Jean-Baptiste SAY (1767–1832). Autograph letter, Paris, Thursday, the 11th [1819?], to Mr. Voizelle at the Athénée; 2 pages, in-8 format, address with red wax seal (broken). He requests “two tickets for Benjamin Constant’s lecture on Saturday. I would be very grateful.” In a long postscript, he complains: “At my last lecture, I had trouble finishing my speech because of the stuffy atmosphere”; it would be necessary “to have two or three windows opened from 4 to 7 o’clock. The time before last […] I had them opened, and I felt much better for it, as did the audience”… Enclosed is a receipt (PA.S.), Paris, March 19, 1819, for 500 francs received from the administrators of the Athénée, representing fees for his course for the year.
