Dr. Hull was full of questions about Ida? how she appeared; what relations had established themselves between Miss Ludington and her; whether she showed any memory whatever of her disembodied state; whether the knowledge of the mystery involving her seemed in any way to affect her spirits or temper, or to set her apart in her own estimation from others, with many other acute and carefully considered queries calculated to elicit the facts of her mental and spiritual condition? "There is one point," said the doctor, "about which I am particularly curious. How is it with her memory of her former life on earth? Does it break off suddenly, as if on some particular day or hour her spirit had made way for its successor, and passed away from earth?" "On the contrary," said Paul, "she has intimated, in talking over the past with Miss Ludington, that the memory of her life on earth is clear and precise during its earlier portions, but that toward the last it grows hazy and indistinct." "Exactly," broke in the doctor. "Just as if her personality had a little overlapped and melted at the edge into that which followed it. Yes, it is as I thought it might be. Youth, or childhood, or infancy, or any other epoch of life, does not abruptly cease and give place to another. Their souls are gradually withdrawn as the light is withdrawn from the sky at evening, and a space of twilight renders the transition from one to the other perceptible only in the result, not in the process. This I think is a view of the matter, that is corroborated by the testimony of our own consciousness, don't you, Mr. De Riemer?" "On the whole, yes," replied Paul. "And still, if she had said that the severing of her personality from that which succeeded it was sharp and clearly defined, so that up to a certain day, or even hour, her memory was full and distinct, and then became a blank, there are passages in my own experience, and I think in that of many persons, which her statement would have made comprehensible. I think that to many, perhaps to all persons of reflective turn of mind, there come days, even hours, when they feel that they have suddenly passed from one epoch of life into another. A voice says in their hearts with unmistakable clearness, 'Yesterday I was young; to day I am young no longer.' There is also sometimes a day, I think, when the middle-aged man becomes suddenly aware that he is old. Who shall deny the truth of these intuitions, or say that it is not in that very day and hour that the spirit of youth or of maturity takes its flight?" "By the way," said Dr. Hull, "have you ever speculated on the probable number of the souls of an individual? It is an interesting question."
