We were talking about the playback of the Phonautograph plates. Anyway somwhere in the conversation, I had mentioned the authenticity of the Walt Whitman cylinder, and how most of the collector community was saying it was a fraud, and not real. They said it was authentic, and were not aware that it was in question. And I still came to an iconclusive myself because I myself made a cylinder copy of the poem and the result was not that much different than the supposed fake. I used a glass diaphragm and original blank . > ----------------- The analysis of the 'Whitman' cylinder was published in APM years ago - if they (Jennifer/Judith) want a copy of the details, just let me know. Roscoe Haley was very careful never to show anyone the actual wax cylinder, and the eal to sell it to Yale fell through on that account.
