Psychics

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. Since the appearance Of these articles a hundred questions have been asked. I propose to take occasion of this preface to answer some of them a little more fully than is practicable by letter, and also to save myself the labor of writing the same things to so many different persons. No end of people write and ask if these phenom ena may not be explained by this theory or that. It may not be out of the way to say that one who has been studying the matter for eighteen years, has probably considered, with some care, all the theories he could think of. He will be grateful, however, for anything, by way of suggestion, that is not already long familiar.
