X Plus Y Equals Z: Or The Sleeping Preacher Of North Alabama is a book written by G. W. Mitchell and published in 1876. The book is a historical account of a preacher named James Durham who lived in North Alabama in the early 19th century. Durham was known for his unusual habit of falling into a deep sleep during his sermons, which would last for hours or even days. The book explores the various theories and explanations for this phenomenon, including spiritual possession, hypnosis, and mental illness. It also delves into the social and cultural context of the time, including the role of religion in the South and the impact of slavery on the region. The book is a fascinating look at a unique and little-known aspect of American history, and provides insight into the complexities of faith, culture, and identity in the antebellum South.Containing An Account Of Most Wonderful Mysterious Mental Phenomena, Fully Authenticated By Living Witnesses.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
