Title
[NV13111] Technical Note, November 16th, 1877
Editor's Notes
since Bell's telph works (weakly) with copper or mica instead of iron diaphram, thinks must be molecular action rather than large-scale e-m, so design a phone on this basis "a new advance in the art - hence patentable & gets clear of Bells fearful claims"
