Many friends and correspondents have suggested that I should republish
a number of articles which have appeared from time to time in various
quarters. The present volume brings these articles together, with some
which have not appeared before.
Each chapter is complete in itself, but there is more or less connexion,
for each deals with some aspect of the subject to which I have given
most attention during the last twelve years--namely, psychical research.
I thank the editors of the _Holborn Review_, _National Review_, _World's
Work_, and _Occult Review_ for permission to republish articles which
have appeared in their pages.
