[D7829T], Letter from Albert Cable Hale to Thomas Alva Edison, February 28th, 1878
Editor's Notes
Received tin foils, they were very useful in Hale's efforts to describe phono -- suggests an improvement of using glass or porcelain rather than metal speaking horn TAE marg: Mr. E directs me to say that he has now attained perfect reproduction-- & that your suggestion of a porcelain funnell is good he will try it and thanks you for the suggestion.
