Abstract:
Responding to request from mutual acquaintance, Mr. Berry, to reach out to Seitz. Berry had seen an exhibition put on by the company and after examining the medical devices attempted to connect Seitz and the company. Seitz had not yet responded to circulars sent to him by the company, so they are reaching out yet again to inform him that they have been working to improve the instrument. "We now feel confident enough to guarantee it [the battery] for one year." On printed letterhead reading "The Electric Aurophone Co. Owners and Manufacturers of Ehrlich’s Patent Electric Aurophone, An Aid to Hearing and an Electrical Treatment for the Permanent Relief of Deafness."
