<Friday, December 6, , a note in the third person. Requests Franklin’s company at dinner next Sunday to meet Mlle. Biheron and Dr. Ingenhousz before the latter’s departure.>
6. During BF’s second mission Dec. 6 fell on a Friday in 1765 and 1771, and the latter was almost certainly the year. BF’s papers first refer to Mlle. Biheron and Ingenhousz in 1767–68 (above, XIV, 4; XV, 115); she was in town at some time during 1771, he was there on Nov. 28, and BF expected to be back from the north by Nov. 30.
