"On Saturday, March 9th, I had written a somewhat impatient note to a friend, accusing her of having, on her return from a two months' absence on the Continent, spent ten days in London without paying me a visit. I was not, therefore, surprised, when on Sunday evening she appeared before me in the Crystal, but could not understand why she should hold up, with an air of deprecation, what appeared to be a music portfolio. On Monday I received an answer, written the previous day, pleading guilty to my charge, but urging, in excuse, that she was attending the Royal Academy of Music, and was engaged there during the greater part of every day. This intelligence was to the last degree unexpected, for my friend is a married woman, who has never studied music in any but amateur style, and who, according to the standard of most ladies of fashion, had "finished her education" some years ago. I have since ascertained that she, in fact, carries a portfolio corresponding with the sketch I made of that seen in the vision." (No. 64.) The simplest explanation of this case would be the assumption that our informant had at some time or other cursorily heard of her friend having again taken up music. The whole thing would then be a revived memory; and the agreement in appearance of the portfolio seen with the real portfolio, an accidental coincidence. But this presumption being excluded, psychologists who believe in the possibility of telepathic communication might propose a different explanation. In this way. The lady's friend, in writing her note of excuse, is vividly thinking of her work, which is to her to a certain extent represented by her portfolio, and conveys this picture to the receptive sub-consciousness of the other lady. There the image lies latent until it is translated into sensory life through the agency of the magic mirror—the very process with which we have at a previous place become acquainted, and will more exactly explain further on. The question, therefore, is reduced simply to the truth of the premise first assumed—namely, telepathic communication; and all that we can at present say, is, that it is considered as an actual fact, upon the basis of personal experience, by many prominent investigators, but is rejected by the majority as undemonstrated. For our part, we admit that an hypothesis of this kind would prove to be very useful, since reports similar to the last mentioned one, have recently been published in great numbers. We select as an illustration the following note by Mrs. L. M., from the Proceedings of the American Society for Psychical Research:
