Title

[MBLB4106], Letter from Charles Batchelor to Edward Hibberd Johnson, January 13th, 1882

Editor's Notes

Your phonograph article for Nov 17 1877 Sci Am was the first on the subject, so date of your "little handbook" must be wrong. We successfully tried the expt of pulling a strip through a groove to produce a note in July or Aug 1877. I know among our telephone drawings from July 1877 there's one showing phono used as telephone receiver.
