Pure electography of the hand by Iodko's method. The hand of an over-electrified person, placed on a plate gives a very remarkable impression of the electrified cutaneous surface. One can here easily note the difference between electrography and iconography, where the vital waves are produced by themselves and are graphed by themselves without electricity.

In The Human Soul: Its Movements, Its Lights, and the Iconography of the Fluidic Invisible, originally published in French in 1896, Dr. Hippolyte Baraduc (1850–1909) postulates the existence of “the fluidic invisible” — a “vital cosmic force”, which he calls Odic liquid, that extends across the universe and “saturates the organism of living beings and constitutes our fluidic body”. Instead of all things being composed of one elementary substance, as in philosophical accounts of the monad, in this cosmic vision, we all live in a sea that we cannot see, which Baraduc names Somod.
