The possible dates are established by the ‘Down’ headed notepaper on which this letter is written (the printed address was crossed out by the amanuensis and is not reproduced here) and by the handwritten address. The printed notepaper is of a sort that CD used from November 1874, and his daughter Henrietta Emma Litchfield lived at 2 Bryanston Street, London, from 1872; by February 1878, the address had changed to 4 Bryanston Street as a result of renumbering (Correspondence vol. 26, letter to James Torbitt, [28 February 1878]). Between November 1874 and February 1878, CD made three visits to 2 Bryanston Street; the Wednesdays during these visits on which this letter could have been written are 9 December 1874, 15 December 1875, and 10 January 1877.
