Spiritistic mediums, whose number is legion, form another category with whom we should not experiment, except for purposes of especial research. Some of these mediums are trustworthy, and one of them, Madame Agullana of Bordeaux, has sometimes given me interesting sittings. The phenomena I have observed with this medium differ greatly from Eusapia’s; they are of an intellectual order, and raise a very complicated problem. Madame Agullana’s medianity must not be judged from seances with her groups. These seances have the religious character of nearly all truly spiritistic meetings. It is difficult there for an experimenter to observe at his ease; the curiosity of those who seek only the objective demonstration of a fact may appear impertinent and out of place at such meetings. The faithful have a right to look upon such people as intruders. Convinced of the truth of their doctrines, they ill brook the open discussion of them at meetings, where discussion is not wanted. They prefer the discourses of an entranced medium to the needless interference of the profane. Their meetings, nearly always consecrated to the acquiring of communications, have the serious defect of developing unconscious automatism in their medium. For me this is a conclusive reason. Madame Agullana, at some seances where only a few experimentalists took part, gave proof of the possession of certain supernormal faculties, which I have not observed in the same degree of intensity at the usual sittings of her group. This medium is also entirely reliable, and of praiseworthy disinterestedness. She never receives any remuneration—an important consideration—for, mediums who take fees are more open to suspicion. My most convincing results have been obtained with persons unacquainted with spiritism and ignorant of its practices. Once I discovered a medium most unexpectedly. He sat down with me at a table, invited to experiment for the first time in his life. He had scarcely seated himself when violent knockings resounded on the floor; this person, honourable, well-educated and intelligent, is one of the most remarkable sensitives I have met with. But as he fears ridicule, has no desire to be scoffed at in newspapers, and, moreover, dreads publicity of any kind, he does not wish his name to be mentioned. These are the results of the malevolent criticisms heaped upon experiments of this nature. I am sure the number of mediums is much more considerable than we think; in a circle of from eight to ten people chosen under the condition I have mentioned, it is seldom we do not find a medium. Of whatever sex, to whatever social status he may belong, the medium is a sensitive. This must never be forgotten; and we must never lose sight of the fact, that the phenomena will be clearer and better in proportion as the medium’s confidence and sympathy are won.
