“We have a ready and palpable proof of such possibilities. A foreign correspondent of the Theosophical Society, a well-known medical practitioner, and one who has studied the occult sciences for upward of thirty years, has succeeded in obtaining what he terms the “true oil of gold”, i.e., the primal element. Chemists and physicists have seen and examined it, and were driven to confess that they neither knew how it was obtained nor could they do the same.
That he desires his name to remain unknown is not to be wondered at; ridicule and pubic prejudice are more dangerous sometimes than the inquisition of old. This “Adamic earth” is next-door neighbor to the alkahest, and one of the most important secrets of the alchemists.
No Kabalist will reveal it to the world, for, as he expresses it in the well-known jargon: “it would explain the eagles of the alchemists, and how the eagles’ wings are clipped”, a secret that it took Thomas Vaughan (Eugenius Philalethes) twenty years to learn.”
