Mathieu ORFILA (1787–1853), physician and chemist. Letter from the author (L.A.S.), Paris, June 14, 1836, to Gaultier de Claubry, a teaching assistant at the École Polytechnique; 1 page, in-8 format, on University of France letterhead, with return address. “The City Council committee in charge of the revenue budget is meeting on Thursday morning at seven o’clock, and the session will last until 11:30 a.m. As the rapporteur for this committee, I must attend the session and will therefore not be able to be at home as I had told you yesterday.” Orfila therefore asks his colleague to reschedule their meeting.
