Fox Sisters - Confession

Confession

Margaret told her story of the origins of the mysterious "rappings" in a signed confession given to the press and published in New York World, October 21, 1888. In it, she explained the Hydesville Events.

She also expanded on her career as a medium after leaving the homestead to begin her Spiritualist travels with her older sister, Mrs. Underhill:

"Mrs. Underhill, my eldest sister, took Katie and me to Rochester. There it was that we discovered a new way to make the raps. My sister Katie was the first to observe that by swishing her fingers she could produce certain noises with her knuckles and joints, and that the same effect could be made with the toes. Finding that we could make raps with our feet – first with one foot and then with both – we practiced until we could do this easily when the room was dark. Like most perplexing things when made clear, it is astonishing how easily it is done. The rapping are simply the result of a perfect control of the muscles of the leg below the knee, which govern the tendons of the foot and allow action of the toe and ankle bones that is not commonly known. Such perfect control is only possible when the child is taken at an early age and carefully and continually taught to practice the muscles, which grow stiffer in later years. ... This, then, is the simple explanation of the whole method of the knocks and raps."

She also notes:

"A great many people when they hear the rapping imagine at once that the spirits are touching them. It is a very common delusion. Some very wealthy people came to see me some years ago when I lived in Forty-second Street and I did some rappings for them. I made the spirit rap on the chair and one of the ladies cried out: "I feel the spirit tapping me on the shoulder." Of course that was pure imagination."

The cracking of joints was the theory skeptics most favored to explain the rappings, a theory dating back to 1851. Spiritualists familiar with the wide range of raps produced by the sisters, as well as the fact that raps could emanate from any part of a room, were not much impressed by the fact that raps could emanate from Margaret's toe. Much more damaging was the realization that Margaret could produce raps at will, when the raps were supposedly produced by spirits. But Spiritualists such as Arthur Conan Doyle were soon able to accept that, up to a point, the medium's own will could influence the preternatural phenomena of the séance.

Harry Houdini, a man who devoted a large part of his life to debunking Spiritualist claims, provides this insight:

"As to the delusion of sound. Sound waves are deflected just as light waves are reflected by the intervention of a proper medium and under certain conditions it is a difficult thing to locate their source. Stuart Cumberland told me that an interesting test to prove the inability of a blindfolded person to trace sound to its source. It is exceedingly simple; merely clicking two coins over the head of the blindfolded person."
