PUBLISHERS' PREFACE.

WE take pleasure in offering this volume as a compend of the harmonial philosophy of Spiritualism, and as a repository of Facts demonstrating the grand truth of open communication between the two worlds. Of all the author's works, this is, without doubt, the most complete in treating of the laws and conditions of mediumship; being most thoroughly devoted to a consideration and elucidation of the facts and principles of Spiritualism, both ancient and modern. We therefore present this book as embodying important and reliable information on the most interesting subject known to the mind of man-"Life and Immortality."

AUTHOR'S INTRODUCTION.

THE author has obeyed his impressions in presenting to the world this book. Its contents, revised and enlarged, are designed to meet the psychological demands of the time. The heart and the head, the soul and the understanding, are particularly and familiarly addressed.

To the down-trodden and wearied, to the trammeled and enslaved, to the depressed and sorrowful, to the seeker after light and liberty, this book is most cordially dedicated by the author. He can think of no better offering-no legacy more adapted to the development and tranquilization of man's nature-than the one now laid upon the altar of the reader's Reason.

"Let there be Light!" was the first and most omnipotent mandate of Heaven; it reverberated throughout the length and breadth of the arching skies; it has rolled down from generation to generation with everincreasing power; and now it seeks an expression from every heart that beats in unison with the sovereign laws of universal justice and equal liberty.

That there may "be Light" on the important questions now agitating the people, and that "mental liberty" may come with it, is the deepest and foremost prayer of the author; and he earnestly hopes, and even ventures to believe, that the following pages will serve to conduct the reader to the attainment and enjoyment of these inestimable blessings.

NEW YORK, Nov. 18, 1868.
