Frederic Myers like all of Piper's controls failed to prove his identity.

Mediumship is the pseudoscientific practice of mediating communication between familiar spirits or spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums". There are different types of mediumship or spirit channelling, including séance tables, trance, and ouija. The practice is associated with spiritualism and spiritism. A similar New Age practice is known as channeling.
