CHAPTER X.

SPECTRES—THE GHOST ILLUSION.

WE close our account of the wonders of optics by a description of the

ghost illusion, which has been exhibited with such great success by M.

Robin, the well-known French conjurer, Mr. Pepper, the enterprising

manager of the Royal Polytechnic Institution, and several others. Before

doing so, however, we will say a few words on those unpleasant

visitations known as spectres, to which some people are liable, either

through an over-worked brain or some organic disease.

The peculiar appearances known as spectres in optics are certain

illusions of vision in which an object is apparently presented to the

view which does not really exist. In such cases either the brain, the

retina, or the optic nerve are unnaturally excited, and made sensitive

to an appearance that, physically speaking, does not exist. There is

such a close connexion between the senses and the mind, that we

continually, and without knowing it, transfer to the physical world that

which belongs to the domain of thought. A picture which has struck us

during the day will reappear to us at night during sleep, with every

detail perfect, or possibly under a form modified by the capricious

wanderings of our thoughts. A sudden fright may sometimes be the cause

of optical illusions which will pursue us unceasingly. Fear, despair,

passion, ambition, and other violent mental phases, are capable of

evoking images closely connected with the state of our brain,

appearances that we often take for realities, and whose truths we have

to test by our faculty of reasoning, before we can set them down as

positive illusions. “In the most insignificant phenomena,” says Sir

David Brewster, “we find that the retina is so powerfully influenced by

exterior impressions as to retain the images of visible objects for a

long time after they have passed out of sight; besides, this portion of

the eye is so strongly influenced by local impressions of which we know

neither the nature nor the origin, that we see the shapeless forms of

coloured light moving about in the dark. In fact we have, in the cases

of Newton and many others, examples of the ease with which the

imagination revivifies the images of luminous objects for months or even

years, after these impressions took place. After the occurrence of such

phenomena, the mind can readily comprehend how thin is the division that

separates reality from those spectral illusions which during a

particular state of health have afflicted the most intelligent men, not

merely those belonging to the community at large, but also the most

learned philosophers.”

Spectres may properly be divided into two classes, those which may be

termed subjective, which result from some unnatural action of our minds

or bodies, and which properly belong to the science of physiology, and

those which may be called objective, which are caused by some peculiar

illusion acting on us from without. We shall pass lightly over the

first, illustrating them by a single example, while we shall pay more

serious attention to those belonging to the second class.

Sir Walter Scott, in his _Letters on Demonology and Witchcraft_,

mentions a remarkable instance of the first order of spectres. A doctor

of eminence was called in to attend a gentleman who occupied a high

place in a particular department connected with the administration of

justice. Until the time that the physician’s services became necessary,

he had shown strong common sense and extraordinary firmness and

integrity in every case in which he had been called upon to arbitrate.

But after a certain epoch his temper became saddened, although his mind

preserved its habitual strength and calmness. At the same time, the

feebleness of his pulse, the loss of appetite, and impaired digestion

seemed to point out to his medical adviser the existence of some serious

source of disturbance. At first the sick man seemed inclined to keep the

cause of the change in his health a profound secret; but his melancholy

bearing, confused answers, and the badly disguised constraint with which

he sharply replied to the interrogations of the doctor, caused the

latter to seek for information as to the cause of the disorder in other

directions. He made minute inquiries of the various members of his

unhappy patient’s family, but he could obtain no explanation of the

mystery. Every one was lost in conjecture as to the reason of the

alarming condition of the patient, which did not appear to be justified

by any loss of fortune or beloved friends. His age rendered the idea of

an unsuccessful love affair improbable, and his known integrity

precluded the possibility of remorse. The doctor accordingly was

compelled to return once more to the straight road, and he used the most

serious arguments with his patient to induce him to conquer his

obstinacy. At last the doctor’s efforts took effect; the patient allowed

himself to be convinced, and manifested his desire to open his mind

frankly to the doctor. They were accordingly left alone, all the doors

were securely fastened, and the patient made the following singular

avowal.

“You cannot be more firmly convinced, my dear friend, than I am myself,

that I am on the eve of death, crushed by the fatal malady which has

dried up the sources of my life. You remember, without doubt, the

disease of which the Duke of Olivarez died in Spain?”

“From the idea,” replied the doctor, “that he was pursued by an

apparition in whose existence he did not believe, and he died from the

continual presence of this imaginary vision weighing down his strength,

and breaking his heart.”

“Well, my dear doctor,” the patient went on, “I am in the same

condition, and the presence of the vision that persecutes me is so

painful and frightful, that my reason is totally helpless in controlling

the effects of my imagination, and I feel that I am dying from the

effects of an imaginary illness. My visions began two or three years

since. At first I found myself embarrassed from time to time by the

presence of a great cat, which appeared and disappeared I knew not how.

But at last the truth flashed across my mind, and I was compelled to

look upon the creature, not as an ordinary domestic animal, but as a

vision which had its origin in some derangement of the organs of sight

or in my imagination. I have no antipathy to cats, in fact I am rather

fond of them, so I endured the presence of my imaginary companion so

well that at last I treated the whole affair with indifference. But at

the end of several months the cat disappeared, and was replaced by a

spectre of greater importance, and whose exterior was, to say the least

of it, very imposing. It was neither more nor less than one of the high

officials of the House of Lords, in the full dress belonging to his

dignity.

“This personage, who was in court dress, with a bag-wig on his head, and

a sword by his side, his coat splendidly embroidered and his _chapeau

bras_ under his arm, glided along by my side like a shadow. Whether I

was in my own house or elsewhere, he mounted the stairs before me, as if

to announce my coming. Sometimes he seemed to mix with the company,

although it was evident that no one remarked his presence, and I was the

sole witness of the chimerical honours that this imaginary individual

seemed to render to me. This phantasy of my brain did not make a very

strong impression on me, although it made me conceive doubts as to the

state of my health, and the effects it would produce upon my reason.

“This second phase of my malady, like the first, also came to an end.

Some months after, the usher of the Upper House ceased showing himself,

and he was replaced by an apparition that was at once wearing to the

mind and terrible to the sight. It was a skeleton. Whether I was alone

or in company this frightful image of death never quitted me; it dogged

my footsteps and followed me everywhere, and seemed to be a shadow

inseparable from myself. It was in vain that I repeated to myself a

hundred times over that the vision was not real, and was only an

illusion of my senses. The reasoning of philosophy and my religious

principles, strong though they are, are powerless to triumph over the

influence that besets me, and I feel that I shall die a victim to this

cruel evil.”

“It seems then,” interrupted the doctor, “that this skeleton is always

before your eyes?”

“It is my evil fate to see it continually before me.”

“In which case it is at this moment visible to your eyes?”

“It is at present.”

“And in what part of the room do you imagine that you see it now?” asked

the doctor.

“At the foot of my bed,” replied the patient: “when the curtains are

half open I can see it place itself in the empty space between them.”

“You say that you are convinced that it is only an illusion,” replied

the doctor; “have you the firmness to convince yourself of it

positively? Have you the necessary courage to get up and go and place

yourself in the position which appears to be occupied by the spectre, in

order to demonstrate to yourself positively that it is only a vision?”

The unfortunate man sighed and shook his head.

“Well,” went on the doctor, “let us try another plan.”

He quitted the chair on which he was sitting, at the head of his

patient’s bed, and placing himself between the half opened curtains, in

the place where the patient had pointed out the skeleton, he asked if

the apparition was still visible.

“Not the whole of it,” answered the patient, “because you are standing

between him and me; but I see his skull looking at me over your

shoulder.”

In spite of his philosophy, the learned physician could not help

starting to hear that the spectre was immediately behind him. He had

recourse to other questions, and tried endless remedies, but without

success. The prostration of the patient, however, increased, and he died

in the same distress of mind in which he had passed the last months of

his life. This example is a sad proof of the power of the imagination

over the life of the body even when the terrors endured are powerless in

destroying the judgment of the unfortunate sufferer. We will say more;

men who have the strongest nerves are not free from similar illusions.

The second kind of spectres, in which the science of optics plays so

important a part, is the result of the imagination being deceived by art

with the assistance of science.

These spectres are displayed in the ghost trick which has been practised

at various Parisian theatres for a number of years, with very great

success, more especially at the _Théâtres du Châtelet_ and _Dejazet_.

The Adelphi, in London, also employed Mr. Pepper to heighten the effect

of the excellent acting of Mr. Toole and Mrs. Alfred Mellon, in the

dramatic version of Dickens’ “Haunted Man,” by the introduction of

various spectral effects. And the same trick was also called into

requisition with some success in several of the minor theatres in New

York and other cities of the United States. At the Polytechnic, in

London, very remarkable effects were produced, and few who ever saw them

will forget the surprise they felt at seeing the first representation of

an imponderable ghost endowed with motion, and even speech. Amongst the

most successful productions in this way was the entertainment of M.

Robin, one of the cleverest of the many successors of the great Robert

Houdin, the prince of prestidigitators. M. Robin claims to be the

inventor of the ghost illusion, and to have shown it frequently since

1847. Whether this be so or not it is not our business to decide, but we

can testify that his exhibition in the Boulevard du Temple drew all

Paris to see it. Evening after evening he not only “called spirits from

the vasty deep,” but “made them come.” He pierced them with swords, he

fired pistols through them, and he made them appear and disappear at his

slightest wish. He showed the Zouave at Inkermann, lying dead amongst a

heap of slain, who at the familiar sound of the drum, rose, pale and

grave, and showed the bleeding wounds from which he died. Amongst other

scenes shown by M. Robin was one of a spectre appearing to an armed man,

who after trying in vain to shut out the vision from his sight fires a

pistol at the intruder. Fig. 72 shows the scene as seen by the audience,

and fig. 73, the method by which the illusion is worked. The theatre is

shown in section. On the left, at the end, are seen the spectators; on

the right is the stage upon which the scene is represented. Beneath the

stage is an actor clothed in white to personate a ghost, whose image is

reflected by the glass above.

This glass is placed at an angle, and fills up the whole of the front of

the stage, the edges being carefully concealed by curtains. The glass of

course must be of a very large size, and should be of the very best

quality, so that it cannot be seen by the audience. The actor must take

care to place himself in such a position as to counteract the effect

produced by the glass being placed at an angle. At first the cavalier is

seen sitting at a table. After soliloquizing for a time in a very

remorseful manner touching several murders that he has committed, the

ghost of one of his victims gradually appears. This is effected by

gently turning the electric light upon the concealed actor. The murderer

and victim parley for a short time, when the former, being unable to

withstand the reproaches of the ghost any longer, fires a pistol at him

point-blank. The ball of course takes no effect, so the villain draws a

sword, but before it has left its scabbard the spirit of the victim has

vanished with a mocking laugh, or, in other words, the electric light is

suddenly turned off. The management of the light is exceedingly

difficult under these circumstances; the theatre, the stage, and the

portion beneath ought to be lighted in a very careful manner, for if

either is too bright or too dark it mars the whole effect. It must be

remembered, too, that the person performing the part of the spectre and

the real actor above cannot see each other, consequently all their

action has to be carried on by guess-work. The actor below has to walk

along an inclined plane, keeping himself exactly at right angles to it.

Again, the movements of the latter are obliged to be reversed; for the

cavalier already mentioned drew his sword with his left hand in order

that the reflected figure should appear to use the right.

When well arranged, the ghost trick leaves far behind all the efforts of

a similar nature that were obtained by the ancients in the way of

magical illusions. It is also incontestably true, contrary to what some

people have supposed, that they were unable to perform this illusion in

the way we have described, for they were ignorant of the method of

manufacturing and polishing glass plates of sufficient size and

clearness for the purpose.

The production of living but impalpable spectres is thus a completely

modern achievement, as we have already proved, and which has taken its

place amongst the applications of science to stage art, to the total

exclusion of all effects depending for their production on the

old-fashioned phantasmagoria and magic lantern.
