Charles Williamos, fl. 1773-1785, soldier. Letters between Jefferson and Williamos in the Jefferson papers in the Library of Congress, written
in 1785 when both were in Paris, make it clear that Captain Williamos was an officer on half-pay in the British service. Jefferson
wrote to him: “
. . . you could not as yet be a citizen of it [i.e. our new republic]
as you had visited it only for two or three months since the peace, and were still as I had understood an officer on half
pay in the British service . . .
”
In his reply Williamos mentioned that he had served under General Lee in the last war.
The death of Captain Williamos, which occurred before February 8, 1786, on which date Jefferson mentioned it in a letter to Madison, was the cause of Jefferson’s consent to the translation of his
Notes on Virginia
into French. A full account of the incident, occasioned by Williamos’s copy of the
Notes having fallen after his death into the hands of a bookseller, will be found in several of Jefferson’s letters to his friends, written at that time.

Address to the Manufacturers of Pot and Pearl Ash.
New-York,
1791.
8vo. No copy has been located.
Not in Sabin.
Not in Smith.
This work is not listed in Evans, and no copy has been traced. It seems possible that the author may have sent his work to Jefferson in manuscript.
Jefferson’s copy was sent to him by the author who wrote from New York, June 27, 1791: “I take the liberty of offering for thy acceptance an address to the Manufacturers of Pot & Pearl-ash, containing an account
of the process &c according to the Principles of my Patent--Thou wilt observe my having succeeded in Canada, and by accounts
from those who have commenced opperating I am flattered to believe that the business is in a fair way of fully answering what
I have held out.
"After making some further arrangements here propose returning to Philadelphia when intend personally to wait on thee, and
hope I shall have it in my power to give farther satisfaction.”
