The final version of the Lettre à M. Dacier was published in late October 1822 by Firmin-Didot in a booklet of 44 pages with four illustrated plates. Thomas Young's work is acknowledged in the Lettre à M. Dacier, though early British critics such as James Browne alleged in 1823 that the acknowledgment was incomplete and that Champollion had plagiarised Young's work.
