Title: [MBSB21361], Letter from Thomas Alva Edison to Scientific American, November 1879
Editor's Notes: Regarding Lockwood letter to Sci Am: "his statement that the scientific men of Europe have supportedd the claim of Hughes that the microphinic action is different from the carbon telephone, is absolutely false, and as a fact just the contrary is the case." Also, Patent Office has declared Blake transmitter an infringement; not the slightest difference from my carbon transmitter.
