Among the objects in mind were: (1) To study the materials in their strict chronological order, day by day. The mode of presentation in _Mental Radio_ was to give some of the most striking results first, then many more that were more or less classified according to subjects and aspects. This is effective for popular reading but not satisfactory to the serious student. (2) To see if there were signs, in any part of the results, of profiting from normal knowledge, whether consciously or subconsciously acquired, of what the “agent” had drawn. Mr. Sinclair took this theory into account and quite decidedly killed it, but it was my duty to try it out anew by my own processes, with the same rigor shown in relation to my own wife and my daughter in _The Psychic in the House_. Later, in summary fashion, these tests will be set forth. (3) To try out other theories to account for the ratios and degrees of correspondence between “original drawings” and “reproductions” in the Sinclair experiments, such as involuntary whispering and chance coincidence. (4) To make a large number of guessing tests on the basis of the Sinclair originals, both as a means of deciding whether the “mere coincidence” theory is tenable (as aforesaid) and, if it should prove otherwise, in order to make a rough measurement of the disparity between telepathic results and those of guessing. (5) In the event that there appeared to be no reasonable escape from conclusion that telepathy is displayed by the material, to ascertain (a) whether the telepathic faculty with Mrs. Sinclair was constant, vacillating, progressively constant, or what; (b) whether the telepathic impressions came to her in the form of ideas, images, names or in more than one fashion; (c) whether any further hints as to the mental processes involved could be discerned or any particular pieces of information isolated which might be helpful in this field of study. (6) Finally, to urge readers to institute experiments of their own, and to give amateurs some directions as to procedure. If many could be persuaded to start “games” of this character with their friends, doubtless favorable subjects could be discovered or developed. Attention being called to these persons, series of tests could be made with them under conditions against which none of the old objections could be offered.[3] The Sinclair experiments are treated first in this Bulletin, since they are its chief subject. The drier Historical Notes, presenting a sketch of the first steps in methodical research relating to alleged Thought-Transference, with summaries of some of the classic series of tests, particularly such as are based upon drawings, are relegated to Part Two. The more earnest and methodical students of such matters will prefer to read that first.
