Generally, the manifestations are attributed to a deceased person, known or unknown to the sitters. This is not absolute, for I have witnessed the table call itself the devil, or even pretend to be a man still alive. Automatic writing has been signed by a Mahatma; but, as a rule, it is the soul of a deceased person who claims to be manifesting. This usual attribution explains spiritistic belief. I have good reason for thinking, that the spirits of the dead have had nothing to do with my experiments; but as, in reality, I am ignorant of the cause of the phenomena which I have observed, I have politely accepted the explanation these have given of themselves. It is thus we address those whom we meet at table d’hôte, calling them by the name they give themselves without concerning ourselves as to who they really are. Therefore, whatever the changeable personification of the phenomena may be, my advice is to accept it and to heed its observations. We must not suppose the ideas expressed are due to the operators’ unconscious movements; that may be true when the communications are obtained through automatic writing, through a table or articles with which the experimenters are in contact; but it is certainly not so when they are obtained by raps given without any contact whatsoever, as I have been able to prove many and many a time. As I confine myself to indicating the results of my personal experience, it is perhaps enough to say once more that the methods I recommend seem good to me. I have always noticed the unhappy consequences of my refusal to take into account the spontaneous advice of the personification. The most frequently given advice concerns the placing of the experimenters. However, at the beginning of the sitting, the experimenters may seat themselves as they please. I have already said it was generally necessary to place the medium’s chair against the curtains of the cabinet, and to alternate the sexes. The experimenters seated, the experiment begins. It is a good plan to choose a manager. Nothing is worse than the absence of direction. When every one wishes to direct the proceedings, confusion reigns in the circle, and results are bad. I have been present at seances where every one spoke at the same time, each one demanding a different phenomenon. As a rule, on such occasions nothing was received. Some one, therefore, ought to be appointed to conduct the experiment, especially to converse with the personification if it express a desire for conversation. When the sitters wish to make a report of an experiment, it is indispensable to intrust one of the experimenters with the task of taking notes of the incidents as they occur. This experimenter ought to form one of the circle.
