A liberal hour being over, and my dolphin-like recreation ended, my new friend entered into desultory chat, and asked me, among other things, if I had not written something on the divining-rod. I replied to his question by giving him the copy I had of “the Letters;” and promised, as a New-Year’s gift for the morrow, to present him with the implement itself. And I lent him Von Reichenbach’s book on Od, with which he was unacquainted. Then he told me that there were two or three experiments, possibly akin to trials with the divining-rod, with which he had been familiar for years, and which he had shown to many without receiving an explanation of them. He said that as far as he knew they were original and his own; and that he would willingly show them to me. He wanted only for that purpose a piece of silver, a gold ring, and a bit of silk. These were easily found. And he attached the silk to the ring, which he then held suspended by the silk over a silver spoon, at a distance of half an inch. Shortly the ring shaped its first vague movements into regular oscillations in a direction to and fro, or towards and from, Herr Caspari. I will call such oscillations _longitudinal_. It was evident to me, that this phenomenon must be akin to the motion of the divining-rod. Then, at Herr Caspari’s suggestion, I summoned the maid, who was directed to place her hand in Herr Caspari’s disengaged hand. On her doing so, the oscillations of the ring became _transverse_. How pregnant was this fact! An Od-current had been established between the two experimenters; and the apparent influence of the two metals on each other had been modified. Herr Caspari told me that, as far as he knew, these experiments would only succeed when made with silver and gold, and a bit of silk. But he said that he had still another experiment to show me, which he did the following day. He said he had a little pea-like bit of something, which he had been told was _schwefel-kies_, that exhibited another motion: when held suspended by silk over either of the fingers, it rotated one way; when held suspended over the thumb, it rotated in the contrary direction. Herr Caspari left me, after agreeing to assist me in the further examination of these phenomena; and the New Year coming in found me in busy thought how to elicit, through variations of Herr Caspari’s experiments, some important physical evidence as to the reality and agency of Von Reichenbach’s Od-force.
