Diary of John Quincy Adams, volume 1
This day, being Term day,1 we went, with Mr. Jennings, and saw the procession of the Lawyers, and Judges to Westminster Hall; and we saw the four Courts; the Kings Bench, Common Pleas, Chancery, and Exchequer, all sitting. Dined at M: W. Vaughan's.
That is, the beginning of Michaelmas Term, one of four yearly sessions of English courts of law.
