substituting forty-five degrees instead of thirty-eight degrees, which
I had at first proposed as a standard latitude. I send you a copy of my
report for the Bishop, and another for M. Condorcet, Secretary of the
Academy of Sciences. By taking the second pendulum or rod of the same
latitude for the basis of our measures, it will at least furnish a
common measure to which both our systems will refer, provided our
experiments on the pendulum or rod of forty-five degrees should yield
exactly the same result with theirs.

The newspapers, as usual, will accompany the present, which is to go by
Mr. Barrett.

I have the honor to be, with great esteem and attachment, Dear Sir, your
most obedient and most humble servant,

Th: Jefferson.
