It seem more and more certain that, as the cells of an immense organism, we are connected with everything that exists by an inextricable network of vibrations, waves, influences, of nameless, numberless and uninterrupted fluids. Nearly always, in nearly all men, everything carried along by these invisible wires falls into the depths of the unconsciousness and passes unperceived, which does not mean that it remains inactive. But sometimes an exceptional circumstance--in the present case, the marvellous sensibility of a first-class medium--suddenly reveals to us, by the vibrations and the undeniable action of one of those wires, the existence of the infinite network. I will not speak here of trails discovered and followed in an almost mediumistic manner, after an object of some sort has been sniffed at. Such stories, though highly probable, as yet lack adequate support. But, within a similar order of ideas, and in a humbler world and one with more modest limits, the dog, for instance, is incessantly surrounded by different scents and smells to which he appears indifferent until his attention is aroused by one or other of these vagrant effluvia, when he extricates it from the hopeless tangle. It would seem as though the trail took life, vibrating like a chord in unison with the animal's wishes, becoming irresistible, and taking it to its goal after innumerable winds and turns.

We see the mysterious network revealed also in "cross-correspondence." Two or three mediums who do not know one another, who are often separated by seas; or continents, who are ignorant of the whereabouts of the one who is to complete their thought, each write a part of a sentence which, as it stands, conveys no meaning whatever. On piecing the fragments together, we perceive that they fit to perfection and acquire an intelligible and obviously premeditated sense. We here find once more the same faculty that permits the medium to detect, among thousands of others, a definite force which was wandering in space. It is true that, in these cases, the spiritualists maintain that the whole experiment is organized and directed by a discarnate intelligence, independent of the mediums, which means to prove its existence and its identity in this manner. Without incontinently rejecting this theory, which is not necessarily indefensible, we will merely remark that, since the faculty is manifested in psychometry without the intervention of the spirits, there can be no sufficient reason for attributing it to them in cross-correspondence.

But in whom does it reside? Is it hidden in ourselves or in the medium? According to Dr. Osty, the clairvoyants are mirrors reflecting the intuitive thought that is latent in each of us. In other words--it is we ourselves who are clairvoyant, and they but reveal to us nor own clairvoyance. Their mission is to stir, to awaken, to galvanize, to illumine the secrets of our subconsciousness and to bring them to the surface of our normal lives. They act upon our inner darkness exactly as, in the photographic dark-room, the developing-bath acts upon the sensitized plate, I am convinced that the theory is accurate as regards intuition and clairvoyance proper, that is to say, in all cases where we are in the medium's presence and more or less directly in touch with him. But is it so in psychometry? Is it we who, unknown to ourselves, know all that the object contains, or is it the medium alone who discovers it in the object itself, independently of the person who produces the object? When, for instance, we receive a letter from a stranger, does this letter, which has absorbed like a sponge the whole life and by choice the subconscious life of the writer, disgorge all that it contained into our subconsciousness? Do we instantly learn all that concerns its author, absolutely as though he were standing before us in the flesh and, above all, with his soul laid bare, though we remain profoundly ignorant of the fact that we have learnt it until the medium's intervention tells us so?

This, if you like, is simply shifting the question. Let it be the medium or myself that discovers the unknown personality in the object or tracks it across time and space: all that we do is to widen the scope of our riddle, while leaving it no less obscure.
