No. 80.--From MRS. GREIFFENBERG and MRS. ERNI-GREIFFENBERG. Mr. F. C. S. Schiller, through whom the account was obtained, tells us that he heard the story in October 1890 from the two percipients. The following account was put together by him from an account (which he also sent us) written by Mrs. Erni-Greiffenberg, and various conversations which he had with both ladies on the subject. He afterwards obtained their signatures to it. Neither of them has had any other hallucinatory experience. "_December_ 14_th_, 1890. "In the beginning of the summer of 1884 we were sitting at dinner at home as usual, in the middle of the day. In the midst of the conversation I noticed my mother suddenly looking down at something beneath the table. I inquired whether she had dropped anything, and received the answer, 'No, but I wonder how that cat can have got into the room?' Looking underneath the table, I was surprised to see a large white Angora cat beside my mother's chair. We both got up, and I opened the door to let the cat out. She marched round the table, went noiselessly out of the door, and when about half-way down the passage turned round and faced us. For a short time she regularly stared at us with her green eyes, then she dissolved away, like a mist, under our eyes. "Even apart from the mode of her disappearance, we felt convinced that the cat could not have been a real one, as we neither had one of our own, nor knew of any that would answer to the description in the place, and so this appearance made an unpleasant impression upon us. "This impression was, however, greatly enhanced by what happened in the following year, 1885, when we were staying in Leipzig with my married sister (the daughter of Mrs. Greiffenberg). We had come home one afternoon from a walk, when, on opening the door of the flat, we were met in the hall by the same white cat. It proceeded down the passage in front of us, and looked at us with the same melancholy gaze. When it got to the door of the cellar (which was locked), it again dissolved into nothing. "On this occasion also it was first seen by my mother, and we were both impressed by the uncanny and gruesome character of the appearance. In this case, also, the cat could not have been a real one, as there was no such cat in the neighbourhood."
