I have now given a plain, unvarnished statement of the facts from copious notes written at the time the occurrences were taking place, and copied out in full immediately after.

Respecting the cause of these phenomena, the nature of the force to which, to avoid periphrasis, I have ventured to give the name of _Psychic_, and the correlation existing between that and the other forces of nature, it would be wrong to hazard the most vague hypothesis. Indeed, in inquiries connected so intimately with rare physiological and psychological conditions, it is the duty of the inquirer to abstain altogether from framing theories until he has acc.u.mulated a sufficient number of facts to form a substantial basis upon which to reason. In the presence of strange phenomena as yet unexplored and unexplained following each other in such rapid succession, I confess it is difficult to avoid clothing their record in language of a sensational character. But, to be successful, an inquiry of this kind must be undertaken by the philosopher without prejudice and without sentiment. Romantic and superst.i.tious ideas should be entirely banished, and the steps of his investigation should be guided by intellect as cold and pa.s.sionless as the instruments he uses.

Apropos of this Mr. c.o.x wrote to Mr. Crooks:

The results appear to me conclusively to establish the important fact, that there is a force proceeding from the nerve-system capable of imparting motion and weight to solid bodies within the sphere of its influence.

I noticed that the force was exhibited in tremulous pulsations, and not in the form of steady continuous pressure, the indicator rising and falling incessantly throughout the experiment. The fact seems to me of great significance, as tending to confirm the opinion that a.s.signs its source to the nerve organization, and it goes far to establish Dr. Richardson"s important discovery of a nerve atmosphere of various intensity enveloping the human structure.

Your experiments completely confirm the conclusion at which the Investigation Committee of the Dialectical Society arrived, after more than forty meetings for trial and test.

Allow me to add that I can find no evidence even tending to prove that this force is other than a force proceeding from, or directly dependent upon, the human organization, and therefore, like all other forces of nature, wholly within the province of that strictly scientific investigation to which you have been the first to subject it.

Now that it is proved by mechanical tests to be a fact in nature (and if a fact, it is impossible to exaggerate its importance to physiology and the light it must throw upon the obscure laws of life, of mind and the science of medicine) it cannot fail to command the immediate and most earnest examination and discussion by physiologists and by all who take an interest in that knowledge of "man," which has been truly termed "the n.o.blest study of mankind."

To avoid the appearance of any foregone conclusion, I would recommend the adoption for it of some appropriate name, and I venture to suggest that the force be termed the Psychic Force; the persons in whom it is manifested in extraordinary power Psychics; and the science relating to it Psychism as, being a branch of psychology.

The preceding article was published separately by William Crookes in a special brochure which lies before me,[66] and which contains, in addition, the following study, not less curious from the human and anecdotical point of view than from the point of view of the experimenter in physics:

When I first stated in this journal that I was about to investigate the phenomena of so-called Spiritualism, the announcement called forth universal expressions of approval. One said that my "statements deserved respectful consideration"; another expressed "profound satisfaction that the subject was about to be investigated by a man so thoroughly qualified as," etc.; a third was "gratified to learn that the matter is now receiving the attention of cool and clear-headed men of recognized position in science"; a fourth a.s.serted that "no one could doubt Mr. Crookes"s ability to conduct the investigation with rigid philosophical impartiality"; and a fifth was good enough to tell its readers that "if men like Mr. Crookes grapple with the subject, taking nothing for granted until it is proved, we shall soon know how much to believe."

Those remarks, however, were written too hastily. It was taken for granted by the writers that the results of my experiments would be in accordance with their preconceptions. What they really desired was not _the truth_, but an additional witness in favor of their own foregone conclusion. When they found that the facts which that investigation established could not be made to fit those opinions, why--"so much the worse for the facts." They try to creep out of their own confident recommendations of the enquiry by declaring that "Mr. Home is a clever conjurer, who has duped us all." "Mr. Crookes might, with equal propriety, examine the performances of an Indian juggler." "Mr.

Crookes must get better witnesses before he can be believed." "The thing is too absurd to be treated seriously." "It is impossible, and therefore can"t be."[67] "The observers have all been biologized (!) and fancy they saw things occur which really never took place," etc.

These remarks imply a curious oblivion of the very functions which the scientific enquirer has to fulfill. I am scarcely surprised when the objectors say that I have been deceived merely because they are unconvinced without personal investigation, since the same unscientific course of _a priori_ argument has been opposed to all great discoveries. When I am told that what I describe cannot be explained in accordance with preconceived ideas of the laws of nature, the objector really begs the very question at issue, and resorts to a mode of reasoning which brings science to a standstill. The argument runs in a vicious circle: we must not a.s.sert a fact till we know that it is in accordance with the laws of nature, while our only knowledge of the laws of nature must be based on an extensive observation of facts. If a new fact seems to oppose what is called a law of nature, it does not prove the a.s.serted fact to be false, but only that we have not yet ascertained all the laws of nature, or not learned them correctly.

In his opening address before the British a.s.sociation at Edinburgh this year (1871), Sir William Thomson said, "Science is bound by the everlasting law of honor to face fearlessly every problem which can fairly be presented to it." My object in thus placing on record the results of a very remarkable series of experiments is to present such a problem, which, according to Sir William Thomson, "Science is bound by the everlasting law of honor to face fearlessly." It will not do merely to deny its existence, or try to sneer it down. Remember, I hazard no hypothesis or theory whatever; I merely vouch for certain facts, my only object being--the _truth_. Doubt, but do not deny; point out, by the severest criticism, what are considered fallacies in my experimental tests, and suggest more conclusive trials; but do not let us hastily call our senses lying witnesses merely because they testify against preconceptions. I say to my critics, Try the experiments; investigate with care and patience as I have done. If, having examined, you discover imposture or delusion, proclaim it and say how it was done. But, if you find it be a fact, avow it fearlessly, as "by the everlasting law of honor" you are bound to do.

In this part of his work Professor Crookes recalls the experiments of Count de Gasparin and of Thury (detailed above) on the phenomenon of the movement of bodies without contact, a thing proved and demonstrated. We need not recur to that. He adds that the ecteneic force of Professor Thury and psychical force are equivalent terms, and that the nervous atmosphere or fluid of Dr. Benjamin Richardson also belongs here.

Professor Crookes sent his observations to the Royal Society, of which he is a member. The society refused his communications. The evidence goes to show that it had only approved of the gifted chemist"s mixing in heretical and occult researches on consideration of his demonstrating the fallacy of all those prodigies.

[Ill.u.s.tration: FIG. 4.]

[Ill.u.s.tration: FIG. 5.]

Professor Stokes, the secretary, refused to consider the subject at all, or to inscribe even the t.i.tle of the papers in the society"s publications. It was an exact repet.i.tion of what took place at the Academy of Science in Paris in 1853. Professor Crookes scorned these arbitrary and anti-scientific judgments and denials and answered them by publishing the detailed description of his experiments. The following are the essential points of this description:

[Ill.u.s.tration: FIG. 6.]

On trying these experiments for the first time, I thought that actual contact between Mr. Home"s hands and the suspended body whose weight was to be altered was essential to the exhibition of the force; but I found afterwards that this was not a necessary condition, and I therefore arranged my apparatus in the following manner:

The accompanying cuts (Figs. 4, 5, 6) explain the arrangement. Fig. 4 is a general view, and Figs. 5 and 6 show the essential parts more in detail. The reference letters are the same in each ill.u.s.tration. A B is a mahogany board, 36 inches long by 9-1/2 inches wide and 1 inch thick. It is suspended at the end, B, by a spring balance, C, furnished with an automatic register, D. The balance is suspended from a very firm tripod support, E.

The following piece of apparatus is not shown in the figures. To the moving index, O, of the spring balance, a fine steel point is soldered, projecting horizontally outwards. In front of the balance, and firmly fastened to it, is a grooved frame carrying a flat box similar to the dark box of a photographic camera. This box is made to travel by clock-work horizontally in front of the moving index, and it contains a sheet of plate-gla.s.s which has been smoked over a flame.

The projecting steel point impresses a mark on this smoked surface.

If the balance is at rest, and the clock set going, the result is a perfectly straight horizontal line. If the clock is stopped and weights are placed on the end, B, of the board, the result is a vertical line, whose length depends on the weight applied. If, whilst the clock draws the plate along, the weight of the board (or the tension on the balance) varies, the result is a curved line, from which the tension in grains at any moment during the continuance of the experiments can be calculated.

The instrument was capable of registering a diminution of the force of gravitation as well as an increase; registrations of such a diminution were frequently obtained. To avoid complication, however, I will only here refer to results in which an increase of gravitation was experienced.

The end, B, of the board being supported by the spring balance, the end, A, is supported on a wooden strip, F, screwed across its lower side and cut to a knife edge (see Fig. 6). This fulcrum rests on a firm and heavy wooden stand, G H. On the board, exactly over the fulcrum, is placed a large gla.s.s vessel filled with water, I. L is a ma.s.sive iron stand, furnished with an arm and ring, M N, in which rests a hemispherical copper vessel perforated with several holes at the bottom.

The iron stand is two inches from the board, A B, and the arm and copper vessel, M N, are so adjusted that the latter dips into the water 1-1/2 inches, being 5-1/2 inches from the bottom of I, and 2 inches from its circ.u.mference. Shaking or striking the arm, M, or the vessel, N, produces no appreciable mechanical effect on the board, A B, capable of affecting the balance. Dipping the hand to the fullest extent into the water in N, does not produce the least appreciable action on the balance.

As the mechanical transmission of power by Mr. Home is by this means entirely cut off between the copper vessel and the board, A B, it follows that the power of muscular control is thereby completely eliminated.

There was always ample light in the room where the experiments were conducted (my own dining-room) to see all that took place.

Furthermore, I repeated the experiments, not only with Mr. Home, but also with another person possessing similar powers.

[Ill.u.s.tration: FIG. 7.]

_Experiment I._--The apparatus having been properly adjusted before Mr. Home entered the room, he was brought in, and asked to place his fingers in the water in the copper vessel, N. He stood up and dipped the tips of the fingers of his right hand in the water, his other hand and his feet being held. When he said he felt a power, force, or influence, proceeding from his hand, I set the clock going, and almost immediately the end, B, of the board was seen to descend slowly and remain down for about 10 seconds; it then descended a little farther, and afterwards rose to its normal height. It then descended again, rose suddenly, gradually sunk for 17 seconds, and finally rose to its normal height, where it remained till the experiment was concluded.

The lowest point marked on the gla.s.s was equivalent to a direct pull of about 5,000 grains. The accompanying figure 7 is a copy of the curve traced on the gla.s.s.

_Experiment II._--Contact through water having proved to be as effectual as actual mechanical contact, I wished to see if the power or force could affect the weight, either through other portions of the apparatus or through the air. The gla.s.s vessel and iron stand, etc., were therefore removed, as an unnecessary complication, and Mr. Home"s hands were placed on the stand of the apparatus at P (Fig. 4). A gentleman present put his hand on Mr. Home"s hands, and his foot on both Mr. Home"s feet, and I also watched him closely all the time. At the proper moment the clock was again set going; the board descended and rose in an irregular manner, the result being a curved tracing on the gla.s.s, of which Fig. 8 is a copy.

[Ill.u.s.tration: FIG. 8.]

[Ill.u.s.tration: FIG. 9.]

[Ill.u.s.tration: FIG. 10.]

_Experiment III._--Mr. Home was now placed 1 foot from the board, A B, on one side of it. His hands and feet were firmly grasped by a bystander, and another tracing, of which Fig. 9 is a copy, was taken on a moving gla.s.s plate.

_Experiment IV._--(Tried on an occasion when the power was stronger than on the previous occasions.) Mr. Home was now placed three feet from the apparatus, his hands and feet being tightly held. The clock was set going when he gave the word, and the end, B, of the board soon descended, and again rose in an irregular manner, as shown in Fig. 10.

The following series of experiments were tried with more delicate apparatus, and with another person, a lady, Mr. Home being absent. As the lady is non-professional, I do not mention her name. She has, however, consented to meet any scientific men whom I may introduce for purposes of investigation.

[Ill.u.s.tration: FIG. 11.]

[Ill.u.s.tration: FIG. 12.]

A piece of thin parchment, A, Figs. 11 and 12, is stretched tightly across a circular hoop of wood. B C is a light lever turning on D. At the end, B, is a vertical needle-point touching the membrane, A, and at C is another needle-point, projecting horizontally and touching a smoked gla.s.s plate, E F. This gla.s.s plate is drawn along in the direction, H G, by clockwork, K. The end, B, of the lever is weighted so that it shall quickly follow the movements of the centre of the disc, A. These movements are transmitted and recorded on the gla.s.s plate, E F, by means of the lever and needle-point, C. Holes are cut in the side of the hoop to allow a free pa.s.sage of air to the under side of the membrane. The apparatus was well tested beforehand by myself and others, to see that no shaking or jar on the table or support would interfere with the results. The line traced by the point, C, on the smoked gla.s.s was perfectly straight in spite of all our attempts to influence the lever by shaking the stand or stamping on the floor.

[Ill.u.s.tration: FIG. 13.]

_Experiment V._--Without having the object of the instrument explained to her, the lady was brought into the room and asked to place her fingers on the wooden stand at the points, L M, Fig. 11. I then placed my hands over hers to enable me to detect any conscious or unconscious movement on her part. Presently percussive noises were heard on the parchment, resembling the dropping of grains of sand on its surface.

At each percussion a fragment of graphite which I had placed on the membrane was seen to be projected upwards about 1-50th of an inch, and the end, C, of the lever moved slightly up and down. Sometimes the sounds were as rapid as those from an induction-coil, whilst at others they were more than a second apart. Five or six tracings were taken, and in all cases a movement of the end, C, of the lever was seen to have occurred with each vibration of the membrane.

In some cases the lady"s hands were not so near the membrane as L M, but were at N O, Fig. 12.

The accompanying figure 13 gives tracings taken from the plates used on these occasions.

_Experiment VI._--Having met with these results in Mr. Home"s absence, I was anxious to see what action would be produced on the instrument in his presence.

Accordingly I asked him to try, but without explaining the instrument to him.
