In the public process several women are magnetised at the same time,

and they experience at first no effects but such as are similar to

those, obtained by the commissioners in various experiments. It is even

acknowledged that for the most part the crises do not commence in less

than the space of two hours. By little and little the impressions are

communicated from one to another, and reinforced, in the same manner as

the impressions which are made by theatrical representation, where the

impressions are greater in proportion to the number of the spectators,

and the liberty they enjoy of expressing their sensations. The

applause, by which the emotions of individuals are announced, occasions

a general emotion, which every one partakes in the degree in which he

is susceptible. The same observation has been made in armies upon a day

of battle, where the enthusiasm of courage, as well as the impressions

of terror, are propagated with so amazing rapidity. The drum, the sound

of the military musical instruments, the noise of the cannon, the

musquetry, the shouts of the army, and the general disorder impress the

organs, have a uniform effect upon the understanding, and exalt the

imagination in the same degree. In this equilibrium of inebriation,

the external manifestation of a single sensation immediately becomes

universal; it hurries the soldiery to the charge, or it determines them

to fly. The same cause is deeply concerned in rebellions; the multitude

are governed by the imagination; the individuals in a numerous assembly

are more subjected to their senses, and less capable of submitting to

the dictates of reason; and where fanaticism is the presiding quality,

its fruit is the tremblers of the Cevennes[12]. It has been usual to

forbid numerous assemblies in seditious towns, as a means of stopping

a contagion so easily communicated. Every where example acts upon

the moral part of our frame, mechanical imitation upon the physical

part: the minds of individuals are calmed by dispersing them; the same

method puts a stop to their spasmodic affections, always contagious in

their nature: we have had a recent example of this in the young ladies

of Saint Roch, who were in this manner cured of the convulsions with

which they were affected when together[13].

The magnetism then, or rather the operations of the imagination,

are equally discoverable at the theatre, in the camp, and in all

numerous assemblies, as at the bucket, acting indeed by different

means, but producing similar effects. The bucket is surrounded with

a crowd of patients; the sensations are continually communicated and

recommunicated; it ought to be expected that the nerves should be at

length worn out with this exercise, they are accordingly irritated,

and the woman of most sensibility in the company gives the signal.

Immediately the cords, every where stretched to the same degree and

in perfect unison, respond to each other; the crises are multiplied;

they mutually reinforce each other, and are rendered violent. In the

mean time the men, who are witnesses of these emotions, partake of them

in proportion to their nervous sensibility; and those with whom this

sensibility is greatest and most easily excited become themselves the

subjects of a crisis.

This propensity to irritation, partly natural and partly acquired,

becomes in each sex habitual. The sensations having been felt once or

oftener, nothing is now necessary, but to recal the memory of them, and

to exalt the imagination to the same degree, in order to operate the

same effects. This will never be difficult when the subject is placed

in the same circumstances. The public process is no longer necessary,

you have only to touch the hypochonders and to conduct the finger and

the rod of iron before the countenance; the signs are well known.

Even these are not necessary, it is sufficient that the patients be

blindfolded, made to believe that these signs are repeated upon them,

and that they are magnetised; the ideas are reexcited, the sensations

are reproduced, the imagination, employing its accustomed instruments

and resuming its former routes, gives birth to the same phenomena.

These cases happen exactly to the patients of M. Deslon, who fall

into a crisis without the bucket, and without being excited with the

spectacle of the public process.

Compression, imagination, imitation are therefore the true causes of

the effects attributed to this new agent, known by the appellation

of animal magnetism, this fluid, which is said to circulate through

the human body, and to be communicated from individual to individual.

Such is the result of the experiments of the commissioners, and

the observations they made upon the means employed and the effects

produced. This agent, this fluid has no existence. Chimerical however

as it is, the idea is by no means novel. Some authors, particularly

physicians of the last age, have expressly treated of it in various

performances. The curious and interesting enquiries of M. Thouret have

convinced the public, that the theory, the operations and the effects

of the animal magnetism, proposed in the last age, were nearly the same

with those revived in the present. The magnetism then is no more than

an old falshood. The theory indeed is now presented, as was necessary

in a more enlightened age, with a greater degree of pomp; but it is

not less erroneous. Human nature is formed to seize, to quit and to

resume the mistake which is flattering to its wishes. There are errors

which will be eternally dear to the sublunary state. How often has the

pretended science of astrology vanished and reappeared! The magnetism

is calculated to lead us back to it. Its professors have been desirous

of connecting it with the celestial influences, that it might have

the stronger seduction, and attract mankind by the two hopes that

are nearest their heart, that of looking into futurity, and that of

prolonging their existence.

There is room to believe that the imagination is the principal of the

three causes which we have assigned to the magnetism. It appears by

the experiments we have related that it suffices alone to produce the

crises. The pressure and the touch seem to serve it as preparatives;

it is by the touch that the nerves begin to be excited, imitation

communicates and extends the impressions. But the imagination is that

active and terrible power, by which are operated the astonishing

effects, that have excited so much attention to the public process. The

effects strike all the world, the cause is enveloped in the shades

of obscurity. When we consider that these effects seduced in former

ages men, venerable for their merit, their illumination and even their

genius, Paracelsus, Van Helmont and Kircher, we cease to be astonished,

that persons of the present day, learned and well informed, that even

a great number of physicians have been the dupes of this system. Had

the commissioners been admitted only to the public process, where there

is neither time nor opportunity of making decisive experiments, they

might themselves have been led into error. It was necessary to have

liberty to insulate the effects, in order to distinguish the causes; it

was necessary to see as they have done the imagination act, if we may

be allowed the expression, partially, and produce its effects one by

one and in detail, to have an idea to what the accumulation of those

effects might amount; to conceive the extent of its power, and to

account for all its prodigies. Such an examination demanded a sacrifice

of time, and a number of systematical researches, which we have not

always the leisure to undertake for our private instruction or private

curiosity, nor even the power properly to pursue without being like the

commissioners charged with the mandates of the sovereign, and honoured

with the confidence of the public.

M. Deslon is not much averse to the admission of these principles.

He declared in our session held at the house of Dr. Franklin the

19th of June, that he thought he might lay it down as a fact, that

the imagination had the greatest share in the effects of the animal

magnetism; he said that this new agent might be no other than the

imagination itself, whose power is as extensive as it is little known:

he affirmed that he always acknowledged the concern of this faculty in

the treatment of his patients, and he affirmed with equal confidence

that many persons have been either entirely cured or infinitely

amended in the state of their health under his direction. He remarked

to the commissioners that the imagination thus directed to the relief

of suffering humanity, would be a most valuable means in the hands

of the medical profession[14]; and persuaded of the reality of the

power of the imagination, he invited the commissioners to embrace the

opportunity which his practice afforded to study its procedure and

its effects. If therefore M. Deslon be still attached to his first

idea, that these effects are to be ascribed to the agency of a fluid,

which is communicated from individual to individual by the touch or

under the guidance of a conductor, he cannot however avoid conceding

to the commissioners that only one cause is requisite to one effect,

and that since the imagination is a sufficient cause, the supposition

of the magnetic fluid is useless. It cannot be denied that we are

surrounded with a fluid which peculiarly belongs to us; the insensible

perspiration forms around us an atmosphere of insensible vapours: but

this fluid has no agency but such as is common to other atmospheres;

cannot be communicated by the touch but in infinitely small quantities;

is not capable of being directed either by conductors, or by the eyes,

or by the will; is neither propagated by sound, nor reflected by

mirrors; and is in no case susceptible of the effects ascribed to it.

It remains for us to enquire, whether the crises or convulsions,

excited by the methods of the pretended magnetism in the assemblies

round the bucket, be capable of any utility, or be calculated to

cure or relieve the patients. The imagination of sick persons has

unquestionably a very frequent and considerable share in the cure of

their diseases. With the effect of it we are unacquainted otherwise

than by general experience; but, though it has not been traced in

positive experiments, it should seem not to admit of a reasonable

doubt. It is a known adage, that in physic as well as religion, men

are saved by faith; this faith is the produce of the imagination: in

these cases the imagination acts by gentle means; it is by diffusing

tranquility over the senses, by restoring the harmony of the functions,

by recalling into play every principle of the frame under the genial

influence of hope. Hope is an essential constituent of human life; the

man that yields us one contributes to restore to us the other. But when

the imagination produces convulsions, the means it employs are violent;

and such means are almost always destructive. There are indeed a few

rare cases in which they may be useful; there are desperate diseases,

in which it is necessary to overturn every thing for the introduction

of an order totally new. These critical shocks are to be employed in

the medical art in the same manner as poisons. It is requisite that

necessity should demand, and œconomy employ them. The need of them

is momentary; the shock ought to be single. Very far from repeating

it, the intelligent physician exerts himself to invent the means of

repairing the indispensible evil which has thus been produced; but

in the public process of the magnetism the crises are repeated every

day, they are long and violent. Now since the state introduced by

these crises is pernicious, the habit cannot be other than fatal. How

indeed can it be conceived, that a woman, attacked for instance with

a pulmonary distemper, can undergo with impunity a crisis, some of

whose symptoms are a convulsive cough and compulsory expectorations; or

can safely fatigue, perhaps shatter the lungs by violent and repeated

efforts, when so great pains are necessary to convey to the wounded

frame the sanative and the balsamic? How can we imagine that a man,

be his disorder what it will, can need in order to his recovery the

intervention of crises, in which the sight appears to be lost, the

members stiffen, he strikes his breast with precipitate and involuntary

motions; crises in a word, that are terminated by an abundant spitting

of viscous humours and even blood? The blood thus discharged is neither

vitiated nor corrupted, it flows from vessels from which it is torn by

the violence of effort and contrary to the intention of nature; these

effects are therefore to be regarded as a real not a salutary evil, an

evil additional to the distemper be it what it will.

Nor is this the only danger with which they are attended. Man is

incessantly enslaved by custom; nature is modified by habit only in

a progressive manner, yet she is often so completely modified, as to

suffer an entire metamorphosis, and to be scarcely capable of being

known for the same. Who will assure us that this state of crises, at

first voluntarily induced, shall not become habitual? And should the

habit thus contracted frequently reproduce the same symptoms, in spite

of the will, and almost without the assistance of the imagination, how

dreadful the fate of an individual, subjected to so violent effects,

tormented, as well morally as physically, with their unfortunate

impression, whose days should be divided between apprehension and

agony, and whose life should be an uninterrupted state of suffering!

Nervous distempers of this description, even when natural, are the

opprobrium of the medical science; how little ought it to be the

object of art to produce them! The art, which thus interferes with all

the functions of the animal œconomy, urges nature out of her proper

course, and multiplies the victims of irregularity, is to be regarded

as pernicious. Its effects are the more to be apprehended, since

it not only aggravates the disorder of the nerves by renewing their

symptoms, and causing them to degenerate into habit; but if a distemper

of this kind be contagious, as it may be suspected to be, the method of

provoking nervous convulsions and of exciting them in public assemblies

is a means to diffuse them in great towns, and even to afflict with

them generations to come, since the diseases and the habits of parents

are transmitted to their posterity.

The commissioners having convinced themselves, that the animal magnetic

fluid is capable of being perceived by none of our senses, and had no

action either upon themselves or upon the subjects of their several

experiments; being assured, that the touches and compressions employed

in its application rarely occasioned favourable changes in the animal

œconomy, and that the impressions thus made are always hurtful to the

imagination; in fine having demonstrated by decisive experiments,

that the imagination without the magnetism produces convulsions, and

that the magnetism without the imagination produces nothing; they

have concluded with an unanimous voice respecting the existence and

the utility of the magnetism, that the existence of the fluid is

absolutely destitute of proof, that the fluid having no existence

can consequently have no use, that the violent symptoms observed in

the public process are to be ascribed to the compression, to the

imagination called into action, and to that propensity to mechanical

imitation, which leads us in spite of ourselves to the repetition of

what strikes our senses. And at the same time they think themselves

obliged to add as an important observation, that the compressions and

the repeated action of the imagination employed in producing the crises

may be hurtful, that the sight of these crises is not less dangerous on

account of that imitation which nature seems to have imposed upon us as

a law, and that of consequence every public process, in which the means

of the animal magnetism shall be employed, cannot fail in the end of

producing the most pernicious effects[15].

FOOTNOTES:

[1] “It must be confessed however, that the manner of directing the

pretended magnetism, is different in these systems. The ancients, as

well as M. Mesmer, regarded this fluid as universally diffused, as

pervading the bodies of animals, and as capable of being rendered the

vehicle of the most salutary influences. But, in order to call it into

action, they did not, like M. Mesmer, desire to touch, or so much as

to approach the patient. Their method consisted in a different order

of proceeding. To give a suitable direction to the universal spirit,

they were obliged to employ real parts, either extracted or evacuated,

of the individual upon whom they proposed to direct the magnetism. The

different humours of the human body, whether natural, as the blood,

the urine, the excrements, or contrary to nature, as the pus bred in

wounds; in fine, the solid parts of the frame, as the flesh, the nails,

the hair, in a state of separation from the body, afforded, according

to the ancient doctrine, the suitable and necessary means of employing

the magnetism. These different parts, so long as they remained in a

state of integrity, were supposed to be united in the link of a common

vital principle with the individual who had furnished them. The union

was operated by the intervention of the universal spirit, and in

acting upon them, the physician was said to act also upon the person

to whom they had belonged; an action, which, as it was independent of

contact, and was not superseded by distance, was regarded as magnetic.”

_Thouret._

[2] “Far be it from me,” says Maxwel, “to lead you to improper

actions. If from the perusal of my works, you become acquainted

with the means of such actions, you will do me the justice not to

divulge them.--I have seen,” adds he, “the most incredible effects,

and the greatest advantages from a right use of this method. I have

also seen infinite evils occasioned by the abuse of it.--Indeed, it

is scarcely prudent to treat of these subjects, on account of the

dangers that may result from it. If we were to express ourselves in a

manner universally intelligible, fathers could never be sure of their

daughters, nor husbands of their wives; women would be deprived of

their self-government in spite of the most judicious and obstinate

resistance.” _Maxwel, de medicina magnetica, apud Thouret._

[3] Paracelsus Arecolus Philippus Theophrastus Bombastus de Hohenheim

is to be regarded as the inventor of the magnetical system. He was born

at a village near Zurich in Switzerland in 1493, and died in 1541. His

profession was that of a physician, and he obtained great reputation

by the use of mercury and opium, medicines that were unknown, or not

employed by the physicians of those times. But beside this, he was a

proficient in alchymy, astrology, and magic. He was acquainted with the

philosopher’s stone, and the universal medicine. And he invented an

elixir, in the use of which a man could not fail to live to the age of

a thousand years.

Van Helmont was the immediate successor of Paracelsus in the pursuit

of the magnetical science, and wrote an express treatise De Magnetica

Vulnerum Curatione.

All the other persons enumerated, lived in the seventeenth century.

“To Maxwel, we are particularly indebted for the most complete and

copious treatise upon the subject, in which he has endeavoured to

support its declining credit by calling in the assistance of that

theory of the universal spirit, which he derived from the earliest

philosophers of antiquity, and in which we are presented with the exact

counterpart of the system of M. Mesmer.

“Another inhabitant of this island, the learned and illustrious sir

Kenelm Digby, is well known for his invention of the sympathetic

powder; which it was only necessary to apply to the linnen which had

imbibed the blood or pus of a wound, or to the arm or sword of him who

inflicted it, provided they were still stained with the blood of the

wounded person. It was necessary however, that the wound should be kept

perfectly clean, and protected from the air.

“There was a sympathetic sweating powder, invented so lately as the

year 1745. The means of applying it was, by mixing it with the urine of

the person diseased, and keeping it boiling over a fire, as long as you

wished the perspiration to continue. During the operation, the patient

was to keep his bed, to be covered up warm, and to drink several large

basons of tea. This medicine was never known to fail of its effect.”

_Thouret._

[4] The experiments of the ring and sword, are to be found in Kircher’s

Magnes, sive de arte magnetica. They are both well known. “That of

the sword consists in the balancing it upon the point of one of the

fingers, the consequence of which will be a very rapid rotatory motion,

_provided the person be properly magnetised_. That of the ring is

performed by a person initiated in the animal magnetism, holding it

suspended by a thread in the inside of a wine glass, when it will

invariably strike the hour of the day.” _Thouret._

[5] “Valentine Greatrakes, esq; was a native of Afane, in the kingdom

of Ireland. We are told, that one day he was conscious to a wonderful

internal revolution, and at the same time heard a voice like that

of a genius, which cried incessantly for a long time: “I endow you

with the faculty of curing diseases.” Importuned by this salutation,

from which he could in no way distract his attention, he determined

to make an experiment of the truth of the intelligence. The voice

had first announced to him the gift of curing the king’s evil. He

made an experiment upon this distemper, and succeeded. He afterwards

touched persons attacked with an epidemical fever, that raged in his

neighbourhood; the voice had announced to him the gift of curing this

disease. In fine, he was enabled to cure every species of disease; and

he succeeded in all cases, except where, as he observed, the malady

was too deeply rooted, or the patient laboured under a particular

indisposition to this method of cure. The exterior of this man was

extremely simple. His cures were accompanied with no degree of pomp and

ceremony, unless we should call such, his ascribing his success to God,

publicly expressing his gratitude, and inviting the patient to join

with him in the act of thanksgiving. But he made a very extensive use

of the operation of touch. The distemper fled before him, and he was

able, we are told, to dislodge it from its seat, and remove it to parts

the least useful. If its progress appeared to be suspended in any part,

he redoubled his frictions upon that part, to remove the obstacle. In

this operation nature, excited by the stroking, seemed frequently to

operate crises, and it produced stools, vomitings and perspirations.”

_Thouret._

“Greatrakes cured not only internal diseases, but also external ones,

such as wounds and ulcers. The second Villiers, duke of Buckingham, was

one of his patients. His attestations were signed by Boyle, Wilkins,

Whichcot, Cudworth and Patrick. He was born in 1628, received the gift

of healing 1662, and removed to London 1666.” _Des Maizeaux, Vie de St.

Evremond_.

“The cures of Gassner are of a much later date, and are not above ten

or twelve years old. This German, having in his youth been afflicted

with an ill state of health, which resisted the efforts of all the

physicians, suspected that his distemper might have a supernatural

cause, and derive from the influence of the devil. His conjecture was

verified by his success in expelling the devil, having adjured him

in the name of Jesus Christ. From that moment he enjoyed the most

perfect health for sixteen years. Encouraged by this event, he laid

aside the study of medicine, to which his distemper had prompted him,

and procured all the authors who had treated of exorcism. He began

with healing his parishioners in an obscure town upon the borders

of Switzerland and the Tirol, and his reputation increased so much,

that, in the two last years of his residence there, he had between

four and five hundred patients who applied to him. He then made a

progress through several of the Swiss cantons, and settled at Ratisbon

in 1774. He distinguished diseases into two classes, the natural and

the demoniac, the last of which were much the most numerous. Over the

former he pretended to no power. His cures were performed with much

pomp and solemnity; and it was observed, that he constantly rubbed his

hands upon his girdle and handkerchief previously to his touching the

patient. He performed his cures in the name of Christ, and by the faith

of the diseased in his holy name; if their faith failed, the cure did

not take place. He gave the sick, when he dismissed them, balm and oil,

which he considered as spiritual medicaments, together with certain

waters and powders, and a little ring, inscribed with the name of

Jesus, to prevent a relapse.” _Thouret._

Thouret considers the system of Gassner as having had an influence on

that of M. Mesmer. Astrology and possessions were extremely current

in Germany; and as Gassner had taken possession of, and ruined the

latter pretension, Mesmer had recourse to the former. It should however

be remembered, that Mesmer had written and published his thesis upon

astrology before the pretensions of Gassner were heard of.
