After an affirmation so categorical, it is hardly necessary for me to a.s.sure the members of the Dialectical Society that I have acquired, through my own observation, the absolute certainty of the reality of these phenomena....

But although thus compelled, in the absence of conclusive data in regard to _the cause_ of the so-called "Spiritual Phenomena," to refrain from making any positive affirmation in regard to this part of the subject, I may add that while the general a.s.sertion of its spiritual nature, on the part of the occult force which, within the last quarter of a century, has thus manifested itself all over the globe, const.i.tutes a feature of the case which, from its universality, merits the attention of the impartial investigator--the history of the human race, from the earliest ages, furnishes instances of coincidences, previsions and presentiments of warnings experienced in certain critical moments, of apparitions more or less distinctly seen, which are stated, on evidence as trustworthy as that which we possess with regard to any other branch of historical tradition, to have occurred, spontaneously, in the experience of all nations, and which may therefore be held to strengthen the presumption of the possibility of communication between incarnate and discarnate spirits.

I may also add that my own investigations in the fields of philosophy and of modern astronomy have led me, as is well known, to adopt a personal and individual way of regarding the subject of s.p.a.ce and time, the plurality of inhabited worlds, the eternity and ubiquity of the acting forces of the universe, and the indestructibility of souls, as well as of atoms.

The everlastingness of intelligent life ought to be regarded as the result of the harmonious succession of sidereal incarnations.

Our earth being one of the heavenly bodies, a province of planetary existence, and our present life being a phase of our eternal duration, it appears only natural (the _super_natural does not exist) that there should exist a permanent link between the spheres, the bodies, and the souls of the universe, and therefore altogether probable that the existence of this link will be demonstrated, in course of time, by the advance of scientific discovery.

It would be difficult to over-rate the importance of the questions thus brought forward for consideration; and I have seen with lively satisfaction the n.o.ble initiative which, through the formation of your Committee of Inquiry, has been taken by a body of men so justly eminent as the members of the Dialectical Society, in the experimental investigation of these deeply interesting phenomena. I am most happy, therefore, to comply with the tenor of your letter, by sending you the humble tribute of my observations on the subject in question, and thus to have the opportunity of offering to your society the expression of my sincerest good wishes for the speedy elucidation of the mysteries of nature that have not yet been brought within the domain of positive science.

I am, sir, yours faithfully, CAMILLE FLAMMARION, 10, Rue des Moineaux (Palais Royal).

Paris, May 8, 1870.

The foregoing resume of the labors of the Dialectical Society of London shows once more that mediumistic phenomena long ago entered upon the road of scientific experiment. It would seem as if only the wilfully blind could henceforth deny their allegiance.

The results of the studies described also form an answer to the question frequently asked, whether one can undertake similar experiments without knowing a true medium. I reply that, in any meeting of a dozen persons, there will always be one or more mediums. This was proved by the seances of the Count de Gasparin.

The English report also contains (May 25, 1869) a communication from the electrician, Cromwell Varley, declaring that mediumistic phenomena could not be discredited by any observer of good faith, and that, to him, the hypothesis of disembodied spirits is the one that best explains them--just plain, common spirits (as a general thing), like the majority of the citizens of our planet.

The scientific experiments of the Dialectical Society's committee were continued by the "Society for Psychical Research," founded in 1882, the successive presidents of which were Professor Sidgwick, Professor Balfour Stewart, Professor Sidgwick for a second time, Professor William James, Sir William Crookes, Frederick Myers, Sir Oliver Lodge, Professor Richet--all eminent in the departments of science and education. Let me mention here the splendid work of Dr. Hodgson and of Professor Hyslop in the American branch of this society.

The experiments were continued, in a masterly way, by the celebrated chemist, Sir William Crookes, and yielded him the most wondrous results.

My readers will presently realize this.

CHAPTER IX

THE EXPERIMENTS OF SIR WILLIAM CROOKES

The learned chemist, Sir William Crookes, member of the Royal Society of London, the author of several discoveries of the first rank (among which should be placed the discovery, in 1861, of the metal, thallium), and of ingenious experiments on "radiant matter," published his first researches on the subject we are here considering in a review of which he was the editor--the _Quarterly Journal of Science_.

I had the honor of contributing certain astronomical papers to this journal.[62] I will first lay before my readers an extract from Mr.

Crookes's article of the 1st of July, 1871, ent.i.tled "Experimental Investigation of a New Force," in which he describes his studies with Home. I also had occasion myself more than once to hold conversation with this medium.[63]

Twelve months ago in this journal, July 1, 1870, I wrote an article, in which, after expressing in the most emphatic manner my belief in the occurrence, under certain circ.u.mstances, of phenomena inexplicable by any known natural laws, I indicated several tests which men of science had a right to demand before giving credence to the genuineness of these phenomena. Among the tests pointed out were, that a "delicately poised balance should be moved under test conditions;"

and that some exhibition of power equivalent to so many "foot-pounds"

should be "manifested in his laboratory, where the experimentalists could weigh, measure, and submit it to proper tests." I said, too, that I could not promise to enter fully into this subject, owing to the difficulties of obtaining opportunities, and the numerous failures attending the enquiry; moreover, that "the persons in whose presence these phenomena take place are few in number, and opportunities for experimenting with previously arranged apparatus are rarer still."

Opportunities having since offered for pursuing the investigation, I have gladly availed myself of them for applying to these phenomena careful scientific testing experiments, and I have thus arrived at certain definite results which I think it right should be published.

These experiments appear conclusively to establish the existence of a new force, in some unknown manner connected with the human organization, which for convenience may be called the Psychic Force.

Of all the persons endowed with a powerful development of this psychic force, and who have been termed "mediums" upon quite another theory of its origin, Mr. Daniel Dunglas Home is the most remarkable, and it is mainly owing to the many opportunities I have had of carrying on my investigation in his presence that I am enabled to affirm so conclusively the existence of this force. The experiments I have tried have been very numerous, but owing to our imperfect knowledge of the conditions which favor or oppose the manifestations of this force, to the apparently capricious manner in which it is exerted, and to the fact that Mr. Home himself is subject to unaccountable ebbs and flows of the force, it has but seldom happened that a result obtained on one occasion could be subsequently confirmed and tested with apparatus specially contrived for the purpose.

Among the remarkable phenomena which occur under Mr. Home's influence, the most striking, as well as the most easily tested with scientific accuracy, are--(1) the alteration in the weight of bodies, and (2) the playing of tunes upon musical instruments (generally an accordion, for convenience of portability) without direct human intervention, under conditions rendering contact or connection with the keys impossible.

Not until I had witnessed these facts some half-dozen times, and scrutinized them with all the critical ac.u.men I possess, did I become convinced of their objective reality. Still, desiring to place the matter beyond the shadow of doubt, I invited Mr. Home on several occasions to come to my own house, where, in the presence of a few scientific enquirers, these phenomena could be submitted to crucial experiments.

The meetings took place in the evening, in a large room lighted by gas. The apparatus prepared for the purpose of testing the movements of the accordion, consisted of a cage, formed of two wooden hoops, respectively 1 foot 10 inches and 2 feet diameter, connected together by 12 narrow laths, each 1 foot 10 inches long, so as to form a drum-shaped frame, open at the top and bottom; round this 50 yards of insulated copper wire were wound in 24 rounds, each being rather less than an inch from its neighbor. The horizontal strands of wire were then netted together firmly with string, so as to form meshes rather less than 2 inches long by 1 inch high. The height of this cage was such that it would just slip under my dining-table, but be too close to the top to allow of the hand being introduced into the interior, or to admit of a foot being pushed underneath it. In another room were two Grove's cells, wires being led from them into the dining-room for connection, if desirable, with the wire surrounding the cage.

The accordion was a new one, having been purchased by myself for the purpose of these experiments at Wheatstone's, in Conduit Street. Mr.

Home had neither handled nor seen the instrument before the commencement of the test experiments.

In another part of the room an apparatus was fitted up for experimenting on the alteration in the weight of a body. It consisted of a mahogany board, 36 inches long by 9-1/2 inches wide and 1 inch thick. At each end a strip of mahogany 1-1/2 inches wide was screwed on, forming feet. One end of the board rested on a firm table, whilst the other end was supported by a spring balance hanging from a substantial tripod stand. The balance was fitted with a self-registering index, in such a manner that it would record the maximum weight indicated by the pointer. The apparatus was adjusted so that the mahogany board was horizontal, its foot resting flat on the support. In this position its weight was 3 lbs., as marked by the pointer of the balance.

[Ill.u.s.tration: PLATE XII. CAGE OF COPPER WIRE, ELECTRICALLY CHARGED, USED BY PROFESSOR CROOKES IN THE HOME ACCORDION EXPERIMENT.]

Before Mr. Home entered the room the apparatus had been arranged in position, and he had not even the object of some parts of it explained before sitting down. It may, perhaps, be worth while to add, for the purpose of antic.i.p.ating some critical remarks which are likely to be made, that in the afternoon I called for Mr. Home at his apartments, and when there he suggested that, as he had to change his dress, perhaps I should not object to continue our conversation in his bedroom. I am, therefore, enabled to state positively, that no machinery, apparatus, or contrivance of any sort was secreted about his person.

The investigators present on the test occasion were an eminent physicist, high in the ranks of the Royal Society,[64] a well-known Serjeant-at-Law;[65] my brother; and my chemical a.s.sistant.

Mr. Home sat in a low easy-chair at the side of the table. In front of him under the table was the aforesaid cage, one of his legs being on each side of it. I sat close to him on his left, and another observer sat close to him on his right, the rest of the party being seated at convenient distances round the table.

For the greater part of the evening, particularly when anything of importance was proceeding, the observers on each side of Mr. Home kept their feet respectively on his feet, so as to be able to detect his slightest movement.

The temperature of the room varied from 68 degrees to 70 degrees F.

Mr. Home took the accordion between the thumb and middle finger of one hand at the opposite end to the keys (see Pl. XII A) (to save repet.i.tion this will be subsequently called "in the usual manner").

Having previously opened the ba.s.s key myself, and the cage being drawn from under the table so as just to allow the accordion to be pushed in with its keys downwards, it was pushed back as close as Mr. Home's arm would permit, but without hiding his hand from those next to him (Pl. XII, Cut B). Very soon the accordion was seen by those on each side to be waving about in a somewhat curious manner; then sounds came from it, and finally several notes were played in succession. Whilst this was going on, my a.s.sistant went under the table, and reported that the accordion was expanding and contracting; at the same time it was seen that the hand of Mr. Home by which it was held was quite still, his other hand resting on the table.

Presently the accordion was seen by those on either side of Mr. Home to move about, oscillating and going round and round the cage, and playing at the same time. Dr. A. B. now looked under the table, and said that Mr. Home's hand appeared quite still whilst the accordion was moving about emitting distinct sounds.

Mr. Home still holding the accordion in the usual manner in the cage, his feet being held by those next him, and his other hand resting on the table, we heard distinct and separate notes sounded in succession, and then a simple air was played. As such a result could only have been produced by the various keys of the instrument being acted upon in harmonious succession, this was considered by those present to be a crucial experiment.

But the sequel was still more striking, for Mr. Home then removed his hand altogether from the accordion, taking it quite out of the cage, and placed it in the hand of the person next to him. The instrument then continued to play, no person touching it and no hand being near it.

I was now desirous of trying what would be the effect of pa.s.sing the battery current round the insulated wire of the cage, and my a.s.sistant accordingly made the connection with the wires from the two Grove's cells. Mr. Home again held the instrument inside the cage in the same manner as before, when it immediately sounded and moved about vigorously. But whether the electric current pa.s.sing round the cage a.s.sisted the manifestation of force inside, it is impossible to say.

After this experiment, the accordion, which he kept holding in one hand, then commenced to play, at first chords and runs, and afterwards a well-known sweet and plaintive melody, which was executed perfectly in a very beautiful manner. Whilst this tune was being played I grasped Mr. Home's arm, below the elbow, and gently slid my hand down it until I touched the top of the accordion. He was not moving a muscle. His other hand was on the table, visible to all, and his feet were under the feet of those next to him.

Having met with such striking results in the experiments with the accordion in the cage, we turned to the balance apparatus already described. Mr. Home placed the tips of his fingers lightly on the extreme end of the mahogany board, which was resting on the support, whilst Dr. A. B. and myself sat, one on each side of it, watching for any effect which might be produced. Almost immediately the pointer of the balance was seen to descend. After a few seconds it rose again.

This movement was repeated several times, as if by successive waves of the psychic force. The end of the board was observed to oscillate slowly up and down during the experiment.

Mr. Home now of his own accord took a small hand-bell and a little card match-box, which happened to be near, and placed one under each hand, to satisfy us, as he said, that he was not producing the downward pressure (see Fig. 3). The very slow oscillation of the spring balance became more marked, and Dr. A. B., watching the index, said that he saw it descend to 6-1/2 lbs. The normal weight of the board as so suspended being 3 lbs., the additional downward pull was therefore 3-1/2 lbs. On looking immediately afterwards at the automatic register, we saw that the index had at one time descended as low as 9 lbs., showing a maximum pull of 6 lbs. upon a board whose normal weight was 3 lbs.

In order to see whether it was possible to produce much effect on the spring balance by pressure at the place where Mr. Home's fingers had been, I stepped upon the table and stood on one foot at the end of the board. Dr. A. B., who was observing the index of the balance, said that the whole weight of my body (140 lbs.) so applied only sunk the index 1-1/2 lbs., or 2 lbs. when I shook it. Mr. Home had been sitting in a low easy-chair, and could not, therefore, had he tried his utmost, have exerted any material influence on these results. I need scarcely add that his feet as well as his hands were closely guarded by all in the room.

This experiment appears to me more striking, if possible, than the one with the accordion. As will be seen on referring to the cut (Fig. 3), the board was arranged perfectly horizontally, and it was particularly noticed that Mr. Home's fingers were not at any time advanced more than 1-1/2 inches from the extreme end, as shown by a pencil-mark, which, with Dr. A. B.'s acquiescence, I made at the time. Now, the wooden foot being also 1-1/2 inches wide, and resting flat on the table, it is evident that no amount of pressure exerted within this s.p.a.ce of 1-1/2 inches could produce any action on the balance. Again, it is also evident that when the end farthest from Mr. Home sank, the board would turn on the farther edge of this foot as on a fulcrum.

[Ill.u.s.tration: FIG. 3.]

The arrangement was consequently that of a see-saw, 36 inches in length, the fulcrum being 1-1/2 inches from one end; were he, therefore, to have exerted a downward pressure, it would have been in opposition to the force which was causing the other end of the board to move down.

The slight downward pressure shown by the balance when I stood on the board was owing probably to my foot extending beyond this fulcrum.
