"In the large curative establishment founded by Mesmer at Vienna, he employed, besides magnetism, electricity, metals and a variety of woods. His fundamental doctrine was that of the Alchemists. He believed that metals, as also woods and plants have all an affinity with and bear a close relation to, the human organism. Everything in the Universe has developed from one homogeneous primordial substance differentiated into incalculable species of matter, and everything is destined to return thereinto."
