American materialization medium. After being accused of fraud she held a remarkable test séance at Onset Grove, Onset Bay, Massachusetts, on September 3, 1891, before sixty people. She was enclosed in a wire cage. Phantoms not only appeared, but the medium herself was mysteriously brought out of the cage without disturbing the seals.
Many of the phantoms were seen to build up before the cage and also to transform into other shapes. The full account of the séance, signed by twelve people present, was published in the Banner of Light (September 1891). Paul Joire wrote a brief description of this test séance in Psychical and Supernormal Phenomena (1916).
