"In the cases on duplicating phonograms the Patent Office raises the point that the proces of [unclear] deposit is in a [unclear] since the reforged metal would meet the wax and destroy the record, or at least it strikes the examiner that such would be the result. He therefore requires a demonstration of the process. This request would be satisfied by showing a deposit made in vacuum upon a wax record, with an affidavit of yourself that it was so made. If you have a deposit of this kind that you can spare, please send it to us. ### Yours truly, Dyer + Seely
