By an accident, in some respects not unlike the one which drew Roentgen's attention to the light by whose aid we have learned to look into and through opaque bodies, I (myself an accident, an appearance on and soon to be a disappearance from the illuminated surface of the earth) have discovered eternal laws, by whose aid we shall be able to comprehend much of what has heretofore been as a closed book to us, regarding our physical and psychical nature and the exercise of our faculties and functions. During my endeavors to overcome the difficulties which my German tongue offered to the perfect pronunciation of the English "r" sound, and during an almost frantic effort on one occasion at so doing, I was amazed by the fact that while one "r" came to the surface from over and above the tongue, another made its appearance from under and beneath the same. The latter was the "r" of the voice of the œsophagus. Of all this, however, I have spoken at length in my previous publication. Though it occurred to me at once like a flash that this was a revelation of the greatest importance, its real significance was only made clear to me in the course of time. No matter how I view it, as time progresses it assumes greater and greater proportions. There is no event in the history of man which appears to me to be of greater significance. Through this "accident" I was induced to look closer and closer into my inner nature, where, to my amazement, I found that a world, apparently silent and mysterious, and supposed to be unapproachable, was the abode of numberless physical and psychical phenomena, clearly defined and definable. The "r" which came to the surface from beneath my tongue by way of the œsophagus was the cathode, the negative end of this sound. The _product_ of its combination with the _simple_ "r" (which came to the surface from over and above the tongue by way of the trachea) I had hitherto produced when attempting to speak English, was the _vocal_ "r" sound of the English language; the "r" I had hitherto produced having been the anode--the positive and first part of this sound only. As Roentgen's cathodic light has illuminated the physical body, so have cathodic sounds illumined for me the spiritual body of my mundane existence. I am endeavoring to show my fellowmen this "new light," whose lustre, also invisible on ordinary occasions, when once seen is so great that it will never again fade from the memory of the beholder. As time progresses, it will continue to penetrate ever more deeply into regions hitherto considered to be impervious to any kind of light; regions whose phenomena have been called supernatural, or, at least, beyond the sphere of the knowledge of man. All other anodes or cathodes of which we have obtained any knowledge belong to physical phenomena only. The cathode I have discovered belongs to our spiritual life, being a part of a living vocal sound.
