It is not at all difficult to account for the fact that Professor McDougall’s results were not quite up to the average of Mrs. Sinclair’s work during the period covered by _Mental Radio_, both quantity and quality taken into consideration. In the first place, it has for many years been evident that something depends upon the degree of _rapport_ between agent and percipient; in other words, that some persons are better suited than others to act as agents in relation to a particular percipient. Thus, we are told in the book (pages 33–34) that among the friends of Mrs. Sinclair there was one peculiarly adapted in this respect—Mrs. Kate Crane-Gartz. I venture to relate my own very limited experience, as fact, not scientifically guaranteed. I have had reason to suppose that I was getting telepathic messages only with two persons. One was with my wife the first time I ever experimented with her, and then I got most of the objects she was thinking of, more or less satisfactorily, in about eight trials. But I never again had _any_ measurable success with her, though I tried repeatedly. The other person I was for a time in sympathetic relations with, and there occurred a number of incidents which convinced me that I was acting as a spontaneous percipient. The most striking category of these is the same which Mr. Sinclair describes when he says: “My wife will say to me, ‘Mrs. Gartz is going to phone,’ and in a minute or two the phone will ring.” Repeatedly, when I had no particular reason to think that the lady to whom I refer would ‘phone me, and when I was occupied with work, I would suddenly, as by a jerk, look at the ‘phone, expecting it to ring, and in a few moments it would do so. I have even gone to the ‘phone, almost without thinking, and stood there for half a minute or so before it did so. This period lasted for perhaps three or four months only, then faded out. Never at any other time, nor with any other person, not even with my daughter between whom and me there is the most cordial sympathy, has there been evidence of this kind sufficiently striking and repetitious to arrest serious attention. So it may well be that Professor McDougall, however amiable and fairminded he is, not having been long known to the percipient and being invested with the awe of a psychologist of extended reputation, was not so well adapted to be an agent in relation to her as her husband or her brother-in-law.
