the medium is dipping into the subconscious mind of the experimenter, the chances are one in six of the right note being hit upon. Assuming that spirits may not be able to get inside an envelope and read a folded letter, there is no objection to the experimenter, provided he is honest, and provided there are no mirrors or other tricks, holding the envelope behind his back, and tearing it open, and spreading it out for the convenience of the spirit. And now, if the spirit can read that letter correctly every time, we shall be fairly certain that whatever force

we are dealing with, it is not the subconscious mind of the experimenter.
Or, let us take another test. Let us have a roulette wheel in a covered box, or hidden away so that no one but the spirit can see it. We spin the wheel, and any one of the habitues of Monte Carlo can figure out the chance of the little ball dropping into any particular number. If now the spirit can tell us each time where we shall find the ball, we shall know that we are dealing with knowledge which does not exist either in the conscious or the subconscious mind of any living human being.
Among the things that "spirits" have been accustomed to do, since the days when they first made their appearance with the Fox sisters in America, are the lifting of tables and the ringing of bells and the assuming of visible forms. These are what is known as "materializations," and when I was a boy, and used to hear people talking about these things, there was always one test required: let the materializations manifest themselves upon recording instruments scientifically devised; let photographs be taken of them, let them
be weighed and measured, and so on. Well, time has moved forward, and these tests have been met, and it appears that "materializations" are facts--although it is still as uncertain as ever what they are materializations of. An English scientist, Professor Crawford, has published a book entitled "The Reality of Psychic Phenomena," in which he tells the results of many years of testing materializations by the strictest scientific methods. When the medium "levitates" a table--that is, causes it to go up in the air without physical contact--it appears that her own weight increases by exactly the weight of the table. When she exerts any force, which apparently
she can do at a distance, the recording instruments show the exact counter-force in her own body.
The results of these investigations are calculated at first to take your breath away. It begins to appear that the theosophists may be right, and that we may have one or more "astral" bodies within or coincident with the physical body; and that under the trance conditions we mold and make over this "astral" body in accordance with our imaginations, precisely as a sculptor molds the clay. At any rate, our subconsciousness has the power to project from it masses of substance, and to cause these to take all kinds of forms, for example, human faces, which have been photographed innumerable times. Or the body can shoot out long rods or snaky projections, which lift tables, and exert force which has been recorded upon pressure instruments and weighed by scales.
As I write, a friend lends me a fifteen-dollar volume, a translation just published of an elaborate work by Baron von Schrenck-Notz- ing, a physician of Munich, giving minute details of four years' experiments in this field. So rigid was this investigator in his efforts to exclude fraud, that not merely was the medium stripped and sewed up in black tights, but the "cabinet" in which she sat was a big
sack of black cloth, everywhere sewed tight by machine. Every crevice of the medium's body was searched before and after the tests, and every inch of the "cabinet" gone over. The investigators sat within a couple of feet of the medium, and would draw back the curtains, and while holding her hands and her feet, would watch great masses of filmy gray and white stuff exude from the medium's mouth, from her armpits and breasts and sides. This would happen in red light of a hundred candle power, by which print could be easily read; and the medium would herself illuminate the phenomena with a red electric torch. The investigators would be privileged to examine these "phantom" forms, to touch them gently, and be touched by them--soft and slimy, like the tongue of an animal; but sometimes the things would misbehave, and strike them in the eye, hurting them.
The medium, a young French girl living in the home of the wife of a well-known French playwright, had begun with spiritualist ideas, but came to take a matter-of-fact attitude to what happened, and in her trances would labor to mold these emanations into hands or faces, as requested by those present. She finally succeeded in allowing them to separate the soft mucous stuff from her body, and keep it for chemical and bacteriological examination. All this time she would be surrounded by a battery of cameras, nine at once, some of them inside the cabinet; and when the desired emanation was in sight, all these cameras would be set off by flash-light, and in the book you have over two hundred such photographs, showing faces and hands from every point of view. There are even moving-pictures, showing the material coming out of her mouth and going back!
It is evident that we have here a whole universe of unexplored phenomena; and it seems that many of the oldtime superstitions which were dumped overboard have now to be dragged back into the boat and examined in the light of new knowledge. What could smack more of magic and fraud than crystal-gazing? Yet it appears that the subconsciousness has power to project an image of its hidden memories into a crystal ball, where it may be plainly seen. We find so well-recognized an authority as Dr. Morton Prince using this method to enable one of the many Miss Beauchamps to recall incidents in her previous life which were otherwise entirely lost
to her. Likewise this exploration of the disintegration of personality enables us to watch in the making all the phenomena of trance and ecstasy which have had so much to do with the making of
