Allow me to add that I can find no evidence even tending to prove that this force is other than a force proceeding from, or directly dependent upon, the human organization, and therefore, like all other forces of nature, wholly within the province of that strictly scientific investigation to which you have been the first to subject it. Now that it is proved by mechanical tests to be a fact in nature (and if a fact, it is impossible to exaggerate its importance to physiology and the light it must throw upon the obscure laws of life, of mind and the science of medicine) it cannot fail to command the immediate and most earnest examination and discussion by physiologists and by all who take an interest in that knowledge of "man," which has been truly termed "the noblest study of mankind." To avoid the appearance of any foregone conclusion, I would recommend the adoption for it of some appropriate name, and I venture to suggest that the force be termed the Psychic Force; the persons in whom it is manifested in extraordinary power Psychics; and the science relating to it Psychism as, being a branch of psychology. The preceding article was published separately by William Crookes in a special brochure which lies before me,[66] and which contains, in addition, the following study, not less curious from the human and anecdotical point of view than from the point of view of the experimenter in physics: When I first stated in this journal that I was about to investigate the phenomena of so-called Spiritualism, the announcement called forth universal expressions of approval. One said that my "statements deserved respectful consideration"; another expressed "profound satisfaction that the subject was about to be investigated by a man so thoroughly qualified as," etc.; a third was "gratified to learn that the matter is now receiving the attention of cool and clear-headed men of recognized position in science"; a fourth asserted that "no one could doubt Mr. Crookes's ability to conduct the investigation with rigid philosophical impartiality"; and a fifth was good enough to tell its readers that "if men like Mr. Crookes grapple with the subject, taking nothing for granted until it is proved, we shall soon know how much to believe."
