1 The book actually bore on the title-page the names of Edmund Gurney, F. W. H. Myers, and the present writer. But the division of authorship, as explained in the Preface, was as follows As regards the writing and the views expressed, Mr. Myers is solely responsible for the Introduction, and for the 'note on a Suggested Mode of Psychical Interaction;' and Mr. Gurney is solely responsible for the remainder of the book. But the collection, examination, and appraisal of evidence has been a joint labour.
