The turning of spirit into psychical matter was a favourite phenomenon of the Spiritualists, not least because it gave empirical weight to the claims of the continued existence of the departed spirits. From a s茅ance cabinet, typically restrained, the spirit voices in a s茅ance would solidify, either as a person, or through a sheet of material or paper cut-out.
Materialisation
The restraint of mediums to prevent any falsification, as well as strip or even cavity searches, often resulted in somewhat weaker apparitions. This usually meant the replacement of visible materialisations with an invisible force through a sheet. The Scrapbook has one such instance, in the聽Psychic World,聽December 28, 1950. In this photograph and report, the medium鈥檚 hands were padlocked and the legs 鈥榤anacled鈥. Within these 鈥榝raud-proof鈥 conditions, a materialised face appeared, apparently a drawing in crumpled paper, resting on the medium鈥檚 left shoulder. These are typical for photographed materialisations which were proffered as 鈥榟ard evidence鈥 for the truth of materialisations.
A different form of materialisation was ectoplasm, the appearance of solidified mist from the medium鈥檚 orifices as a sign of their communion with the other world. Conan Doyle expressed his scepticism of ectoplasm, but other experimenters, such as Schrenck-Notzing, took the idea seriously. Eve Carri猫re, one of his subjects, used her ectoplasm to prop up paper cut-outs, a cause for criticism when viewers expected a visible being rather than invisible one pushing through paper. Very often, the ectoplasms themselves were caught, and found to be a chewed vegetable matter propped up by stiff strands or by wire. Schrenck-Notzing persisted in his general theory, despite the debunking of individual cases. In the long run, this would seriously weaken his overall credibility.
The appeal of Materialisation can thus be seen as both an evidence and a wonder. It was on one hand a proof for the truth of spiritualism, and the object of marvel for the religious element.聽 All faiths have their miracles, and Spiritualism could boast plenty, even as detractors chipped away at cases of fraud. The spectacle of manacling the medium and waiting for the materialisation to happen was a part of the theatricality of the movement, a fixed ritual which lent colour to the medium鈥檚 performances, as well as the verification of what they did.
