UMBRATILES
Text: Shadows; astral appearances becoming visible and sometimes tangible (modern spiritualistic form manifestations); the Scin-lecca, or wraith, or the German Doppelgaenger of a person. They may become visible by attracting ethereal material elements from the body of a medium, or any other person in whom there is little cohesion of his lower elements in consequence of some diseases, or on account of inherited peculiarities of his organization; or they may attract them from the surrounding atmosphere. Their life is borrowed from the medium, and if it were prevented to return to the medium, the latter would be paralyzed or die.
