Levitation seems to me more difficult to realise than gliding movements. I have frequently obtained the latter without contact, by directing the palm of my hand towards the table, and trying to draw it after me as though an elastic thread united the table to my hand. Under these conditions the table seems to obey a kind of attraction. I think I have some observations to make on this subject, but I cannot formulate them with much certitude, and I only point them out in order to provoke—if that be possible—the examination of these facts by persons more competent than I am. First of all, it is not always the medium who obtains the best results in the manœuvre I indicate. I have seen some experimenters obtain more marked movements than the sensitive himself. This is not generally the case, but the fact does not appear to me to be rare. It is rather disconcerting, because those persons, who in a seance manifest a force relatively greater than the medium’s, cannot obtain any supernormal fact when alone; the presence of a medium is necessary for the energy of their action to be manifested. I wonder if this be not due to the medium’s inexperience. I never observed this peculiarity in seances with Eusapia, although the sitters could, in her presence, produce certain phenomena themselves. I have only noticed it with the non-professional mediums, who kindly consented to allow me to experiment with them. Nearly all of them had no notion whatever of psychical experimentation; most of them were altogether ignorant of the practices of spiritism; and many were frightened by their first phenomena. These mediums have not the tranquillity and presence of mind of myself and friends, whom a long experience has freed from all kinds of bias. Perhaps, therefore, they do not operate under such good conditions as we do, or as more experienced mediums would. Whatever may be the reason, I note the fact observed. A second interesting observation I have to make is the unequalness of the radiations or emanations which appear to issue from the back or palm of the hand. The action of the palm is decidedly more energetic than that of the back; as an example, I will recall to mind the experiment with the letter-balance. To lower it, Eusapia lightly moved her hand from top to bottom, palm downwards; to obtain the contrary movement, she turned her hand in the opposite direction. There are certain obscure peculiarities to elucidate in this curious unequalness. It is desirable to study it, for it is one of the rare points where experimentation is really possible, in the studies of the kind I am setting forth. It is to be noted, and this is I think a very important consideration, that the innervation of the palm of the hand is much more abundant than that of the back. In what concerns movements without contact, I have not noticed any unequalness of action between the two hands: the left hand appears to act quite as well as the right.
