 | | Alexander Graham Bell to Joseph Wehrle, April 16, 1885; Bell, "To whom it may Concern," April 25, 1885; Bell to Joseph Faber, April 25, 1885: all in "Faber's Talking Machine," Alexander Graham Bell Papers, Manuscript Division, Library of Congress. |
 | | Bruce says that Alexander and his father saw Faber's machine in London in 1863, but he seems to be confusing this with Wheatstone's machine. |
 | | Mary Henry to Alexander Graham Bell, May 2, 1883; receipt of purchase, May 2, 1883: both in "Mary Henry," Alexander Graham Bell Papers, Family Papers, Manuscript Division, Library of Congress. |
