The author of the work here quoted draws an interesting parallel between this organization and the modern traffic in cocaine, and goes on to describe the three degrees into which it was divided: firstly, the Heads, cultivated and intelligent men, who understood chemistry, physics, and nearly all useful sciences, "invisible counsellors but supreme, without whom the sorcerers and diviners would have been powerless"; secondly, the visible magicians employing mysterious processes, complicated rites and terrifying ceremonies; and thirdly, the crowd of nobles and plebeians who flocked to the doors of the sorcerers and filled their pockets in return for magic potions, philtres, and, in certain cases, insidious poisons. Thus La Voisin must be placed in the second category; "in spite of her luxury, her profits, and her fame," she "is only a subaltern agent in this vast organization of criminals. She depends entirely for her great enterprises on the intellectual chiefs of the corporation...."[261] Who were these intellectual chiefs? The man who first initiated Madame de Brinvilliers' lover Sainte-Croix into the art of poisoning was an Italian named Exili or Eggidi; but the real initiate from whom Eggidi and another Italian poisoner had learnt their secrets is said to have been Glaser, variously described as a German or a Swiss chemist, who followed the principles of Paracelsus and occupied the post of physician to the King and the Duc d'Orléans.[262] This man, about whose history little is known, might thus have been a kind of Rosicrucian. For since, as has been said, the intellectual chiefs from whom the poisoners derived their inspiration were men versed in chemistry, in science, in physics, and the treatment of diseases, and since, further, they included alchemists and people professing to be in possession of the Philosopher's Stone, their resemblance with the Rosicrucians is at once apparent. Indeed, in turning back to the branches of magic enumerated by the Rosicrucian Robert Fludd, we find not only Natural Magic, "that most occult and secret department of physics by which the mystical properties of natural substances are extracted," but also Venefic Magic, which "is familiar with potions, philtres, and with various preparations of poisons."
