'On the 30th of the same month, at about four o'clock, P. M., Mrs B. came down stairs into the drawing room, which she had quitted a few minutes before, and on entering the room, saw me, as she supposed, standing with my back to the fire. She addressed me, asking how it was I had returned so soon. (I had left the house for a walk half an hour before.) She said I looked fixedly at her with a serious and thoughtful expression of countenance, but did not speak. She supposed I was busied in thought, and sat down in an arm-chair near the fire, and within a couple of feet at most of the figure she still saw standing before her. As, however, the eyes still continued to be fixed upon her, after a few moments she said--'Why don't you speak--?' The figure upon this moved off towards the window at the farther end of the room, the eyes still gazing on her, and passed so very close to her in doing so, that she was struck by the circumstance of hearing no step nor sound, nor feeling her clothes brushed against, nor even any agitation of the air. The idea then arose for the first time into her mind, that it was no reality, but a spectral illusion, (being a person of sense and habituated to account rationally for most things, the notion of anything supernatural was out of the question.) She recollected, however, your having mentioned that there was a sort of experimentum crucis, applicable to these cases, by which a genuine ghost may be distinguished from one conjured up by merely natural causes; namely, the pressing the eye in order to produce the effect of seeing double, when, according to your assertion, a true Tartarean ghost may be duplicated as well as everything else; while the morbid idea being, I suppose, an impression on the retina, would or ought to remain single. I am sorry, however, to say, that the opportunity for verifying your theory was unfavorable. Before Mrs B. was able distinctly to double her vision, my figure had retreated to the window and disappeared there. The lady followed, shook the curtains, and tried the windows, being still loth to believe it was not a reality, so distinct and forcible was the impression. Finding, however, that there was no natural means of egress, she became convinced of having seen a spectral apparition, such as are recorded in Dr Hibbert's work, and consequently felt no alarm or agitation. The appearance lasted four or five minutes. It was bright daylight, and Mrs B. is confident that the apparition was fully as vivid as the reality; and when standing close to her, it concealed, of course, the real objects behind it. Upon being told of this my visible appearance in the spirit, having been only _audible_ a few days before, I was, as you may imagine, more alarmed for the health of the lady than for my own approaching death, or any other fatality the vision might be supposed to forebode. Still both the stories were so very much _en regle_ as ghost stories, the three calls of the plaintive voice, each one louder
