Memoirs of Extraordinary Popular Delusions-3 [62]
by him; together with a Memoir of his Life." This book contained a complete exposition of the Rosicrucian philosophy, and afforded materials to the Abbe de Villars for his interesting "Count de Gabalis," which excited so much attention at the close of the seventeenth century.
Borri lingered in the prison of St. Angelo till 1695, when he died in his eightieth year. Besides "The Key of the Cabinet," written originally in Copenhagen, in 1666, for the edification of King Frederic III, he published a work upon alchymy and the secret sciences, under the title of "The Mission of Romulus to the Romans."
INFERIOR ALCHYMISTS OF THE SEVENTEENTH CENTURY.
Besides the pretenders to the philosopher's stone whose lives have been already narrated, this and the preceding century produced a great number of writers, who inundated literature with their books upon the subject. In fact, most of the learned men of that age had some faith in it. Van Helmont, Borrichius, Kirchen, Boerhaave, and a score of others, though not professed alchymists, were fond of the science, and countenanced its professors. Helvetius, the grandfather of the celebrated philosopher of the same name, asserts that he saw an inferior metal turned into gold by a stranger, at the Hague, in 1666. He says that, sitting one day in his study, a man, who was dressed as a respectable burgher of North Holland, and very modest and simple in his appearance, called upon him, with the intention of dispelling his doubts relative to the philosopher's stone. He asked Helvetius if he thought he should know that rare gem if he saw it. To which Helvetius replied, that he certainly should not. The burgher immediately drew from his pocket a small ivory box, containing three pieces of metal, of the colour of brimstone, and extremely heavy; and assured Helvetius, that of them he could make as much as twenty tons of gold. Helvetius informs us, that he examined them very attentively; and seeing that they were very brittle, he took the opportunity to scrape off a very small portion with his thumb-nail. He then returned them to the stranger, with an entreaty that he would perform the process of transmutation before him. The stranger replied, that he was not allowed to do so, and went away. After his departure, Helvetius procured a crucible and a portion of lead, into which, when in a state of fusion, he threw the stolen grain from the philosopher's stone. He was disappointed to find that the grain evaporated altogether, leaving the lead in its original state.
Some weeks afterwards, when he had almost forgotten the subject, he received another visit from the stranger. He again entreated him to explain the processes by which he pretended to transmute lead. The stranger at last consented, and informed him, that one grain was sufficient; but that it was necessary to envelope it in a ball of wax before throwing it on the molten metal; otherwise its extreme volatility would cause it to go off in vapour. They tried the experiment, and succeeded to their heart's content. Helvetius repeated the experiment alone, and converted six ounces of lead into very pure gold.
The fame of this event spread all over the Hague, and all the notable persons of the town flocked to the study of Helvetius to convince themselves of the fact. Helvetius performed the experiment again, in the presence of the Prince of Orange, and several times afterwards, until he exhausted the whole of the powder he had received from the stranger, from whom, it is necessary to state, he never received another visit; nor did he ever discover his name or condition. In the following year Helvetius published his "Golden Calf," ["Vitulus Aureus quem Mundus adorat et orat, in quo tractatur de naturae miraculo transmutandi metalla."--Hagae, 1667.] in which he detailed the above circumstances.
About the same time, the celebrated Father Kircher published his "Subterranean World," in which he called the alchymists a congregation of knaves and impostors, and their science a delusion. He admitted that he had
