Senses used by mental mediums are sometimes defined differently from in other paranormal fields. A medium is said to have psychic abilities but not all psychics function as mediums. The term clairvoyance, for instance, may include seeing spirit and visions instilled by the spirit world. The Parapsychological Association defines "clairvoyance" as information derived directly from an external physical source.
In September 1878 the British medium Charles Williams and his fellow-medium at the time, A. Rita, were detected in trickery at Amsterdam. During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums. In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin.
During our interview, ESP’s manager “Sandy” told me I would make $7 an hour. (The contract indicated I could make as much as $12 an hour.) But it turned out the “per hour” meant not how much time I was logged on but how much time I had callers on the line. Various places in the contract and the guidance site indicated that during a “pay period” of uncertain length, I had to have talked for 30, 120, or 600 minutes in order to qualify for a paycheck. I realized I could make more money if I set up a card table in front of my house and asked for donations for readings.

ISBN 978-0-8058-0508-6 "The spirits, controls, and guides of a medium are the products of the medium's own psychological dynamics. On the one hand, they personify the medium's hidden impulses and wish life. On the other, they are also shaped by the expectations of the medium's sitters, the medium's experience, the cultural background, and the spirit of the times."
Some scientists of the period who investigated spiritualism also became converts. They included chemist Robert Hare, physicist William Crookes (1832–1919) and evolutionary biologist Alfred Russel Wallace (1823–1913). Nobel laureate Pierre Curie took a very serious scientific interest in the work of medium Eusapia Palladino. Other prominent adherents included journalist and pacifist William T. Stead (1849–1912) and physician and author Arthur Conan Doyle (1859–1930).
