IN commencing another chapter, I take the opportunity of repeating what I have said before, viz., that in treating of these phenomena, I find it most convenient to assume what I myself believe—that they are to be explained by the existence and appearance of what are called GHOSTS; but in so doing, I am not presuming to settle the question: if any one will examine into the facts and furnish a better explanation of them, I shall be ready to receive it. In the meantime, assuming this hypothesis, there is one phenomenon frequently attending their appearance, which has given rise to a great deal of thoughtless ridicule, but which, in the present state of science, merits very particular attention. Grose, whom Dr. Hibbert quotes with particular satisfaction, says: “I can not learn that ghosts carry tapers in their hands, as they are sometimes depicted; though the room in which they appear, even when without fire or candle, is frequently said to be as light as day.” Most persons will have heard of this peculiarity attending the appearance of ghosts. In the case of Professor Dorrien’s apparition, mentioned in a former chapter, Professor Oeder saw it, when there was no light in the room, by a flame which proceeded from itself. When he had the room lighted, he saw it no longer, the light of the lamp rendering invisible the more delicate phosphorescent light of the spectre: just as the bright glare of the sun veils the feebler lustre of the stars, and obscures to our senses many chemical lights which are very perceptible in darkness. Hence the notion, so available to those who satisfy themselves with scoffing without inquiring, that broad daylight banishes apparitions, and that the belief in them is merely the offspring of physical as well as moral darkness. I meet with innumerable cases in which this phosphorescent light is one of the accompaniments, the flame sometimes proceeding visibly from the figure; while in others, the room appeared pervaded with light, without its seeming to issue from any particular object. I remember a case of the servants in a country-house, in Aberdeenshire, hearing the door-bell ring after their mistress was gone to bed; on coming up to open it, they saw through a window that looked into a hall that it was quite light, and that their master, Mr. F——, who was at the time absent from home, was there in his travelling dress. They ran to tell their mistress what they had seen; but when they returned, all was dark, and there was nothing unusual to be discovered. That night Mr. F—— died at sea, on his voyage to London. A gentleman, some time ago, awoke in the middle of a dark winter’s night, and perceived that his room was as light as if it were day. He awoke his wife and mentioned the circumstance, saying he could not help apprehending that some misfortune had occurred to his fishing-boats, which had put to sea. The boats were lost that night.
