It will not be out of place, here, to mention the circumstance recorded in Professor Gregory’s “Abstract of Baron von Reichenbach’s Researches in Magnetism,” regarding a person called Billing, who acted in the capacity of amanuensis to the blind poet Pfeffel, at Colmar. Having treated of various experiments, by which it was ascertained that certain sensitive persons were not only able to detect electric influences of which others were unconscious, but could also perceive, emanating from the wires and magnets, flames which were invisible to people in general; “the baron,” according to Dr. Gregory, “proceeded to a useful application of the results, which is, he says, so much the more welcome, as it utterly eradicates one of the chief foundations of superstition, that worst enemy to the development of human enlightenment and liberty. A singular occurrence, which took place at Colmar, in the garden of the poet Pfeffel, has been made generally known by various writings. The following are the essential facts. The poet, being blind, had employed a young clergyman, of the evangelical church, as amanuensis. Pfeffel, when he walked out, was supported and led by this young man, whose name was Billing. As they walked in the garden, at some distance from the town, Pfeffel observed, that as often as they passed over a particular spot, the arm of Billing trembled, and he betrayed uneasiness. On being questioned, the young man reluctantly confessed, that as often as he passed over that spot, certain feelings attacked him, which he could not control, and which he knew well, as he always experienced the same, in passing over any place where human bodies lay buried. He added, that at night, when he came near such places, he saw supernatural appearances. Pfeffel, with the view of curing the youth of what he looked on as fancy, went that night with him to the garden. As they approached the spot in the dark, Billing perceived a feeble light, and when still nearer, he saw a luminous ghostlike figure floating over the spot. This he described as a female form, with one arm laid across the body, the other hanging down, floating in the upright posture, but tranquil, the feet only a hand-breadth or two above the soil. Pfeffel went alone, as the young man declined to follow him, up to the place where the figure was said to be, and struck about in all directions with his stick, besides running actually through the shadow; but the figure was not more affected than a flame would have been; the luminous form, according to Billing always returned to its original position after these experiments. Many things were tried during several months, and numerous companies of people were brought to the spot, but the matter remained the same, and the ghost-seer adhered to his serious assertion, and to the opinion founded on it, that some individual lay buried there. At last, Pfeffel had the place dug up. At a considerable depth was found a
