The psychical researchers Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled Revelations of a Spirit Medium (1922) which exposed the tricks of mediumship and the fraudulent methods of producing "spirit hands".[132] Originally all the copies of the book were bought up by spiritualists and deliberately destroyed.[133] In 1923, the magician Carlos María de Heredia revealed how fake spirit hands could be made by using a rubber glove, paraffin and a jar of cold water.[134]
The poet Robert Browning and his wife Elizabeth attended a séance on 23, July 1855 in Ealing with the Rymers.[64] During the séance a spirit face materialized which Home claimed was the son of Browning who had died in infancy. Browning seized the "materialization" and discovered it to be the bare foot of Home. To make the deception worse, Browning had never lost a son in infancy. Browning's son Robert in a letter to The Times, December 5, 1902 referred to the incident "Home was detected in a vulgar fraud."[65][66] The researchers Joseph McCabe and Trevor H. Hall exposed the "levitation" of Home as nothing more than his moving across a connecting ledge between two iron balconies.[67]

Like common playing cards, the tarot has four suits (which vary by region: French suits in Northern Europe, Latin suits in Southern Europe, and German suits in Central Europe). Each suit has 14 cards, ten pip cards numbering from one (or Ace) to ten and four face cards (King, Queen, Knight, and Jack/Knave). In addition, the tarot has a separate 21-card trump suit and a single card known as the Fool. Depending on the game, the Fool may act as the top trump or may be played to avoid following suit.[1] These tarot cards, without occult symbology, are still used throughout much of Europe to play card games.
