In this book, Dr. Lisiewski reveals the role Dr. Israel Regardie played in the world of Practical Laboratory Alchemy. Not the world of idle speculation and so-called inner alchemy, but the realm of the test tube and the Soxhlet Extractor. Revealed for the first time are Regardie's own private alchemical experiments, his intense interaction with Frater Albertus of the Paracelsus Research Society, and later, with the author himself. You will learn of the first meeting between Regardie and Frater Albertus; their involvement with the Rosicrucian Order; their years of struggle in Alchemy; and the alchemical work they and the author explored. Such work includes preparation of the Ancient Planetary and Antimony Tinctures, the Herbal Stone, and the darkly fantastic processes of miniature animals and the Homunculus. Israel Regardie & The Philosopher's Stone is the definitive work on Israel Regardie's virtually unknown role in the practice of the Secret Art and Science that is Laboratory Alchemy, while revealing processes in the practical application of this occult work that have never appeared in print before!
