I want to know the answer to the following question:
Bell's patent was for the method and what for transmitting vocal and other sounds telegraphically?
All the background I'm provided with is that "Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16]". Is that enough to answer the question?
