Let us not, in the pride of our superior knowledge, turn with contempt from the follies of our predecessors. The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive. As the man looks back to the days of his childhood and his youth, and recalls to his mind the strange notions and false opinions that swayed his actions at that time, that he may wonder at them, so should society, for its edification, look back to the opinions which governed the ages fled. He is but a superficial thinker who would despise and refuse to hear of them merely because they are absurd. No man is so wise but that he may learn some wisdom from his past errors, either of thought or action, and no society has made such advances as to be capable of no improvement from the retrospect of its past folly and credulity. And not only is such a study instructive: he who reads for amusement only, will find no chapter in the annals of the human mind more amusing than this. It opens out the whole realm of fiction — the wild, the fantastic, and the wonderful, and all the immense variety of things “that are not, and cannot be; but that have been imagined and believed.”

For more than a thousand years the art of alchymy captivated many noble spirits, and was believed in by millions. Its origin is involved in obscurity. Some of its devotees have claimed for it an antiquity coeval with the creation of man himself; others, again, would trace it no further back than the time of Noah. Vincent de Beauvais argues, indeed, that all the antediluvians must have possessed a knowledge of alchymy; and particularly cites Noah as having been acquainted with the elixir vit&oelig, or he could not have lived to so prodigious an age, and have begotten children when upwards of five hundred. Lenglet du Fresnoy, in his History of the Hermetic Philosophy, says, “Most of them pretended that Shem, or Chem, the son of Noah, was an adept in the art, and thought it highly probable that the words chemistry and alchymy were both derived from his name.” Others say, the art was derived from the Egyptians, amongst whom it was first founded by Hermes Trismegistus. Moses, who is looked upon as a first-rate alchymist, gained his knowledge in Egypt; but he kept it all to himself, and would not instruct the children of Israel in its mysteries. All the writers upon alchymy triumphantly cite the story of the golden calf, in the 32nd chapter of Exodus, to prove that this great lawgiver was an adept, and could make or unmake gold at his pleasure. It is recorded, that Moses was so wroth with the Israelites for their idolatry, “that he took the calf which they had made, and burned it in the fire, and ground it to powder, and strewed it upon the water, and made the children of Israel drink of it.” This, say the alchymists, he never could have done, had he not been in possession of the philosopher’s stone; by no other means could he have made the powder of gold float upon the water. But we must leave this knotty point for the consideration of the adepts in the art, if any such there be, and come to more modern periods of its history. The Jesuit, Father Martini, in his Historia Sinica, says, it was practised by the Chinese two thousand five hundred years before the birth of Christ; but his assertion, being unsupported, is worth nothing. It would appear, however, that pretenders to the art of making gold and silver existed in Rome in the first centuries after the Christian era, and that, when discovered, they were liable to punishment as knaves and impostors. At Constantinople, in the fourth century, the transmutation of metals was very generally believed in, and many of the Greek ecclesiastics wrote treatises upon the subject. Their names are preserved, and some notice of their works given, in the third volume of Lenglet du Fresnoy’s History of the Hermetic Philosophy.s Their notion appears to have been, that all metals were composed of two substances; the one, metallic earth; and the other, a red inflammable matter, which they called sulphur. The pure union of these substances formed gold; but other metals were mixed with and contaminated by various foreign ingredients. The object of the philosopher’s stone was to dissolve or neutralize all these ingredients, by which iron, lead, copper, and all metals would be transmuted into the original gold. Many learned and clever men wasted their time, their health, and their energies, in this vain pursuit; but for several centuries it took no great hold upon the imagination of the people. The history of the delusion appears, in a manner, lost from this time till the eighth century, when it appeared amongst the Arabians. From this period it becomes easier to trace its progress. A master then appeared, who was long looked upon as the father of the science, and whose name is indissolubly connected with it.

    Of this philosopher, who devoted his life to the study of alchymy, but few particulars are known. He is thought to have lived in the year 730. His true name was Abou Moussah Djafar, to which was added
