To be sure, not every one spends twenty-five years on the elaboration of some twisted fancies. Most of my correspondents write the monumental thoughts of their systems with decisive brevity. A physician informs me that every thought and act of our lives is transfixed on the etheric vapours that surround our earth, and that it is therefore only natural that a clairvoyant is able to see those fixed events and write them down afterward from the ethereal inscriptions. Another tells about his discovery that the human body is a great electrical magnet. I am the more glad to make this fact widely known, as the author writes that he has not given it to the public yet, as he is not financially able to advertise it. Yet he himself adds that after all it is not necessary to advertise truth. On eight quarto pages he draws the most evident consequences of his discovery and shows how he is able to explain by it the chemical change of each cell in the brain and to prove that “foolish so-called spirits are simply electrical demonstrations.” “I can demonstrate every current, nerve cell, and atom of the human body. It may seem strange to you that I claim so much, but with the induction every investigation has been so easy for me. I have never been puzzled for any demonstration yet, but I am still searching for more knowledge. Yours for investigation....” I may say that this is a feature common to most of my correspondents of this metaphysical type. They are never “puzzled.” Nearly related to this type of theories are the systems of astrology; and in our upper world very few are really aware what a rôle astrology is still playing in the intellectual underworld. Some of the astrological communications I receive periodically go so far beyond my understanding that I do not even dare to quote them. But some of the astrological authors present very neat and clean theories which are so simple and so practical that it is almost a pity that they are absurd. For instance, I am greatly interested in the question of determining how far the mind of individuals is predisposed for particular vocations, and in the psychological laboratory we are busy with methods to approach the problem. The astrologers have a much more convincing scheme. My friend writes that he has observed “over two thousand cases wherein the dates of birth have been the means to give the position of the planets at the hour of birth, the purpose being to ascertain the influence they had on man. Now the furniture business calls for an artistic temperament, and after careful observation through birth dates it is found that the successful furniture men have the planet Venus in their nativities. But the Venus influence is prominent also in other lines of business such as art, jewellery, and in all lines where women's necessities are manufactured. Other planetary influences on success in business are: Saturn for miners, tanners, gardeners, clowns, and beggars; Mercury for teachers,
