Bötticher remained in confinement with every opportunity to manufacture the philosophical stone, which, however he failed to accomplish; but what with his apothecary’s training and his prison experiments, he had become skilled in several departments of chemistry. He discovered the process for the production of red porcelain, and afterwards that of white, very superior in quality to the substances already known by that name. These inventions proved as valuable to the tyrannical Elector as the accomplishment of the _magnum opus_. Bötticher was restored to his favour, and again enjoyed his baronial title, but in his liberty he surrendered himself to an immoderately luxurious life, and died in 1719 at the age of thirty-seven years. Bötticher was by no means the only apothecary’s boy who was enriched with the powder of Lascaris, and despatched to preach the gospel of alchemy with practical demonstrations. Godwin, Hermann, Braun, and Martin of Fitzlar are mentioned among these half-initiated labourers, who shone till their stock-in-trade was exhausted, and then disappeared in succession. In the meantime, Lascaris himself was not idle. On the 16th February 1609 he is believed to have changed mercury into gold and gold into silver, a double transmutation, considered by alchemical connoisseurs to be the evidence of an unparalleled adeptship. Liebkneck, counsellor of Wertherbourg, was a witness of this transmutation. In the same year a goldsmith of Leipsic was visited by a mysterious stranger, who is unanimously identified with Lascaris, and who showed him a lingot, which he declared was manufactured by art, and which proved in assaying to be gold of twenty-two carats. It was purified by the goldsmith with antimony, and part of it was presented to him by the unknown as a memorial of the alleged transmutation. Shortly after, a lieutenant-colonel in the Polish army, whose name was Schmolz de Dierbach, and who had inherited from his father a belief in alchemical science, was conversing on the subject at a café, when he was accosted by a stranger, who presented him with some powder of projection. It was of a red colour, and a microscopic examination revealed its crystalline nature. It increased the weight of the metals which it was supposed to transmute to an extent which chemical authorities declare to be physically impossible. The recipient made use of it generously, distributing to his friends and acquaintance the gold it produced in projection. The unknown donor is identified in the imagination of German historians with the mysterious Lascaris, who is supposed, in the same anonymous and unaccountable manner, to have enriched the Baron de Creux with a box of the precious powder, and to have gratified the amateur Hermetic ambition of the Landgrave of Hesse Darmstadt through the commonplace medium of the post. In a word, every anonymous adept who appeared at this period in or about Germany is supposed to be Lascaris.
