We had at the Psychology Society a few séances with the medium Eusapia Paladino. It was very interesting, and truly those phenomena that we have witnessed seemed to us to not be some magical tricks — a table lifted four feet above the floor, movements of objects, feelings of hands that pinched you or caressed you, apparitions of light. All this in a room arranged by us, with a small number of spectators all well known and without the presence of a possible accomplice. Cheating would only be possible if the medium had extraordinary abilities as a magician. But how to explain the different phenomena when we are holding her hands and legs, and the lighting of the room is sufficient to see everything going on?
