But, it may be asked, how is it possible, amid the bewildering confusion of these records of the past, to find any particular picture when it is wanted? As a matter of fact, the untrained clairvoyant usually cannot do so without some special link to put him en rapport with the subject required. Psychometry is an instance in point, and it is quite probable that our ordinary memory is really only another presentment of the same idea. It seems as though there were a sort of magnetic attachment or affinity between any particle of matter and the record which contains its history—an affinity which enables it to act as a kind of conductor between that record and the faculties of anyone who can read it.

For example, I once brought from Stonehenge a tiny fragment of stone, not larger than a pin's head, and on putting this into an envelope and handing it to a psychometer who had no idea what it was, she at once began to describe that wonderful ruin and the desolate country surrounding it, and then went on to picture vividly what were evidently scenes from its early history, showing that that infinitesimal fragment had been sufficient to put her into communication with the records connected with the spot from which it came. The scenes through which we pass in the course of our life seem to act in the same manner upon the cells of our brain as did the history of Stonehenge upon that particle of stone: they establish a connection with those cells by means of which our mind is put en rapport with that particular portion of the records, and so we "remember" what we have seen.

Even a trained clairvoyant needs some link to enable him to find the record of an event of which he has no previous knowledge. If, for example, he wished to observe the landing of Julius Cæsar on the shores of England, there are several ways in which he might approach the subject. If he happened to have visited the scene of the occurrence, the simplest way would probably be to call up the image of that spot, and then run back through its records until he reached the period desired. If he had not seen the place, he might run back in time to the date of the event, and then search the Channel for a fleet of Roman galleys; or he might examine the records of Roman life at about that period, where he would have no difficulty in identifying so prominent a figure as Cæsar, or in tracing him when found through all his Gallic wars until he set his foot upon British land.

People often enquire as to the aspect of these records—whether they appear near or far away from the eye, whether the figures in them are large or small, whether the pictures follow one another as in a panorama or melt into one another like dissolving views, and so on. One can only reply that their appearance varies to a certain extent according to the conditions under which they are seen. Upon the astral plane the reflection is most often a simple picture, though occasionally the figures seen would be endowed with motion; in this latter case, instead of a mere snapshot a rather longer and more perfect reflection has taken place.

On the mental plane they have two widely different aspects. When the visitor to that plane is not thinking specially of them in any way, the records simply form a background to whatever is going on, just as the reflections in a pier-glass at the end of a room might form a background to the life of the people in it. It must always be borne in mind that under these conditions they are really merely reflections from the ceaseless activity of a great Consciousness upon a far higher plane, and have very much the appearance of an endless succession of the recently invented cinematographe, or living photographs. They do not melt into one another like dissolving views, nor do a series of ordinary pictures follow one another; but the action of the reflected figures constantly goes on, as though one were watching the actors on a distant stage.

But if the trained investigator turns his attention specially to any one scene, or wishes to call it up before him, an extraordinary change at once takes place, for this is the plane of thought, and to think of anything is to bring it instantaneously before you. For example, if a man wills to see the record of that event to which we before referred—the landing of Julius Cæsar—he finds himself in a moment not looking at any picture, but standing on the shore among the legionaries, with the whole scene being enacted around him, precisely in every respect as he would have seen it if he had stood there in the flesh on that autumn morning in the year 55 b.c. Since what he sees is but a reflection, the actors are of course entirely unconscious of him, nor can any effort of his change the course of their action in the smallest degree, except only that he can control the rate at which the drama shall pass before him—can have the events of a whole year rehearsed before his eyes in a single hour, or can at any moment stop the movement altogether, and hold any particular scene in view as a picture as long as he chooses.

In truth he observes not only what he would have seen if he had been there at the time in the flesh, but much more. He hears and understands all that the people say, and he is conscious of all their thoughts and motives; and one of the most interesting of the many possibilities which open up before one who has learnt to read the records is the study of the thought of ages long past—the thought of the cave-men and the lake-dwellers as well as that which ruled the mighty civilisations of Atlantis, of Egypt or Chaldæa. What splendid possibilities open up before the man who is in full possession of this power may easily be imagined. He has before him a field of historical research of most entrancing interest. Not only can he review at his leisure all history with which we are acquainted, correcting as he examines it the many errors and misconceptions which have crept into the accounts handed down to us; he can also range at will over the whole story of the world from its very beginning, watching the slow development of intellect in man, the descent of the Lords of the Flame, and the growth of the mighty civilisations which they founded.

Nor is his study confined to the progress of humanity alone; he has before him, as in a museum, all the strange animal and vegetable forms which occupied the stage in days when the world was young; he can follow all the wonderful geological changes which have taken place, and watch the course of the great cataclysms which have altered the whole face of the earth again and again.

In one especial case an even closer sympathy with the past is possible to the reader of the records. If in the course of his enquiries he has to look upon some scene in which he himself has in a former birth taken part, he may deal with it in two ways; he can either regard it in the usual manner as a spectator (though always, be it remembered, as a spectator whose insight and sympathy are perfect) or he may once more identify himself with that long-dead personality of his—may throw himself back for the time into that life of long ago, and absolutely experience over again the thoughts and the emotions, the pleasures and the pains of a prehistoric past. No wilder and more vivid adventures can be conceived than some of those through which he thus may pass; yet through it all he must never lose hold of the consciousness of his own individuality—must retain the power to return at will to his present personality.

It is often asked how it is possible for an investigator accurately to determine the date of any picture from the far-distant past which he disinters from the records. The fact is that it is sometimes rather tedious work to find an exact date, but the thing can usually be done if it is worth while to spend the time and trouble over it. If we are dealing with Greek or Roman times the simplest method is usually to look into the mind of the most intelligent person present in the picture, and see what date he supposes it to be; or the investigator might watch him writing a letter or other document and observe what date, if any, was included in what was written. When once the Roman or Greek date is thus obtained, to reduce it to our own system of chronology is merely a matter of calculation.
