36 INTERIOR VISION. subject the attention itso richly deserves. The task of bringing its scattered ends together has been imperfectly performed herein perhaps; yet have I fearlessly stripped it of the garb of mystery purposely thrown around it by pseudo-mystics, charlatans, and the rank impostors who abound on all hands, and bring odium and disgrace on a matter whereof they are wholly ignorant. Mirror-secing is unquestionably a fact and a science, however some may failin their efforts to see, and despite the sneers of others who are wise in their own conceit, know nothing whatever of the principia of that which they so glibly deride and condemn, and who have not the kind or quality of brains or mental power possessed by those who are better qualified than they are. Mirror-seeing is but another mode and phase of clairvoyance; it is the self-same power, reached by a different road, and different processes, but is, and can be, carried to a far greater degree of perfection by many persons, while others totally and wholly fail. And here I strongly advise all to refrain from the expense and trouble of mirror-experimentation, who have no tendencies of an interior magnetic or mesmeric character. But possessing these, it is highly probable that satisfactory results will follow a proper trial. ; In the Master Passion, I promised to make a statement in reference to the Davenport Brothers so-called mediums. They are not worth the ink. I once wrote a book for them from so-called facts and data which they furnished me, and which I believed were true as I certainly believed them to be genuine media. I am now satisfied that the data furnished were wholly untrue, and the alleged facts entirely imaginary, in a word, I believe that the D. B.'s are dead beats; in other words, that they are skilful jugglers, without the slightest real spiritual power about any of their performances, save it be ‘‘ ardent spirits.” I am free to confess that for years the brothers deceived me. I acknowledge the fact. Why did you not apply certain oecult power you are said to possess, to the investigation? I reply: Never thought of it for a long time; but eventually became convinced it had been better to have done so years ago. But better late than never. These, then, are my reasons for writing this book. P. B. R. The famous Dr. Dee, of London, and thousands of others, since and before him too, used a plate of polished cannel coal (which identical plate Ihave myself seen in the British Museum), and other instrumentalities also, as a means whereby to scan and cognize mysteries otherwise wholly unreachable. Some sturdy matter-of-fact people in these material days, wherein a great deal of pseudo-miracleism is current, along with a very little that is real and genuine, are apt to ridicule and laugh at the idea that a mere physical agent can enable one to penetrate the floors of the
