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 Langlet du Fresnoy's History of the Hermetic Philosophy. 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 neutralise 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 Al Sofi, or "The Wise," and he was born at Houran, in Mesopotamia.[1] Some have thought he was a Greek, others a Spaniard, and others a prince of Hindostan; but of all the mistakes which have been made respecting him, the most ludicrous was that made by the French translator of Sprenger's History of Medicine, who thought,
