“Last summer I went, as you know, to pass the hot weather term in the town of Meridian. The relative at whose house I had intended to stay was ill, so I sought other quarters. After some difficulty I succeeded in renting a vacant dwelling that had been occupied by an eccentric doctor with the name of Mannering, who had gone away years before, no one knew where, not even his agent. He had built the house himself and had lived in it with an old servant for about ten years. His practice, never very extensive, had after a few years been given up entirely. Not only so, but he had withdrawn himself almost altogether from social life and become a recluse. I was told by the village doctor, about the only person with whom he held any relations, that during his retirement he had devoted himself to a single line of study, the result of which he had expounded in a book that did not commend itself to the approval of his professional brethren, who, indeed, considered him not entirely sane. I have not seen the book and cannot now recall the title of it, but I am told that it expounded a rather startling theory. He held that it was possible in the case of many a person in good health to forecast his death with precision, severalmonths in advance of the event. The limit, I think, was eighteen months. There were local tales of his having exerted his powers of prognosis, or perhaps you would say diagnosis；and it was said that in every instance the person whose friends he had warned had died suddenly at the appointed time, and from no assignable cause. All this, however, has nothing to do with what I have to tell；I thought it might amuse a physician.”
