The life of Denis Zachaire has been made the subject of an interesting and well-written novel--“A Professor of Alchemy”--by “Percy Ross,” recently published by Mr George Redway. The life of the great adept, after his accomplishment of the Magnum Opus, is detailed at some length, M. Louis Figuier being apparently the authority for the bare facts of the case. The alchemist is represented by the French writer as having travelled to Lausanne, where he became enamoured of a young and beautiful lady, whom he carried from Switzerland into Germany, and then abandoned himself completely to a life of dissipation and folly, which closed tragically at Cologne in the year 1556. He was strangled in the middle of a drunken sleep by the cousin who had accompanied him in his travels, and who coveted his wealth and his mistress.

The manuscript volume entitled “Egyptian Freemasonry” fell, with the other papers of Cagliostro, into the hands of the Inquisition, and was solemnly condemned in the judgment as containing rites, propositions, a doctrine and a system which opened a broad road to sedition and were calculated to destroy the Christian religion. The book was characterised as superstitious, blasphemous, impious, and heretical. It was publicly burnt by the hands of the executioner, with the instruments belonging to the sect. Some valuable particulars concerning it are, however, preserved in the Italian life; they are reproduced from the original proceedings published at Rome by order of the Apostolic Chamber.
