Concerning the power possessed in the nerve centres of this woman, to produce sounds at a distance, Dr. Kerner remarks as follows: "As I had been told by her parents, before her father's death, that, at the period of her early magnetic state, she was able to make herself heard by her friends, as they lay in bed at night, in the same village, in other houses, by a knocking,—as is said of the dead,—I asked her, in her sleep, whether she was able to do so now, and at what distance. She answered that she could sometimes do it. Soon after this, as we were going to bed, (my children and servants being already asleep,) we heard a knocking, as if in the air over our heads; There were six knocks, at intervals of half a minute. It was a hollow, yet clear sound, soft, but distinct. We were certain there was no one near us, nor over us, from whom it could proceed; and our house stands by itself. On the following evening, when she was asleep, (we had mentioned the knocking to nobody whatever,) she asked me whether she should soon knock to us again; which, as she said it was hurtful to her, I declined." And yet, not long after this, Kerner relates the following, as having taken place at his house: "On the morning of the 23d of March, 1837, at one o'clock, I suddenly awoke, and heard seven knocks, one after another, at short intervals, seeming to proceed from the middle of my chamber: my wife was awakened also; and we could not compare this knocking to any ordinary sound. Mrs. Hauffe lived several houses distant from us."
"On the 30th of the same month, Rev. Mr. Hermann came into rapport or special relation with Mrs. H., through the medium of psychological sympathy, as well as through the physical influence. Previous to this he had not been troubled with strange sounds at his house, but after that period he was awakened every night, at a particular hour, by a knocking in his room,—sometimes on the floor, and sometimes on the walls,—which his wife heard as well as himself. In a great part of her magnetic state, Mrs. H. was under a strong state of religious feeling, and was often engaged in prayer. Rev. Mr. Hermann sympathized with her in this, and with the commencement of the rapping in his room, he experienced an involuntary disposition to pray." (See Mr. Rogers's work, where many such cases are given.)
In elucidation of the effect of glass, sand, gravel, &c., upon her organism, we will state an additional fact, as related by her physician: "On the 21st of April, Dr. K. was at the house of Mrs. H. The window being open, he saw a quantity of gravel come in the window, which he not only saw, as he says, 'but picked it up!' To be certain that no one threw it in, he immediately looked out. On comparing it, he found it to be such gravel as lay in the front of the house."
"Now, let the phenomena we have related be put side by side with those which occurred at the house of Rufus Elmer, in Springfield, Massachusetts, on the 5th of April, 1852, as witnessed by Professor Wells, of Cambridge, and others, and alleged to be the work of spirits.
First. The table was moved in every possible direction, and with great force, when no cause of motion could be perceived.
Second. The table was forced against each one present so powerfully as to move them from their positions, together with the chairs they occupied, in all several feet.
Third. Mr. Wells and Mr. Edwards took hold of the table in such a manner as to exert their strength to the best advantage, but found the invisible power, exercised in the opposite direction, to be quite equal to their utmost efforts.
Fourth. In two instances, at least, while the hands of all the members of the circle were placed on the top of the table, and while no visible power was employed to raise the table, or otherwise to move it from its position, it was seen to rise clear of the floor, and to float in the atmosphere for several seconds, as if sustained by a denser medium than the air.
Fifth. Mr. Wells was rocked to and fro with great violence, and at length it poised itself on two legs, and remained in this position for some thirty seconds, when no other person was in contact with the table.
Sixth. Three persons, Messrs. Wells, Bliss, and Edwards, assumed positions on the table at the same time, and while thus seated, the table was moved in various directions.
