MS (DLC: TJ Papers, 233:41784); in Clay’s hand; undated; endorsed by TJ: “Thermometrical Diary. mr Clay 1811. Jan 1. to Feb 26.”

Clay probably made these observations at his home, Ivy Hill, and sent them to TJ as he neared the end of his 30 Jan.–28 Feb. 1811 visit to nearby Poplar Forest (MB description begins James A. Bear Jr. and Lucia C. Stanton, eds., Jefferson’s Memorandum Books: Accounts, with Legal Records and Miscellany, 1767–1826, 1997, The Papers of Thomas Jefferson, Second Series description ends , 2:1263).

1. Here and throughout, the “S” stands for “Sunday.”
