My trip across and my subsequent arrival in Paris were without any events of particular interest, and one bright morning in the early summer I found myself comfortably lodged in the house where I had previously boarded while a student. Connected with my rooms, which were at the top of the house, was one of considerable size that I had formerly used as a laboratory, and this I now set about fitting up to serve the same purpose. The daylight found its way into the room through a skylight, and though admirably suited for an artist's studio, it answered my purpose equally as well. I had collected many new instruments and appliances by dint of days spent in shopping, and was anxious to begin work in earnest, when one evening, as I glanced through the columns of a newspaper, my attention was arrested by an article of particular interest. This set forth the great and increasing demand for a substitute for glass, one which would answer the purpose in every respect, and at the same time be indestructible and a good conductor of sound. The article concluded with an enumeration of the many uses for which such a substitute would be invaluable, hinting at the enormous financial possibilities which would be open to the inventor. The more I considered the matter, the more desirous I became to test several theories which forthwith presented themselves to my mind, and the next morning found me determined to begin my experiments at once. In theory, I saw the solution of the problem in artificially producing increased atomic motion, and with that object in view I went to work. My experiments involved me in weeks of hard work, and it was toward the end of the summer before I could admit having had any important results. I now had a substance resembling glass in appearance, though vastly different in composition, which I made into a film, extremely thin and highly sensitive to vibrations. Running through this film were slender wires made of various metals, about one inch apart, which served not only to give rigidity to the film, but also to conduct a current of electricity through it, engendering a high state of atomic agitation. The current was controlled by a small switch placed in a heavy box-like frame, which bounded the film on its four sides and contained the batteries, coils, etc. To this were attached four legs, supporting it about the height of an ordinary table from the floor. The whole device measured about seven feet square. This film substance contained certain elements which I had found to be necessary to secure the desired intensity of agitation. It had taken me almost a month to secure the fine quality I desired, and I looked forward to the test with the feeling that results would prove that I was nearing the goal, if I had not actually attained it.
