The Bishop of Senes visited him in prison, and promised him his liberty if he would transmute a certain quantity of lead into gold before the King. The unhappy man had no longer the means of carrying on the deception; he had no gold, and no double-bottomed crucible or hollow wand to conceal it in, even if he had. He would not, however, confess that he was an impostor; but merely said he did not know how to make the powder of projection, but had received a quantity from an Italian philosopher, and had used it all in his various transmutations in Provence. He lingered for seven or eight months in the Bastille, and died from the effects of his wound, in the forty-first year of his age.

ALBERT ALUYS.

This pretender to the philosopher's stone, was the son, by a former husband, of the woman Aluys, with whom Delisle became acquainted at the commencement of his career, in the cabaret by the road side, and whom he afterwards married. Delisle performed the part of a father towards him, and thought he could show no stronger proof of his regard, than by giving him the necessary instructions to carry on the deception which had raised himself to such a pitch of greatness. The young Aluys was an apt scholar, and soon mastered all the jargon of the alchymists. He discoursed learnedly upon projections, cimentations, sublimations, the elixir of life, and the universal alkahest; and on the death of Delisle gave out that the secret of that great adept had been communicated to him, and to him only. His mother aided in the fraud, with the hope they might both fasten themselves, in the true alchymical fashion, upon some rich dupe, who would entertain them magnificently while the operation was in progress. The fate of Delisle was no inducement for them to stop in France. The Provencals, it is true, entertained as high an opinion as ever of his skill, and were well inclined to believe the tales of the young adept on whom his mantle had fallen; but the dungeons of the Bastille were yawning for their prey, and Aluys and his mother decamped with all convenient expedition. They travelled about the Continent for several years, sponging upon credulous rich men, and now and then performing successful transmutations by the aid of double-bottomed crucibles and the like. In the year 1726, Aluys, without his mother, who appears to have died in the interval, was at Vienna, where he introduced himself to the Duke de Richelieu, at that time ambassador from the court of France. He completely deceived this nobleman; he turned lead into gold (apparently) on several occasions, and even made the ambassador himself turn an iron nail into a silver one. The Duke afterwards boasted to Lenglet du Fresnoy of his achievements as an alchymist, and regretted that he had not been able to discover the secret of the precious powder by which he performed them.

Aluys soon found that, although he might make a dupe of the Duke de Richelieu, he could not get any money from him. On the contrary, the Duke expected all his pokers and fire shovels to be made silver, and all his pewter utensils gold; and thought the honour of his acquaintance was reward sufficient for a roturier, who could not want wealth since he possessed so invaluable a secret. Aluys seeing that so much was expected of him, bade adieu to his Excellency, and proceeded to Bohemia, accompanied by a pupil, and by a young girl who had fallen in love with him in Vienna. Some noblemen in Bohemia received him kindly, and entertained him at their houses for months at a time. It was his usual practice to pretend that he possessed only a few grains of his powder, with which he would operate in any house where he intended to fix his quarters for the season. He would make the proprietor a present of the piece of gold thus transmuted, and promise him millions, if he could only be provided with leisure to gather his lunaria major and minor on their mountain tops, and board, lodging, and loose cash for himself, his wife, and his pupil in the interval.

He exhausted in this manner the patience of some dozen of people, when, thinking that there was less danger for him in France, under the young king Louis XV, than under his old and morose predecessor, he returned to Provence. On his arrival at Aix, he presented himself before M. le Bret, the President of the province, a gentleman who was much attached to the pursuits of alchymy, and had great hopes of being himself able to find the philosopher's stone. M. le Bret, contrary to his expectation, received him very coolly, in consequence of some rumours that were spread abroad respecting him; and told him to call upon him on the morrow. Aluys did not like the tone of the voice, or the expression of the eye of the learned President, as that functionary looked down upon him. Suspecting that all was not right, he left Aix secretly the same evening, and proceeded to Marseilles. But the police were on the watch for him; and he had not been there four-and-twenty hours, before he was arrested on a charge of coining, and thrown into prison.

As the proofs against him were too convincing to leave him much hope of an acquittal, he planned an escape from durance. It so happened that the gaoler had a pretty daughter, and Aluys soon discovered that she was tender-hearted. He endeavoured to gain her in his favour, and succeeded. The damsel, unaware that he was a married man, conceived and encouraged a passion for him, and generously provided him with the means of escape. After he had been nearly a year in prison he succeeded in getting free, leaving the poor girl behind, to learn that he was already married, and to lament in solitude that she had given her heart to an ungrateful vagabond.

When he left Marseilles, he had not a shoe to his foot, or a decent garment to his back, but was provided with some money and clothes by his wife in a neighbouring town. They then found their way to Brussels, and by dint of excessive impudence, brought themselves into notice. He took a house, fitted up a splendid laboratory, and gave out that he knew the secret of transmutation. In vain did M. Percel, the brother-in-law of Lenglet du Fresnoy, who resided in that city, expose his pretensions, and hold him up to contempt as an ignorant impostor: the world believed him not. They took the alchymist at his word, and besieged his doors, to see and wonder at the clever legerdemain by which he turned iron nails into gold and silver. A rich greffier paid him a large sum of money that he might be instructed in the art, and Aluys gave him several lessons on the most common principles of chemistry. The greffier studied hard for a twelvemonth, and then discovered that his master was a quack. He demanded his money back again; but Aluys was not inclined to give it him, and the affair was brought before the civil tribunal of the province. In the mean time, however, the greffier died suddenly; poisoned, according to the popular rumour, by his debtor, to avoid repayment. So great an outcry arose in the city, that Aluys, who may have been innocent of the crime, was nevertheless afraid to remain and brave it. He withdrew secretly in the night, and retired to Paris. Here all trace of him is lost. He was never heard of again; but Lenglet du Fresnoy conjectures, that he ended his days in some obscure dungeon, into which he was cast for coining, or other malpractices.

THE COUNT DE ST. GERMAIN

This adventurer was of a higher grade than the last, and played a distinguished part at the court of Louis XV. He pretended to have discovered the elixir of life, by means of which he could make any one live for centuries; and allowed it to be believed that his own age was upwards of two thousand years. He entertained many of the opinions of the Rosicrucians; boasted of his intercourse with sylphs and salamanders; and of his power of drawing diamonds from the earth, and pearls from the sea, by the force of his incantations. He did not lay claim to the merit of having discovered the philosopher's stone; but devoted so much of his time to the operations of alchymy, that it was very generally believed, that, if such a thing as the philosopher's stone had ever existed, or could be called into existence, he was the man to succeed in finding it.

It has never yet been discovered what was his real name, or in what country he was born. Some believed, from the Jewish cast of his handsome countenance, that he was the "wandering Jew;" others asserted, that he was the issue of an Arabian princess, and that his father was a salamander; while others, more reasonable, affirmed him to be the son of a Portuguese Jew, established at Bourdeaux. He first carried on his imposture in Germany, where he made considerable sums by selling an elixir to arrest the progress of old age. The Marechal de Belle-Isle purchased a dose of it; and was so captivated with the wit, learning, and good manners of the charlatan, and so convinced of the justice of his most preposterous pretensions, that he induced him to fix his residence in Paris. Under the Marshal's patronage, he first appeared in the gay circles of that capital. Every one was delighted with the mysterious stranger; who, at this period of his life, appears to have been about seventy years of age, but did not look more than forty-five. His easy assurance imposed upon most people. His reading was extensive, and his memory extraordinarily tenacious of the slightest circumstances. His pretension to have lived for so many centuries naturally exposed him to some puzzling questions, as to the appearance, life, and conversation of the great men of former days; but he was never at a loss for an answer. Many who questioned him for the purpose of scoffing at him, refrained in perplexity, quite bewildered by his presence of mind, his ready replies, and his astonishing accuracy on every point mentioned in history. To increase the mystery by which he was surrounded, he permitted no person to know how he lived. He dressed in a style of the greatest magnificence; sported valuable diamonds in his hat, on his fingers, and in his shoe-buckles; and sometimes made the most costly presents to the ladies of the court. It was suspected by many that he was a spy, in the pay of the English ministry; but there never was a tittle of evidence to support the charge. The King looked upon him with marked favour, was often closeted with him for hours together, and would not suffer anybody to speak disparagingly of him. Voltaire constantly turned him into ridicule; and, in one of his letters to the King of Prussia, mentions him as "un comte pour fire;" and states, that he pretended to have dined with the holy fathers, at the Council of Trent!
