We must keep "pegging away," as Lincoln said; we must accumulate fact upon fact, and add experiment upon experiment, and, I should say, not wrangle too much with incredulous outsiders about the conclusiveness of any one, but trust to the mass of evidence for conviction. The highest degree of demonstrative force that we can obtain out of any single record of investigation is, of course, limited by the trustworthiness of the investigator. We have done all that we can when the critic has nothing left to allege except that the investigator is in the trick. But when he has nothing else left he will allege that. We must drive the objector into the position of being forced either to admit the phenomena as inexplicable, at least by him, or to accuse the investigators either of lying or cheating or of a blindness or forgetfulness incompatible with any intellectual condition except absolute idiocy.
The early work of the society was devoted to an experimental investigation of thought-transference, a subject which Sir William (then Professor) Barrett had brought before the British Association in 1876. After long and patient research it was considered that thought-transference, or telepathy, as it was named by Mr. F. W. H. Myers, was an established fact. In the domain of mental phenomena much valuable work has been done by the society, and this has been placed on record in a systematic and careful manner in the society's "Proceedings." Its researches, too, into what are known as "Cross Correspondences" constitute an important phase of its activities. The investigation of the mediumship of Mrs. Piper was also a notable work, to which we shall refer later.
Where the society has been less fortunate has been in its consideration of what are known as the physical phenomena of Spiritualism. Mr. E. T. Bennett, for twenty years the assistant secretary to the society, thus refers to this aspect:
It is a remarkable thing, we are inclined to say one of the most remarkable things in the history of the society, that this branch of inquiry should have been-it is hardly an exaggeration to say-absolutely barren of result. It may also be said that the result has been barren in proportion to the simplicity of the alleged phenomena. As to the moving of tables and other objects without contact, the production of audible raps, and of visible lights, opinion, even within the society itself, to say nothing of the outside intelligent world, is in the same state of chaos as it was twenty years ago. The question of the movement of tables without contact is exactly in the state in which it was left by the Dialectical Society in the year 1869. Even then, the fact of the movement of a heavy dining-room table, untouched by anyone present, and not in the presence of a professional medium, was attested by a number of well-known men. If it was "a scandal that the dispute as to the reality of these phenomena should still be going on," when Professor Sidgwick gave his first presidential address, how much more of a scandal is it that now, after the lapse of nearly another quarter of a century, "the educated world as a body should still be simply in an attitude of incredulity." In the whole series of volumes issued by the society, there is no light whatever thrown on these simple alleged phenomena of seeing and hearing. With regard to the higher physical phenomena which imply intelligence for their production, such as Direct Writing and Spirit Photography, some investigation has been made, but to a large extent, though not entirely, with negative results.*

These sweeping charges against the society are made by a friendly critic. Let us see how Spiritualists of that time viewed its activities. To start from near the beginning, we find early in 1883, a year after the formation of the society, a correspondent writing to Light asking, "What is the distinction between the Society for Psychical Research and the Central Association of Spiritualists?" and also inquiring whether there was any antagonism between the two bodies.
