was to procure him wealth to cheer him in his multiplicity of days. He published a small treatise upon the subject at Cologne, in 1531, which obtained him the patronage of the celebrated Maurice duke of Saxony. After practising for some years as a physician at Joachimsthal, in Bohemia, he was employed by Maurice as superintendent of the silver mines of Chemnitz. He led a happy life among the miners, making various experiments in alchymy while deep in the bowels of the earth. He acquired a great knowledge of metals, and gradually got rid of his extravagant notions about the philosopher's stone. The miners had no faith in alchymy; and they converted him to their way of thinking, not only in that but in other respects. From their legends, he became firmly convinced that the bowels of the earth were inhabited by good and evil spirits, and that firedamp and other explosions sprang from no other causes than the mischievous propensities of the latter. He died in the year 1555, leaving behind him the reputation of a very able and intelligent man.
Denis Zachaire.
Autobiography, written by a wise man who was once a fool, is not only the most instructive, but the most delightful of reading. Denis Zachaire, an alchymist of the sixteenth century, has performed this task, and left a record of his folly and infatuation in pursuit of the philosopher's stone, which well repays perusal. He was born in the year 1510, of an ancient family in Guienne, and was early sent to the university of Bordeaux, under the care of a tutor to direct his studies. Unfortunately his tutor was a searcher for the grand elixir, and soon rendered his pupil as mad as himself upon the subject. With this introduction, we will allow Denis Zachaire to speak for himself, and continue his narrative in his own words: "I received from home," says he, "the sum of two hundred crowns for the expenses of myself and master; but before the end of the year, all our money went away in the smoke of our furnaces. My master, at the same time, died of a fever, brought on by the parching heat of our laboratory, from which he seldom or never stirred, and which was scarcely less hot than the arsenal of Venice. His death was the more unfortunate for me, as my parents took the opportunity of reducing my allowance, and sending me only sufficient for my board and lodging, instead of the sum I required to continue my operations in alchymy.
"To meet this difficulty and get out of leading-strings, I returned home at the age of twenty-five, and mortgaged part of my property for four hundred crowns. This sum was necessary to perform an operation of the science, which had been communicated to me by an
