3. The memory and circle of ideas are curiously circumscribed.

4. To make up for this, some of the powers of the mind acquire

concentration and temporary increase of force, and occasionally new

powers of apprehension appear to be developed.

5. Spasms of the muscles, generally tonic or maintained spasms, but

sometimes, having the character of convulsive struggles, are

occasionally manifested in trance. And they may bear either of two

relations to it. They may occur simultaneously with trance-waking or

alternately with it, and occupying the patient's frame in the intervals

of trance.

In the ordinary course of things, trance-sleep precedes trance-waking,

and follows it. So that some have described trance-waking as waking in

trance. Trance-sleep may come on during ordinary sleep, or during

ordinary waking. By use the introductory and terminal states of

trance-sleep become abridged; and sometimes, if either exist, it is so

brief, that the transition to and from trance-waking out of and into

ordinary waking, _appears_ immediate.

Now to illustrate the phenomena of trance half-waking, by describing

somnambulism.

A curious fate somnambulism has had. When other forms of trance have

been exalted into mystical phenomena and figure in history, somnambulism

has had no superstitious altars raised to her--has had no

fear-worship--has at the highest been promoted to figure in an opera. Of

a quiet and homely nature, she has moved about the house, not like a

visiting demon, but as a maid of all work. To the public, the phenomenon

has presented no more interest than a soap-bubble or the fall of an

apple.

Somnambulism is a form of half-waking trance which usually comes on

during the night, and in ordinary sleep. When it occurs in the daytime,

the attack of trance is still ordinarily preceded by a short period of

common sleep.

The somnambulist then, half waking in trance, is disposed to rise and

move about. Sometimes his object seems a mere excursion, and then it is

remarked that he shows a disposition to ascend heights. So he climbs,

perhaps, to the roof of the house, and makes his way along it with

agility and certainty: sometimes he is observed, where the tiles are

loose, to try if they are secure before he advances. Generally these

feats are performed in safety. But occasionally, a somnambulist has

missed his footing, fallen, and perished. His greatest danger is from

ill-judged attempts to wake and warn him of his perilous situation.

Luckily, it is not easy to wake him. He then returns, goes to bed,

sleeps, and the next morning has no recollection of what he has done. In

other cases, the somnambulist, on rising from his bed, betakes himself

to his customary occupations, either to some handiwork, or to

composition, or what not.

These three points are easily verifiable respecting his condition. He is

in a dream, which he, as it were, acts after his thoughts; occasionally

he remembers on the following day some of the incidents of the night

before, as part of a dream.

But his common sensibility to ordinary impressions is suspended: he does

not feel; his eyes are either shut, or open and fixed; he does not see;

he does not observe light, and works as well with as without it; he has

not taste or smell: the loudest noise makes no impression on him.

In the mean time, to accomplish the feats he performs, the most accurate

_perception_ of sensible objects is required. Of what nature is that of

which he so marvellously evinces the possession? You may adopt the

simple hypothesis,--that the mind, being disengaged from its ordinary

relations to the senses, does without them, and perceives things

directly. Or you may suppose, if you prefer it, that the mind still

employs sensation, using only impressions that in ordinary waking are

not consciously attended to, for its more wonderful feats; and otherwise

common sensation, which, however generally suspended, may be awakened by

the dreaming attention to its objects.

The following case of somnambulism, in which the seizure supervened, in

a girl affected with St Vitus's dance, and combined itself with that

disorder, is given by Lord Monboddo:--

The patient, about sixteen years of age, used to be commonly taken in

the morning a few hours after rising. The approach of the seizure was

announced by a sense of weight in the head, a drowsiness which quickly

terminated in sleep, in which her eyes were fast shut. She described a

feeling beginning in the feet, creeping like a gradual chill higher and

higher, till it reached the heart, when consciousness or recollection

left her. Being in this state, she sprang from her seat about the room,

over tables and chairs, with the astonishing agility belonging to St

Vitus's dance. Then, if she succeeded in getting out of the house, she

ran at a pace with which her elder brother could hardly keep up, to a

particular spot in the neighbourhood, taking the directest but the

roughest path. If she could not manage otherwise, she got over the

garden-wall with surprising rapidity and precision of movement. Her eyes

were all the time fast closed. The impulse to visit this spot she was

often conscious of during the approach of the paroxysm, and, afterwards,

she sometimes thought she had dreamed of going thither. Towards the

termination of her indisposition, she dreamed that the water of a

neighbouring spring would do her good, and she drank much of it. One

time they tried to cheat her by giving her water from another spring,

but she immediately detected the difference. Towards the end, she

foretold that she would have three paroxysms more, and then be well--and

so it proved.

The following case is from a communication by M. Pigatti, published in

the July Number of the _Journal Encyclopedique_ of the year 1762. The

subject was a servant of the name of Negretti, in the household of the

Marquis Sale.

In the evening, Negretti would seat himself in a chair in the anteroom,

when he commonly fell asleep, and would sleep quietly for a quarter of

an hour. He then righted himself in his chair, so as to sit up. [This

was the moment of transition from ordinary sleep into trance.] Then he

sat some time without motion, as if he saw something. Then he rose and

walked about the room. On one occasion, he drew out his snuff-box and

would have taken a pinch, but there was little in it; whereupon he

walked up to an empty chair, and addressing by name a cavalier whom he

supposed to be sitting in it, asked him for a pinch. One of those who

were watching the scene, here held towards him an open box, from which

he took snuff. Afterwards he fell into the posture of a person who

listens; he seemed to think that he heard an order, and thereupon

hastened with a wax-candle in his hand, to a spot where a light usually

stood. As soon as he imagined that he had lit the candle, he walked with

it in the proper manner, through the _salle_, down the steps, turning

and waiting from time to time, as if he had been lighting some one down.

Arrived at the door, he placed himself sideways, so as to let the

imaginary persons pass, and he bowed as he let them out. He then

extinguished the light, returned up the stairs, and sat himself down

again in his place, to play the same farce over again once or twice the

same evening. When in this condition, he would lay the tablecloth, place

the chairs, which he sometimes brought from a distant room, and opening

and shutting the doors as he went, with exactness; would take decanters

from the _beauffet_, fill them with water at the spring, put them on a

waiter, and so on. All the objects _that were concerned in these

operations_, he distinguished where they were before him with the same

precision and certainty as if he had been in the full use of his senses.

Otherwise he seemed to observe nothing--so, on one occasion, in passing

a table, he upset a waiter with two decanters upon it, which fell and

broke, without exciting his attention. The dominant idea had entire

possession of him. He would prepare a salad with correctness, and sit

down and eat it. Then, if they changed it, the trick passed without his

notice. In this manner he would go on eating cabbage, or even pieces of

cake, seemingly without observing the difference. The taste he enjoyed

was imaginary; the sense was shut. On another occasion, when he asked

for wine, they gave him water, which he drank for wine, and remarked

that his stomach felt the better for it. On a fellow-servant touching

his legs with a stick, the idea arose in his mind that it was a dog, and

he scolded to drive it away; but the servant continuing his game,

Negretti took a whip to beat the dog. The servant drew off when Negretti

began whistling and coaxing to get the dog near him; so they threw a

muff against his legs, which he belaboured soundly.

M. Pigatti watched these proceedings with great attention, and convinced

himself by many trials that Negretti did not use his senses. The

suspension of taste was shown by his not distinguishing between salad

and cake. He did not hear the loudest sound, when it lay out of the

circle of his dreaming ideas. If a light was held close to his eyes,

near enough to singe his eyebrows, he did not appear to be aware of it.

He seemed to feel nothing when they inserted a feather into his

nostrils. The ordinary sensibility of his organs seemed withdrawn.

Altogether, the most interesting case of somnambulism on record, is that

of a young ecclesiastic, the narrative of which, from the immediate

communication of an Archbishop of Bordeaux, is given under the head of

somnambulism in the French Encyclopaedia.

This young ecclesiastic, when the archbishop was at the same seminary,

used to rise every night, and write out either sermons or pieces of

music. To study his condition, the archbishop betook himself several

nights consecutively to the chamber of the young man, where he made the

following observations.

The young man used to rise, to take paper, and to write. Before he wrote

music, he would take a stick and rule the lines with it. He wrote the

notes, together with the words corresponding with them, with perfect

correctness. Or, when he had written the words too wide, he altered

them. The notes that were to be black, he filled in after he had written

the whole. After completing a sermon, he read it aloud from beginning to

end. If any passage displeased him, he erased it, and wrote the amended

passage correctly over the other; on one occasion he had to substitute

the word "_adorable_" for "_divin_;" but he did not omit to alter the

preceding "_ce_" into "_cet_," by adding the letter "_t_" with exact

precision to the word first written. To ascertain whether he used his

eyes, the archbishop interposed a sheet of pasteboard between the

writing and his face. He took not the least notice, but went on writing

as before. The limitation of his perceptions to what he was thinking

about was very curious. A bit of aniseed cake, that he had sought for,

he eat approvingly; but when, on another occasion, a piece of the same

cake was put in his month, he spit it out without observation. The

following instance of the dependance of his perceptions upon, or rather

their subordination to, his preconceived ideas is truly wonderful. It is

to be observed that he always knew when his pen had ink in it.

Likewise, if they adroitly changed his papers, when he was writing, he

knew it, if the sheet substituted was of a different size from the

former, and he appeared embarrassed in that case. But if the fresh sheet

of paper, which was substituted for that written on, was exactly of the

same size with the former, he appeared not to be aware of the change.

And he would continue to read off his composition from the blank sheet

of paper, as fluently as when the manuscript itself lay before him; nay,

more, he would continue his corrections, and introduce the amended

passage, writing it upon exactly the place on the blank sheet which it

would have occupied on the written page.

The form of trance which has been thus exemplified may be therefore well

called half-waking, inasmuch as the performer, whatever his powers of

perception may be in respect to the object he is thinking of, is

nevertheless lost in dream, and blind and deaf to every thing without

its scope.

The following case may serve as a suitable transition to instances of

full-waking in trance. The subject of it alternated evidently between

that state and half-waking. Or she, could be at once roused from the

latter into the former by the conversation of her friends. The case is

recorded in the Acta Vratisl. ann. 1722, Feb. class iv., art. 2.

A girl seventeen years of age was used to fall into a kind of sleep in

the afternoon, in which it was supposed, from her expression of

countenance and her gestures, that she was engaged in dreams which

interested her. After some days, she began to speak when in this state.

Then, if those present addressed remarks to her, she replied very

sensibly; but then fell back into her dream-discourse, which turned

principally upon religious and moral topics, and was directed to warn

her friends how a female should live, Christianly, well-governed, and so

as to incur no reproach. When she sang, which often happened, she heard

herself accompanied by an imaginary violin or piano, and would take up

and continue the accompaniment upon an instrument herself. She sewed,

did knitting, and the like. But on the other hand, she imagined on one

occasion that she wrote a letter upon a napkin, which she folded with

the intention of sending it to the post. Upon waking, she had not the

least recollection of her dreams, or of what she had been doing. After a

few months she recovered.

I come now to the exemplification of full-waking in trance, as it is

very perfectly manifested in the cases which have been termed double

consciousness. These are in their principle very simple; but it is not

easy in a few words to convey a distinct idea of the condition of the

patient. The case consists of a series of fits of trance, in which the

step from ordinary waking to full trance-waking is sudden and immediate,

or nearly so, and either was so originally, or through use has become

so. Generally for some hours on each day, occasionally for days

together, the patient continues in the state of trance; then suddenly

reverts to that of ordinary waking. In the perfectest instances of

double consciousness, there is nothing in the bearing or behaviour of

the entranced person which would lead a stranger to suppose her (for it

is an affection far commoner in young women than in boys or men) to be

other than ordinarily awaked. But her friends observe that she does

every thing with more spirit and better--sings better, plays better, has

more readiness, moves even more gracefully, than in her natural state.

She has an innocent boldness and disregard of little conventionalisms,

which imparts a peculiar charm to her behaviour. In the mean time, she

has two complete existences separate and apart, which alternate but

never mingle. On the day of her first fit, her life split into a double

series of thoughts and recollections. She remembers in her ordinary

state nothing of her trance existence. In her trances, she remembers

nothing of the intervening hours of ordinary waking. Her recollections

of what she had experienced or learned before the fits began is

singularly capricious, differing extraordinarily in its extent in

different cases. In general, the positive recollection of prior events

is annulled; but her prior affections and habits either remain, and her

general acquirements, or they are quickly by association rekindled or

brought into the circle of her trance ideas. Generally she names all her

friends anew; often her tone of voice is a little altered; sometimes she

introduces with particular combinations of letters some odd inflection,

which she maintains rigorously and cannot unlearn.

Keeping before him this conception, the reader will comprehend the

following sketch of a case of double consciousness, communicated by Dr

George Barlow. To one reading them without preparation, the details,

which are very graphic and instructive, would appear mere confusion:--

"This young lady has two states of existence. During the time that the

fit is on her, which varies from a few hours to three days, she is

occasionally merry and in spirits; occasionally she appears in pain and

rolls about in uneasiness; but in general she seems so much herself,

that a stranger entering the room would not remark any thing

extraordinary; she amuses herself with reading or working, sometimes

plays on the piano and better than at other times, knows every body, and

converses rationally, and makes very accurate observations on what she

has seen and read. The fit leaves her suddenly, and she then forgets

every thing that has passed during it, and imagines that she has been

asleep, and sometimes that she has dreamed of any circumstance that has

made a vivid impression upon her. During one of these fits she was

reading Miss Edgeworth's tales, and had in the morning been reading a

part of one of them to her mother, when she went for a few minutes to

the window, and suddenly exclaimed, 'Mamma, I am quite well, my headach

is gone.' Returning to the table, she took up the open volume, which she

had been reading five minutes before, and said, 'What book is this?' she

turned over the leaves, looked at the frontispiece, and replaced it on

the table. Seven or eight hours afterwards, when the fit returned, she

asked for the book, went on at the very paragraph where she had left

off, and remembered every circumstance of the narrative. And so it

always is; as she reads one set of books during one state, and another

during the other. She seems to be conscious of her state; for she said

one day, 'Mamma, this is a novel, but I may safely read it; it will not

hurt my morals, for, when I am well, I shall not remember a word of

it.'"

This state of double consciousness forms the basis of the psychical

phenomena observed in the extraordinary cases which have been

occasionally described under the general name of catalepsy. The accounts

of the most interesting of these that I have met with, were given by M.

Petatin in 1787; M. Delpet, 1807; Dr Despine, 1829. The wonderful powers

of perception evinced by the patients when in this state of

trance-waking would exceed belief, but for the respectable names of the

observers, and the internal evidence of good faith and accuracy in the

narratives themselves. The patients did not see with their eyes nor hear

with their ears. But they heard at the pit of the stomach, and perceived

the approach of persons when at some distance from their residence, and

read the thoughts of those around.

I am, my dear Archy, no wonder-monger; so I am not tempted to make a

parade to you of these extraordinary phenomena. Nor in truth do they

interest me further than as they concur with the numerous other facts I

have brought forward to show, and positively prove, that under certain

conditions the mind enters into new relations, spiritual and material. I

will, however, in conclusion, give you the outline of a case of the sort

which occurred a few years ago in England, and the details of which were

communicated to me by the late Mr Bulteel. He had himself repeatedly

seen the patient, and had scrupulously verified what I now narrate to

you:--

The patient was towards twenty years of age. Her condition was the state

of double consciousness, _thus_ aggravated, that when she was not in the

trance, she suffered from spasmodic contraction of the limbs. In her

alternate state of trance-waking, she was composed and apparently well;

but the expression of her countenance was slightly altered, and there

was some peculiarity in her mode of speaking. She would mispronounce

certain letters, or introduce consonants into words upon a regular

system; and to each of her friends she had given a new name, which she

only employed in her trance. As usual, she knew nothing in either state

of what passed in the other. Then in her trance she exhibited three

marvellous powers: she could read by the touch alone: if she pressed her

hand against the whole surface of a written or printed page, she

acquired a perfect knowledge of its contents, not of the substance only,

but of the words, and would criticise the type or the handwriting. A

line of a folded note pressed against the back of her neck, she read

equally well: she called this sense-feeling. Contact was necessary for

it. Her sense of smell was at the same time singularly acute; when out

riding one day, she said, "There is a violet," and cantered her horse

fifty yards to where it grew. Persons whom she knew she could tell were

approaching the house, when yet at some distance. When persons were

playing chess at a table _behind her_, and intentionally made impossible

moves, she would smile, and ask them why they did it.

Cases of this description are no doubt of rare occurrence. Yet not a

year passes in London without something transpiring of the existence of

one or more of them in the huge metropolis. Medical men view them with

unpardonable indifference. Thus one doctor told me of a lady, whom he

had been attending with other physicians, who, it appeared, always

announced that they were coming some minutes before they drove to her

door. It was very odd, he thought, and there was an end of it.

"M. l'Abbe," said Voltaire to a visitor, who gave him a commonplace

account of some remarkable scenes, "do you know in what respect you

differ from Don Quixote?"--"No," said the Abbe, not half liking the look

of the question. "Why, M. l'Abbe, Don Quixote took the inns on the road

for castles, but you have taken castles for inns."

Adieu, dear Archy.--Yours, &c.

MAC DAVUS.
