How to preform old séances?
Do you intend to rebuild those seances--as in preform them? If you meant to p e r f o r m them, then that is a question for the mystifiers.
You need to be more specific. Are you trying to write about how séances were done, or enact one in a play? Any book on the history of spiritualism or on mediums' tricks will tell you the usual routines. Most of them require special equipment to produce the effects.
