One man's authority here is by no means final. F.W.H. Myers has taken into consideration many of the facts upon which Boirac dwells and on the whole has reached a different conclusion. But, in general, the more deeply we advance into the region of abnormal personality and the phenomena of hypnotic and related states, the more reason there seems to be for believing that there are resident in human personality powers which, if at once evoked and released, are sufficient to account for all mediumistic revelations without assuming that they come from the discarnate. _Geley's Conclusions_ Geley has gone much farther in some directions here than any one else. He is more concerned with the physical phenomena. He has a striking series of photographs of materialization, the authenticity of which it is difficult to doubt. He finds an ascending series in abnormal psychology from neuropathic states to mediumship with gradations which intensify the abnormal or the supernormal, but in which the continuity of development is never broken. His analyses here are both keen and suggestive and tend to confirm the conclusions of other students that we have resident in human personality elements which are adequate to the explanation of any phenomena which have been as yet presented. As far as the physical phenomena go, he cites experiments which seem to reveal "threads of substance and rigid rods, sometimes visible, sometimes invisible, proceeding from the fingers of the medium" and serving as a real mechanism for the movement of distant and sometimes quite heavy articles. He argues from this that there is a possible exteriorization of power which may itself be governed by ideas and believes also that such facts as this will eventually compel us to recast our conceptions of matter and force and profoundly affect biology and all evolutionary theories. The whole matter is necessarily obscure, but such studies do give a new direction and a larger significance to our whole subject matter.
