[D8963ABA], Letter from Michigan Phonograph Co, John L Butterfield to Thomas Alva Edison, June 24th, 1889

Editor's Notes

"I am very much obliged to you for the musical cylinders; they came safely through reaching us to-day.### I have written to Mr. Rowell asking him to visit your laboratory and prepare a cylinder for the Grand Rapids meeting.### Is there a reliable account published of your discovery of the Phonograph principle, and your early experiment connected with it. If there is will you please advise me where it may be had, as I shall, no doubt, be asked questions on that line and would like to be better informed.### Again thanking you for the cylinders, I am,"
