Physical Mediumship

Physical mediumship is the séance's physical side: phenomena produced in the room, the raps and the table tilting and the apports and the trumpet voices and the materialized figures, the ectoplasm the Victorian era named for the gauzelike substance said to exude from the medium's body and to disintegrate in light, the dark room requirement born of that doctrine and the fraud it sheltered in equal measure. The tradition's founding is the raps of 1848, and its golden age supplied the phenomena's most famous cases: the Scottish American whose levitations and accordion playings were investigated by the chemist with spring balances and never caught cheating, often in good light; the Italian whose favorable sittings with the era's luminaries alternated with exposures in Cambridge and America, the Naples report's four hundred catalogued occurrences endorsed and the follow-up's failure ascribed to fraud; and the English girl whose materialized control was seized by a sitter who broke the circle's agreement, the chemist's controlled sittings endorsing her while the allegations persisted.

The practice's apparatus is specific: the cabinet, the curtained recess the medium sits in, the hands and forms emerging from its curtain while the sitters hold the medium's hands and feet; the light conditions, moonlight preferred by the chemist, glowworm-lit sittings reported from Brazil, the red lamps the twentieth century standardized; and the circle's etiquette itself evidentiary, the agreement's breach dismissing the grab that exposed the materialized figure. The decline is the record's spine: the Society's exposure catalogue, the trick manual whose republication the Spiritualists bought up and destroyed, the Boston medium's ectoplasmic hand shown to be carved animal liver, the magician's crusade and its book, and the Scottish medium jailed in 1944 under the Witchcraft Act after the warship's séance, her ectoplasm shown to be cheesecloth. The practice retreated to the churches and the home circles, and its modern revival is small and contested: the Norfolk circle whose cellar sittings and photographic anomalies drew the Society's full-length report concluding the phenomena genuine while its critics said verification was impossible, the lights replicable with rods and thread, the photographic extras matched to published sources, the doubters excluded; the German group whose strip searches and four-limb controls accompanied a documented trick behind the moving lights and a tacit confession that public demonstrations differ from controlled sittings, the investigator judging most phenomena probably fraudulent; the Australian direct-voice circle's paid weeks abroad; and the Brazilian spiritism that recognizes the physical-effects medium as a category, its contemporary literature extensive in Portuguese.

The market is small: the Norfolk circle's fifty-pound sittings, the church demonstrations' few pounds, the novelty séance's hundreds, and the paid development weeks forming the niche's economy. Access is open, no certification gate. The entry's counsel is the record's: the phenomena claimed are physical and therefore testable, and a century and a half of testing has found the apparatus behind nearly every famous case, the honest practitioner's modern standard being the strip search and the controlled sitting, and the honest reader's being the history itself.
