MS (DLC: TJ Papers, 80:13924); in an unidentified hand; undated; endorsed by TJ. MS (VtNN: Partridge Papers); in a bound volume of Partridge manuscripts; in an unidentified hand; undated. Printed in Washington Daily National Intelligencer, 10 Sept. 1816, with the addition of altitudes for Hempstead Harbor Hill in New York and three points in the Highlands of Navesink in New Jersey.
In February 1812 Jonathan Williams presented an earlier version of Partridge’s calculations to the American Philosophical Society, and in that form they were subsequently published in Transactions, new ser., 1 (1818): 147–50. Correspondence from Partridge to Williams and tables of these earlier calculations can be found in InU: Williams Papers.
,TJ noted in a manuscript revision to the query on mountains in his Notes on the State of Virginia composed sometime after November 1815, that “The highest of the White mountains in N.H. by barometrical estimate made by Capt Partridge was found to be 4885.f. from it’s base, and the highest of the Catskill mountains in N. York 3105. feet” (Jefferson, Notes on the State of Virginia [London, 1787; no. 4167; , 7 (no. 365); TJ’s copy in ViU, with revisions, including this one, tipped in between pp. 28 and 29]).
1. Thus in manuscript, but the correct figure should be either 2,428 for the altitude above sea level or 1,726 above the base.
2. Manuscript: “from of.”
