Chirology is the science of the hand: an experimental science based on observation and computation, whose aim is the interpretation and explanation of the lines and mounts of the palms and fingers, and of the exterior shape of the hand. Chirology is not an occult science: there is nothing supernatural, magical or diabolical about it: it has no mysteries. It is not a branch of the art of divination, for everybody may study and understand it. This work will help the reader become a chirologist and learn how to read the hand. Illustrated.
