3) ALS. "F. Berthollet." Three pages (of a bifolium with an integral address sheet) in French, 6.5" x 8.25", Arcueil; June 11, 1804. In this letter to Madame Vinneux, Madame Berthollet opens by speculating that passport troubles are being caused by "cette saison" [presumably meaning the contemporaneous political situation] and will seek information about the delay experienced by her friend in obtaining permission to travel. Mme. Berthollet was convinced her friend was on her way and assures her that she and her husband speak of her and "their second son," Déodat, at every meal. Meanwhile her husband has received a "new distinction" from the government that she describes as more of a burden than a privilege since they must outfit an "archbishop's house" with furniture, linens and all the rest [Claude Louis Berthollet was made a Grand Officier de la Légion d'Honneur in 1804].
