Skeptical in analysis, tireless in research, scrupulous in statement, fearless in pursuit of truth, and unmoved by the misrepresentation that pursues discoverers of vital facts, Dr. Geley's purpose in this book was to substantiate the data by the records of experimental work done by the able men who have undertaken the laborious and ungrateful task of experiment on the supernormal facts at the International Metaphysic Institute. The primary fact in subjective metaphysics is clairvoyance, and, in objective metaphysics, ectoplasm and its modifications. This work deals with each methodically and in succession as they were observed; but in the first place it is set before readers fresh to these studies the elementary principles and essential conditions of experimentation with mediums.
