«In the course of his investigations into spiritualism he [Leadbeater] had been attending a series of séances with William Eglinton (1857—1933). Eglinton was a leading exponent of slate writing, a technique popular for a time, in which a sealed slate would have a message written on it during a séance, even though the slate was supposedly inaccessible to human agents. Eglinton had previously provided more spectacular phenomena in the form of levitation and materializations, once being — so it was claimed — „translated“ from one room to another during a séance».[20]
