Occult Chemistry

Annie Besant, Charles Webster Leadbeater

The Periodic Law: the number affixed to an element is the number of "Anu" (the ultimate physical particles of which matter is constituted). Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds (originally subtitled A Series of Clairvoyant Observations on the Chemical Elements) is a book written by Annie Besant and C.W. Leadbeater, who were all members of the Theosophical Society based in Adyar, India. Besant was at the time the President of the Society having succeeded Henry Olcott after his death in 1907.
