WASHINGTON, _March 12, 1822_.
_To the Senate and House of Representatives of the United States_:
I lay before the Senate the copy of a supplementary report, made by
William Lambert, in relation to the longitude of the Capitol from
Greenwich, in pursuance of a joint resolution of the two Houses of
Congress of the 3d of March, 1821, and I subjoin an extract from the
letter of Mr. Lambert submitting that report.
