Spirit Mediumship 
Its Various Phases, How Developed and Safely Practiced, a Compendium of Psychic Science, for Seances, Circles and Individual Use, the Medium’s Companion and Guide

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Experience is the greatest teacher, and the author of this book being a medium himself with many years of active service, and having personally experienced nearly every phase of mediumship mentioned in this work, naturally feels that he is better qualified to speak upon the subject than are many authors of note who have developed no mediumship themselves, and whose knowledge of the subject has come to them sec ond hand, as all they know has been acquired by oh servation of the phenomena occurring through others. The facts here recorded are based entirely upon the author’s forty-six years and more of daily experience through his own mediumship, and the teachings of his spirit inspirers, as well as through the mediumship of his wife and many others. His knowledge of the sub jcet being founded on personal experience, may furnish an excuse and partially justify the frequent personal reference made throughout the book.
