In the first part of this century a book appeared in Germany which led to a very general and rather violent discussion of the whole subject. It was written by a Dr. Woetzel, whose mind had, no doubt, been long engaged in trying to solve mysteries like that of the future life, since he had early come in contact with strange phenomena. The father of a dear friend of his having fainted in consequence of receiving a serious wound, was very indignant at being roused from the state of perfect bliss which he had enjoyed during the time. He affirmed that in the short interval he had visited his brother in Berlin, whom he found sitting in a bower under a large linden-tree, surrounded by his family and a few friends, and engaged in drinking coffee. Upon entering the garden, his brother had risen, advanced towards him and asked him what had brought him so unexpectedly to Berlin. A few days after the fainting-fit a letter arrived from that city, inquiring what could have happened on that day and at that hour, and reciting all that the old gentleman had reported as having been done during his unconsciousness! Nor had the latter been seen by his brother only, but quite as distinctly by the whole company present; his image had, however, vanished again as soon as his brother had attempted to touch him (Woetzel, p. 215). From his work we learn that he had begged his wife on her death-bed to appear to him after death, and she had promised to do so; but soon after her mind became so uneasy about the probable effects of her pledge, that her husband released her, and abandoned all thoughts on the subject. Several weeks later he was sitting in a locked room, when suddenly a heavy draught of air rushed through it, the light was nearly blown out, a small window in an alcove sounded as if it were opened, and in an instant the faint luminous form of his wife was standing before the amazed widower. She said in a soft, scarcely audible voice: "Charles, I am immortal; we shall see each other again." Woetzel jumped up and tried to seize the form, but it vanished like thin mist, and he felt a strong electric shock. He saw the same vision and heard the same words repeatedly; his wife appeared as he had last seen her lying in her coffin; the second time a dog, who had been often petted by her, wagged his tail and walked caressingly around the apparition. The book, which appeared in 1804, and gave a full account of all the phenomena, met with much opposition and contempt; a number of works were written against it, Wieland ridiculed it in his "Euthanasia," and others denounced it as a mere repetition of former statements. The author was, however, not abashed by the storm he had raised; he offered to swear to the truth of all he had stated before the Great Council of the University of Leipzig, and published a second work in which he developed his theory of ghosts with great ability. According to his view, the spirits of the departed are for some time after death surrounded by a luminous essence, which may, under peculiarly favorable circumstances, become visible to human eyes, but which, according to the weakness of our mind, is generally transformed by the imagination only into the more familiar form of deceased friends. He insists, besides, upon it that all he saw and heard was an impression made upon the outer senses only, and that nothing in the whole occurrence originated in his inner consciousness. As there was nothing to be gained for him by his persistent assertions, it seems but fair to give them all the weight they may deserve, till the whole subject is more fully understood.
