Sardius
This gem resembles the cornelian, and is an antidote to the onyx. It prevents unpleasant dreams, makes its possessor wealthy, and sharpens the wit.
Sardou, Victorian: The famous French dramatist was a keen student of occultism, and studied spiritualism with Allan Kardec (q.v.). He achieved great facility as a medium for spirit drawings, and many of the examples by his hand are of great merit artistically as well as from an occult point of view. Some of them are reproduced in M. Camille Flammarion's book Mysterious Psychic Forces. (See France.)
