Holmes attributed the remark "Good Americans, when they die, go to Paris" to "one of the wittiest of men". Later writers have attributed the saying to friend and fellow Saturday Club member Thomas Gold Appleton. In 1859, Ralph Waldo Emerson, also a member of that club, recorded in one of his journals, "T. Appleton says, that he thinks all Bostonians, when they die, if they are good, go to Paris." Emerson in His Journals, ed. Joel Porte (1982), p. 486. Neither sentence has been found in the published writings of Appleton, but the remark may have been made in the presence of Holmes and Emerson. Oscar Wilde used the Holmes version in The Picture of Dorian Gray (1890), p. 75 (Complete Works, vol. 4, 1923), and A Woman of No Importance (1893), p. 180 (Complete Works, vol. 7, 1923).

Temenidæ Frag. 734
Context: When good men die their goodness does not perish,
But lives though they are gone. As for the bad,
All that was theirs dies and is buried with them.
