"The result justified my expectation in the fullest measure. She saw, very soon, a light, and perceived, on one of the grave mounds, along its whole extent, a delicate, fiery, as it were a breathing flame. The same thing was seen on another grave, in a less degree. But she met neither witches nor ghosts. She described the flame as playing over the graves in the form of a luminous vapor, from one to two spans in height. "Some time afterwards I took her to two great cemeteries, near Vienna, where several interments occur daily, and the grave mounds lie all about in thousands. Here she saw numerous graves, which exhibited the lights above described. Wherever she looked, she saw masses of fire lying about; but it was chiefly seen over all new graves, while there was no appearance of it over very old ones. She described it less as a clear flame than as a dense, vaporous mass of fire, holding a middle place between mist and flame. On many graves this light was about four feet high, so that when she stood on the grave it reached to her neck. When she thrust her hand into it, it was as if putting it into a dense, fiery cloud. She betrayed not the slightest uneasiness, as she was, from her childhood, accustomed to such emanations, and had seen, in my experiments, similar lights produced by natural means, and made to assume endless varieties of form. I am convinced that all who are, to a certain degree, sensitive, will see the same phenomena in cemeteries, and very abundantly in the crowded cemeteries of large cities; and that my observations may be easily repeated and confirmed." These experiments were tried in 1844. A postscript was added in 1847. Reichenbach had taken five other sensitive persons, in the dark, to cemeteries. Of these, two were sickly, three quite healthy. All of them confirmed the statements of Mademoiselle Reichel, and saw the lights over all new graves, more or less distinctly; "so that," says the philosopher, "the fact can no longer admit of the slightest doubt, and may be every where controlled. "Thousands of ghost stories," he continues, "will now receive a natural explanation, and will thus cease to be marvellous. We shall even see that it was not so erroneous or absurd as has been supposed, when our old women asserted, as every one knows they did, that not every one was privileged to see the spirits of the departed wandering over their graves. In fact, it was at all times only the sensitive who could see the imponderable emanations from the chemical change going on in corpses, luminous in the dark. And thus I have, I trust, succeeded in tearing down one of the densest veils of darkened ignorance and human error."
