I placed this treasure carefully in a corner of my portmanteau, together with the parchment scrolls containing "The Electric Principle of Christianity," and the valuables recipes of Heliobas; and as I did so, I caught sight of myself in the long mirror that directly faced me. I was fascinated, not by my own reflection, but by the glitter of the electric gem I wore. It flashed and glowed like a star, and was really lovely--far more brilliant than the most brilliant cluster of fine diamonds. I may here remark that I have been asked many questions concerning this curious ornament whenever I have worn it in public, and the general impression has been that it is some new arrangement of ornamental electricity. It is, however, nothing of the kind; it is simply a clear pebble, common enough on the shores of tropical countries, which has the property of absorbing a small portion of the electricity in a human body, sufficient to make it shine with prismatic and powerful lustre--a property which has only as yet been discovered by Heliobas, who asserts that the same capability exists in many other apparently lustreless stones which have been untried, and are therefore unknown. The "healing stones," or amulets, still in use in the East, and also in the remote parts of the Highlands (see notes to Archibald Clerk's translation of 'Ossian'), are also electric, but in a different way--they have the property of absorbing DISEASE and destroying it in certain cases; and these, after being worn a suitable length of time, naturally exhaust what virtue they originally possessed, and are no longer of any use. Stone amulets are considered nowadays as a mere superstition of the vulgar and uneducated; but it must be remembered that superstition itself has always had for it a foundation some grain, however small and remote, of fact. I could give a very curious explanation of the formation of ORCHIDS, those strange plants called sometimes "Freaks of Nature," as if Nature ever indulged in a "freak" of any kind! But I have neither time nor space to enter upon the subject now; indeed, if I were once to begin to describe the wonderful, amazing and beautiful vistas of knowledge that the wise Chaldean, who is still my friend and guide, has opened up and continues to extend before my admiring vision, a work of twenty volumes would scarce contain all I should have to say. But I have written this book merely to tell those who peruse it, about Heliobas, and what I myself experienced in his house; beyond this I may not go. For, as, I observed in my introduction, I am perfectly aware that few, if any, of my readers will accept my narrative as more than a mere visionary romance--or that they will admit the mysteries of life, death, eternity, and all the wonders of the Universe to be simply the NATURAL AND SCIENTIFIC OUTCOME OF A RING OF EVERLASTING ELECTRIC HEAT AND LIGHT; but whether they agree to it or no, I can say with Galileo, "E pur si muove!"
