Manuscripts/Mixed Material Letter from Alexander Graham Bell to Samuel P. Langley, November 26, 1901
Nov. 26, 1901.
Prof. S. P. Langley,
Secretary Smithsonian Inst.,
Dear Prof. Langley: —
I have just returned to the city and find your note of Nov. 19 awaiting me. There have been notable advances in wireless telegraphy during the present year, also developments of the Telephonograph. I cannot lay my hand upon the references at the present moment, but will look the matter up at an early date. Will also answer more specifically your query relating to the article on Pupin's invention, in Everybody's Magazine, after I have read it.
I haven't time just now, to do anything more than let you know that I am in town.
