''A Book Written By The Spirits Of The So-Called Dead, With Their Own Materialized Hands, By The Process Of Independent Slate Writing'' is a non-fiction book written by Carl Gustaf Helleberg in 1883. The book is a collection of messages and writings supposedly written by spirits of the deceased through the process of independent slate writing. The author claims that the spirits were able to materialize their own hands and write messages on a slate board without any human intervention. The book provides a detailed account of the process and includes examples of the messages written by the spirits. The author also includes his own commentary on the messages and their significance. The book was controversial at the time of its publication and remains a curious artifact of the spiritualist movement.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
