We considered a little farther back (p. 173) Col. de Rochas's strange experiment with the letter-weigher. This was considered by the experimenters as absolutely conclusive. I was curious to verify it. Here are my notes on the matter. I. November 12, 1898.--This afternoon we took a drive in a landau (Eusapia and I) in company with M. and Mme. Pallotti of Cairo, and, among other things, we visited the exhibition of chrysanthemums at the Tuileries. Eusapia is enchanted. We return about 6 o'clock. My wife seats herself at the piano, and Eusapia sings some Neapolitan airs and some little fragments of Italian operas. Afterwards we all three chat confidentially with each other. She is in a very happy state of mind, tells us how sometimes on stormy days she experiences electric cracklings and sparkling in her hair, especially on an old wound that she once received on the head. She also tells us that when she has been a long time without holding a seance she is in a state of irritation, and feels the need of freeing herself of the psychic fluid which saturates her. This avowal astonishes me, for, at the end of every seance, she seems rather to be listless and melancholy and seems to hold a sitting rather unwillingly than otherwise. She adds that she frequently has fluidic prolongations of the ends of her fingers, and, putting her two hands on my knees, the inside of the hand turned upward, at the same time spreading out the fingers and placing them opposite each other face to face, at a distance of several inches, and alternately bringing the hands together and withdrawing them, she tells us to observe from time to time the radiations which prolong the fingers by forming a sort of luminous aureole at their extremities. My wife thinks she perceives some of them. I am unable to see anything at all, in spite of all my efforts, although I change the light and shade in all sorts of ways. The salon is lighted at this time by two intense Auer burners. We go into the bedroom, lighted only by candles, and I cannot see them any better. I snuff out the candles, on the supposition that this is perhaps a case of phosphorescence; but I never perceive anything. We return to the salon. Eusapia spreads a black woollen shawl over her silk skirt and shows me the luminous effluence. But all the time I can see nothing, unless it be for a moment a kind of pale ray at the end of the index finger of her right-hand.
