Letter : [n.p.], to Mme. Denis, Marie Louise Mignot, 1768 Dec. 17.

Besterman noted that a letter to Mme. Denis dated the previous day (1768 Dec. 16; no. D15369 in the edition) was also in the Morgan's collection, but he was in error; the letter dated 1768 Dec. 16 was in a private collection as of 2021.
