To Thomas Jefferson from James Sullivan, 8 January 1799
From James Sullivan
Boston January 8th 1799
Sir
One Mr Dearborn of this Town whom I conceive to be a natural Machanic, carries this letter to Philadelphia and hopes to have the honor to deliver it to you. His object is to gain by Patents an exclusive priviledge in several inventions among which are a perpendicular wind-Mill on new & useful principles, a Steelyard calculated to prevent fraud—a Trigonometrical Instrument useful in measuration & drawing Machine. I encourage him that he will certainly receive your countenance if he merits it—
You will allow me the honor to assure you that I am with sentiments of high respect your Most humble servt
Ja Sullivan
