hack cab the things I had left there, with my poor dog's body. In this task I was not disturbed, nor did any incident worth note befall me, except that still, on ascending and descending the stairs, I heard the same footfall in advance. On leaving the house, I went to Mr. J----'s. He was at home. I returned him the keys, told him that my curiosity was sufficiently gratified, and was about to relate quickly what had passed, when he stopped me, and said, though with much politeness, that he had no longer any interest in a mystery which none had ever solved.I determined at least to tell him of the two letters I had read, as well as of the extraordinary manner in which they had disappeared, and I then inquired if he thought they had been addressed to the woman who had died in the house, and if there were anything in her early history which could possibly confirm the dark suspicions to which the letters gave rise. Mr. J---- seemed startled, and, after musing a few moments, answered: "I am but little acquainted with the woman's earlier history, except, as I before told you, that her family were known to mine. But you revive some vague reminiscences to her prejudice. I will make inquiries, and inform you of their result. Still, even if we could admit the popular superstition that a person who had been either the perpetrator or the victim of dark crimes in life could revisit, as a restless spirit, the scene in which those crimes had been committed, I should observe that the house was infested by strange sights and sounds before the old woman died--you smile--what would you say?""I would say this, that I am convinced, if we could get to the bottom of these mysteries, we should find a living human agency.""What! you believe it is all an imposture? for what object?""Not an imposture in the ordinary sense of the word. If suddenly I were to sink into a deep sleep, from which you could not awake me, but in that sleep could answer questions with an accuracy which I could not pretend to when awake--tell you what money you had in your pocket--nay, describe your very thoughts--it is not necessarily an imposture, any more than it is necessarily supernatural. I should be, unconsciously to myself, under a mesmeric influence, conveyed to me from a distance by a human being who had acquired power over me by previous _rapport_.""But if a mesmerizer could so affect another living being, can you suppose that a mesmerizer could also affect inanimate objects; move chairs--open and shut doors?""Or impress our senses with the belief in such effects--we never having been _en rapport_ with the person acting on us? No. What is commonly called mesmerism could not do this; but there may be a power akin to mesmerism and superior to it--the power that in the old days was
