One of the most dazzling and successful inventors in modern times, was Messmer, who commenced his career of medical knight-errantry at Vienna. His house was the focus of high life, the rendezvous of the gay, where the young and opulent were enlivened and entertained with continual concerts, routs, and illuminations. At a great expence, he imported into Germany the first Harmonica from this country: he established cabinets of natural curiosities, and laboured constantly and secretly in his chemical laboratory; so that he acquired the reputation of being a great alchemist, a philosopher studiously employed in the most useful and important researches. In 1766, he first publicly announced the object and nature of his secret labours:—all his discoveries centered in the magnet, which, according to his hypothesis, was the best and safest remedy hitherto proposed against all diseases incident to the human body.

This declaration of Messmer excited very general attention; the more so as about the same time he established a hospital in his own house, into which he admitted a number of patients gratis. Such disinterestedness procured, as might be expected, no small addition to his fame. He was, besides, fortunate in gaining over many celebrated physicians to his opinions, who lavished the greatest encomiums on his new art, and were instrumental in communicating to the public a number of successful experiments. This seems to have surpassed the expectations of Messmer, and induced him to extend his original plan further than it is likely he first intended. We find him soon after assuming a more dogmatical and mysterious air, when, for the purpose of shining exclusively, he appeared in the character of a magician:—his pride and egotism would brook neither equal nor competitor.

The common loadstone, or mineral magnet, which is so well known, did not appear to him sufficiently important and mysterious—he contrived an unusual one, to the effect of which he gave the name of 'animal magnetism'. After this, he proceeded to a still holder assumption, everywhere giving it out, that the inconceivable powers of this subtile fluid were centered in his own person. Now, the mona-drama began; and Messmer, at once the hero and chorus of the piece, performed his part in a masterly manner. He placed the most nervous, hysteric, and hypocondriac patients opposite to him; and by the sole act of stretching forth his finger, he made them feel the most violent shocks. The effects of this wonderful power excited universal astonishment; its activity and penetration being confirmed by unquestionable testimonies, from which it appeared, that blows similar to those given by a blunt iron, could be imparted by the operator, while he himself was separated by two doors, nay, even by thick walls. The very looks of this prince of jugglers had the power to excite painful cramps and twitches in his credulous and predisposed patients.

This wonderful tide of success instigated his indefatigable genius to bolder attempts, especially as he had no severe criticism to apprehend from the superstitious multitude. He roundly asserted things of which he offered not the least shadow of proof; and for the truth of which he had no other pledge to offer but his own high reputation. At one time he could communicate his magnetic power to paper, wool, silk, bread, leather, stones, water, etc., at another he asserted that certain individuals possessed a greater degree of susceptibility for this power than others. It must be owned, however, that many of his contemporaries made it their business to encounter his extravagant pretensions, and refute his dogmatical assertions with the most convincing arguments. Yet, he long enjoyed the triumph of being supported by blind followers, and their increasing number completely overpowered the suffrages of reason.

Messmer, at length perceived that in his native country, he should never be able to reach the point which he had fixed upon, as the termination of his magnetical career. The Germans began to discredit his pompous claims; but it was only after repeated failures in some promised cures, that he found himself under the necessity of seeking protection in Paris. There he met with a most flattering reception, being caressed, and in a manner adored by a nation which has always been extravagantly fond of every new thing, whimsical and mysterious. Messmer well knew how to turn this natural propensity to the best advantage. He addressed himself particularly to the weak; to such as wished to be considered men of profound knowledge, but who, when they were compelled to be silent from real ignorance, took refuge behind the impenetrable shield of mystery. The fashionable levity, the irresistible curiosity, and the peculiar turn of the Parisians, ever solicitous to have something interesting for conversation, to keep their active imagination in play, were exactly suited to the genius and talents of the inventor of animal magnetism. We need not wonder, therefore, if he availed himself of their moral and physical character, to ensure a ready faith in his doctrines, and success to his pretended experiments: in fact, he found friends and admirers wherever he made his appearance. His first advertisement was couched in the following high-sounding terms:

"Behold a discovery which promises unspeakable advantages to the human race, and immortal fame to its author! Behold the dawn of an universal revolution! A new race of men shall arise, shall overspread the earth, to embellish it by their virtues, and render it fertile by their industry. Neither vice nor ignorance, shall stop their active career; they will know our calamities only from the records of history. The prolonged duration of their life will enable them to plan and accomplish the most laudable undertakings. The tranquil, the innocent gratifications of that primeval age will be restored, wherein man laboured without toil, lived without sorrow, and expired without a groan! Mothers will no longer be subject to pain and danger during their pregnancy and child-birth: their progeny will be more robust and brave; the now rugged and difficult path of education will be rendered smooth and easy; and hereditary complaints and diseases will be for ever banished from the future auspicious race. Fathers rejoicing to see their posterity of the fourth and fifth generations, will only drop like fruit fully ripe, at the extreme point of age! Animals and plants, no less susceptible of the magnetic power than man, will be exempt from the reproach of barrenness and the ravages of distemper. The flocks in the fields, and the plants in the gardens, will be more vigorous and nourishing, and the trees will bear more beautiful and grateful fruits. The human race, once endowed with this elementary power, will probably rise to still more sublime and astonishing effects of nature: who indeed is able to pronounce, with certainty, how far this salutary influence may extend?"

"What splendid promises! What rich prospects! Messmer, the greatest of philosophers, the most virtuous of men, the physician of mankind, charitably opens his arms to all his fellow-mortals, who stand in need of comfort and assistance. No wonder that the cause of magnetism, under such a zealous apostle, rapidly gained ground, and obtained every day large additions to the number of its converts. To the gay, the nervous, and the dissipated of all ranks and ages, it held out the most flattering promises. Men of the first respectability interested themselves in behalf of this new philosophy; they anticipated in idea, the more happy and more vigorous race which would proceed, as it were, by enchantment, from the wonderful impulsive powers of animal magnetism. The French were so far seduced by these flattering appearances, as to offer the German adventurer thirty thousand livres for the communication of his secret art. He appears, however, to have understood his own interest better than thus to dispose of his hypothetical property, which, upon a more accurate investigation might be objected to, as consisting of unfair articles of purchase. He consequently returned the following answer to the credulous French ministers:

"That Dr. M. considered his art of too great importance, and the abuses it might lead to, too dangerous for him at present to make it public; that he must therefore reserve to himself the time of its publication, and mode of introducing it to general use and observation—that he would first take proper measures to initiate or prepare the minds of men, by exciting in them a susceptibility of this great power; and that he would then undertake to communicate his secret gradually, which he meant to do without hope of reward."

Messmer, too politic to part with his secret for so small a premium, had a better prospect in view; and his apparent disinterestedness and hesitation served only to sound an over-curious public, to allure more victims to his delusive practices, and to retain them more firmly in their implicit belief. Soon after this he was easily prevailed upon to institute a private society, into which none were admitted, but such as bound themselves by a vow to perpetual secrecy. These pupils he agreed to instruct in his important mysteries, on condition of each paying him one hundred louis. In the course of six months, having had not less than three hundred such pupils, he realized a fortune of thirty thousand louis.

It appears, however, that the disciples of Messmer did not adhere to their engagement: we find them separating gradually from their professor, and establishing schools for the propagation of his system, with a view, no doubt, to reimburse themselves for the expenses of their own initiation into the magnetising art. But few of them having understood the terms and mysterious doctrines of their foreign master, every new adept exerted himself to excel his fellow-labourers, in additional explanations and inventions: others, who did not possess, or could not spare the sum of one hundred louis, were industriously employed in attempts to discover the secret, by their own ingenuity; and thus arose a great variety of magnetical sects. At length, however, Messmer's authority became suspected; his pecuniary acquisitions were now notorious, and our humane and disinterested philosopher was assailed with critical and satirical animadversions from every quarter. The fertility of his process for medical purposes, as well as the bad consequences it might procure in a moral point of view, soon became topics of common conversation, and ultimately even excited the apprehensions of government. One dangerous effect of magnetical associations was, that young voluptuaries began to employ this art, to promote their libidinous and destructive designs.
