Abstract

Tyrrell\'s 2 "classics" are here republished in 1 volume, with completely separate treatment for each work (tables of contents, prefaces, indexes, etc.). The longer of the 2 works was first published in 1938, and it is a survey for the scientific reader of the field of parapsychology as of that stage in its development. The shorter work was first given limited publication by the Society for Psychical Research in 1943, but the version reprinted here is the edition published posthumously in 1953, edited by Edward Osburn and with a preface by H. H. Price. In it Tyrrell develops a telepathic theory of the spontaneous parapsychical experiences with which he was especially concerned--those which take the form of hallucinations.
