Kempelen; but I have thought that even these few details would have interest for the public.
There can be little question that most of the marvellous rumors afloat about this affair, are pure inventions, entitled to about as much credit as the story of Aladdin's lamp; and yet, in a case of this kind, as in the case of the discoveries in California, it is clear that the truth may be stranger than fiction. The following anecdote, at least, is so well authenticated, that we may receive it implicitly.
Von Kempelen had never been even tolerably well off during his residence at Bremen; and often, it was well known, he had been put to extreme shifts, in order to raise trifling sums. When the great excitement occurred about the forgery on the house of Gutsmuth & Co., suspicion was directed towards Von Kempelen, on account of his having purchased a considerable property in Gasperitch Lane, and his refusing, when questioned, to explain how he became possessed of the purchase money. He was at length arrested, but nothing decisive appearing against him, was in the end set at liberty. The police, however, kept a strict watch upon his movements, and thus discovered that he left home frequently, taking always the same road, and invariably giving his watchers the slip in the neighborhood of that labyrinth of narrow and
crooked passages known by the flash-name of the “Dondergat." / Finally, by dint of great perseverance, they traced him to a garret
in an old house of seven stories, in an alley called Flätplatz; and, coming upon him suddenly, found him, as they imagined, in the midst of his counterfeiting operations. His agitation is represented as so excessive that the officers had not the slightest doubt of his guilt. After hand-cuffing him, they searched his room, or rather rooms; for it appears he occupied all the mausarde.
Opening into the garret where they caught him, was a closet, ten feet by eight, fitted up with some chemical apparatus, of which the object has not yet been ascertained. In one corner of the closet was a very small furnace, with a glowing fire in it, and on the fire a kind of duplicate crucible—two crucibles connected by a tube. One of these crucibles was nearly full of lead in a state of fusion, but not reaching up to the aperture of the tube, which was close to the brim. The other crucible had some liquid in it,
which, as the officers entered, seemed to be furiously dissipating in vapor. They relate that, on finding himself taken, Von Kempelen seized the crucibles with both hands (which were encased in gloves that afterwards turned out to be asbestic), and threw the contents on the tiled floor. It was now that they hand-cuffed him; and, before proceeding to ransack the premises, they searched his person, but nothing unusual was found about him, excepting a paper parcel, in his coat pocket, containing what was afterwards ascertained to be a mixture of antimony and some unknown substance, in nearly, but not quite, equal proportions. All attempts at analyzing the unknown substance have, so far, failed, but that it will ultimately be analyzed, is not to be doubted.
Passing out of the closet with their prisoner, the officers went through a sort of ante-chamber, in which nothing material was · found, to the chemist's sleeping-room. They here rummaged
some drawers and boxes, but discovered only a few papers, of no importance, and some good coin, silver and gold. At length, looking under the bed, they saw a large, common hair trunk, without hinges, hasp, or lock, and with the top lying carelessly across the bottom portion. Upon attempting to draw this trunk out from under the bed, they found that, with their united strength (there were three of them, all powerful men), they could not stir it one inch.” Much astonished at this, one of them crawled under the bed, and looking into the trunk, said:
“No wonder we couldn't move it—why, it's full to the brim of , old bits of brass !”
Putting his feet, now, against the wall, so as to get a good purchase, and pushing with all his force, while his companions pulled with all theirs, the trunk, with much difficulty, 'was slid out from under the bed, and its contents examined. The supposed brass with which it was filled was all in small, smooth pieces, varying from the size of a pea to that of a dollar; but the pieces were irregular in shape, although all more or less flat-looking, upon the whole,“ very much as lead looks when thrown upon the ground in a molten state, and there suffered to grow cool.” Now, not one of these officers for a moment suspected this metal to be anything but brass. The idea of its being gold never entered their brains, of course; how could such a wild fancy have entered it ? And their astonishment may be well conceived, when next day it became known, all over Bremen, that the “lot of brass” which they had carted so contemptuously to the police office, without putting themselves to the trouble of pocketing the smallest scrap, was not only gold-real gold—but gold far finer than any employed in coinage-gold, in fact, absolutely pure, virgin, without the slightest appreciable alloy!
I need not go over the details of Von Kempelen's confession (as far as it went) and release, for these are familiar to the public. That he has actually realized, in spirit and in effect, if not to the letter, the old chimera of the philosopher's stone, no sane person is at liberty to doubt. The opinions of Arago are, of course, entitled to the greatest consideration; but he is by no means infallible; and what he says of bismuth, in his teport to the academy, must be taken cum grano salis. The simple truth is, that up to this period, all analysis has failed; and until Von Kempelen chooses to let us have the key to his own published enigma, it is more than probable that the matter will remain, for years, in statu quo. All that yet can fairly be said to be known, is, that “pure gold can be made at will, and very readily, from lead, in connection with certain other substances, in kind and in proportions, unknown.”
Speculation, of course, is busy as to the immediate and ultimate results of this discovery-a discovery which few thinking persons will hesitate in referring to an increased interest in the matter of gold generally, by the late developments in California; and this reflection brings us inevitably to another—the exceeding inopportuneness of Von Kempelen's analysis. If many were prevented from adventuring to California, by the mere apprehension that gold would so materially diminish in value, on account of its plentifulness in the mines there, as to render the speculation of going so far in search of it a doubtful one-what impression will be wrought now, upon the minds of those about to emigrate, and especially upon the minds of those actually in the mineral region, by the announcement of this astounding discovery of Von Kempelen? a discovery which declares, in so many words, that beyond its intrinsic worth for manufacturing purposes, (whatever that worth may be), gold now is, or at least soon will be (for it cannot be supposed that Von Kempelen can long retain his secret) of no greater value than lead, and of far inferior value to silver, It is indeed, exceedingly difficult to speculate prospectively upon the consequences of the discovery ; but one thing may be positively maintained—that the announcement of the discovery six months ago, would have had material influence in regard to the settlement of California.
In Europe, as yet, the most noticeable results have been a rise of two hundred per cent. in the price of lead, and nearly twentyfive cent. in that of silver.
WHATEVER doubt may still envelop the rationale of mesmerism, its startling facts are now almost universally admitted. Of these latter, those who doubt, are your mere doubters by professionan unprofitable and disreputable tribe. There can be no more absolute waste of time than the attempt to prove, at the present day, that man, by mere exercise of will, can so impress his fel. low, as to cast him into an abnormal condition, of which the phenomena reseñble very closely those of death, or at least re. semble them more nearly than they do the phenomena of any other normal condition within our cognizance; that, while in this state, the person so impressed employs only with effort, and then feebly, the external organs of sense, yet perceives, with keenly refined perception, and through channels supposed unknown, matters beyond the scope of the physical organs; that, moreover, his intellectual faculties are wonderfully exalted and invigorated ; that his sympathies with the person so impressing him are profound ; and, finally, that his susceptibility to the impression increases with its frequency, while, in the same proportion, the peculiar phenomena elicited are more extended and more pronounced.
I say that these—which are the laws of mesmerism in its general features—it would be supererogation to demonstrate ; nor shall I inflict upon my readers so needless a demonstration to-day. My purpose at present is a very different one indeed. I am impelled, even in the teeth of a world of prejudice, to detail without com. ment the very remarkable substance of a colloquy, occurring between a sleep-waker and myself. I had been long in the habit of mesmerizing the person
