Ghosts in Solid Form

Ghosts in Solid Form is a book by Gambier Bolton, first published in 1919. In this compact, early-20th-century investigation Bolton collects eyewitness accounts and experimental records from sittings and séances that probe the controversial phenomenon known to spiritualists and psychical researchers as materialisation — the apparent physical manifestation of spirits.

Written from the standpoint of an inquisitive observer rather than a sensationalist, the book examines mediumship, photographic evidence, and laboratory-style experiments that attempt to test whether ghosts can take on tangible form. Read today as a curious historical document of psychical research, the work sits at the intersection of spiritualism, paranormal investigation, and the emerging scientific methods of its time.

It will appeal to readers interested in ghost stories grounded in purported evidence, historians of occultism, and anyone studying the development of psychical research and mediumship practices in the late Victorian and Edwardian eras.
