Other than to a historian Spiritualist I question the value of books that are so old.

I'd be interested to learn why this book is listed here other than its relating to Spiritualism's early history, a specialist field in this Spiritualist's experience. Those who are indeed interested in the very early history of Modern Spiritualism are recommended to read Paul Gaunt's authoritative archive freely available from:

Highly recommended for students and seekers.
