From the notes of Dr. Catherine Perry: This letter sent most probably to Léon Daudet, in which Barrès corrects an error in a publication by Daudet, adding that "it's a consternation that [the newspapers] Le Petit Parisien and Le Rapporteur didn't say anything." By this Barrès probably means that they didn't mention Daudet's article. The publication by Daudet is probably in the newspaper L'Action Française, which he helped to found in 1908 and of which he was a co-director in 1913.
