Diary of John Quincy Adams, volume 1
Remain'd at home all the morning, writing Letters1 for Europe, as the british Packet is to sail the day after tomorrow. Dined with Doctor Crosby, and spent the evening with Mr. Searle. Return'd at about 9 o'clock.
JQA to AA2, 1–8 Aug. (Adams Papers), is the only extant letter written (in part) on this date.
