Hours with the Ghosts [EPUB ebook] 

First published in 1897, ‚Hours with the Ghosts‘ (or,
‚Nineteenth Century Witchcraft‘) by Henry Ridgely Evans is a collection of investigations into the Phenomena of Spiritualism and Theosophy split into 2 parts, the first of which discusses spiritualism and related phenomena; the second part discusses Theosophy and Theosophists, including Helena Blavatsky.
Excerpt from the Preface:
‚In this work the author has endeavored to give an accurate account of the lives and adventures of celebrated mediums and occultists, which will prove of interest to the reader. The rise and growth of the Theosophical cult in this country and Europe is of historical interest. Theosophy pretends to a deeper metaphysics than Spiritualism, and numbers its adherents by the thousands; it is, therefore, intensely interesting to study it in its origin, its founder and its present leaders.‘
