The manuscript is an autograph letter written in the hand of Philippe Antoine de Claris. It requests the addressee to provide an update on his current situation and that of Claris’s sister, while also outlining the symptoms of Claris’s latest physical ailment. According to T. D. N. Besterman, the manuscript’s foliation is 115. Additionally, T. D. N. Besterman remarks that ‘Caussy, p. 25, places this letter at the beginning of April 1775, ED1 tentatively in December 1773; the latter date is impossible since Florian was then a widower; a comparison with the references in D19248, D19311 to Cabanis and mme de Florian points to the date proposed above.’
