Occult Chemistry-Clairvoyant Observations on the Chemical Elements is a classic occult science text by Annie Besant. It remains to be seen--not how far, but rather how soon the scientific world at large will accept the conclusions of this volume of Occult Chemistry as a definite contribution to science, blending the science of the laboratory with that variety that has hitherto been called occult. The first edition was published in 1908, the second edition in 1919, and a third in 1951. Since the first edition was published in 1908, the book is in the public domain, and available in whole or in excerpts, on many sites on the internet. Occult Chemistry states that the structure of chemical elements can be assessed through clairvoyant observation with the microscopic vision of the third eye. Observations were carried out between 1895 and 1933. "The book consists both of coordinated and illustrated descriptions of presumed etheric counterparts of the atoms of the then known chemical elements, and of other expositions of occult physics.
