"On one of these occasions a man was sent for who made a regular profession of finding water by the divining rod; there happened to be a large party staying at the house, and the whole company turned out to see the fun. The rod gave indications in the usual way, and water was ultimately found at the spot. Mrs. C----, utterly sceptical, took the rod into her own hands to make experiment, believing that she would prove the man an impostor; and she said afterwards she was never more frightened in her life than when it began to move, on her walking over the spring. Several other gentlemen and ladies tried it, but it was quite inactive in their hands. 'Well,' said the host to his wife, 'we shall have no occasion to send for the man again, as you are such an adept.' "Some months after this, water was wanted in another part of the estate, and it occurred to Mrs. C---- that she would use the rod again. After some trials, it again gave decided indications, and a well was begun and carried down a very considerable depth. At last she began to shrink from incurring more expense, but the laborers had implicit faith; and begged to be allowed to persevere. Very soon the water burst up with such force that the men escaped with difficulty; and this proved afterwards the most unfailing spring for miles round. "You will take the above for what it is worth; the facts I have given are undoubtedly true, whatever conclusions may be drawn from them. I do not propose that you should print my narrative, but I think in these cases personal testimony, even indirect, is more useful in forming one's opinion than a hundred old volumes. I did not hear it from Mrs. C----'s own lips, but I was sufficiently acquainted with her to form a very tolerable estimate of her character; and my wife, who has known her intimately from her own childhood, was in her younger days often staying with her for months together." I remember having been much perplexed by reading a series of experiments made with a pendulous ring over metals, by a Mr. Mayo: he ascertained that it oscillated in various directions under peculiar circumstances, when suspended by a thread over the ball of the thumb. I instituted a series of experiments, and was surprised to find the ring vibrate in an unaccountable manner in opposite directions over different metals. On consideration, I closed my eyes whilst the ring was oscillating over gold, and on opening them I found that it had become stationary. I got a friend to change the metals whilst I was blindfolded--the ring no longer vibrated. I was thus enabled to judge of the involuntary action of muscles, quite sufficient to have deceived an eminent medical man like Mr. Mayo, and to have perplexed me till I succeeded in solving the mystery.[24] FOOTNOTES: [23] Hos. iv. 12. [24] A similar series of experiments was undertaken, as I learned afterwards, by M. Chevreuil in Paris, with similar results. The Seven Sleepers of Ephesus.
