Publisher's Synopsis
This pro-spiritualist booklet was written in the mid 1800s by Allen Putnam, who here claimed to have tested various aspects of mesmerism and mediumship and concluded that the spirit world is quite real. It touches upon the tappings and moanings of spirits, and even links the Salem Witch Trials to mediumship. Putnam additionally crafted a simplistic classification system for several increasingly potent aspects of mesmerism (later conflated with hypnotism) and the powers derived from interactions with spirits.
