Papers of John Adams, volume 21

ENCLOSURE
Gentlemen of the Senate and of the House of Representatives. March. 19th. 1792

For the sake of Justice, and for the honor of your Country, hear my Complaints, and do me that justice, which every freeman, in a free Country is entituled to.— That I have discovered Longitude, is a truth, that I can easily prove, if I can but obtain an impartial hearing, face to face, with the Man, that would with Art and falshood deprive me of the Credit and benefit of my discovery, but which by your Justice of impartiality I can obtain.

While I understood, that he was to discover Longitude, by the variation of the Compass, I only smiled at his ignorance; but when I observed to Mr. Page, that I could ascertain the Longitude, within a quarter of a degree, by the dipping needle, as certainly as he could a whole degree, by the variation of the Compass; as the Inclination of the Load Stone, was four times as much as its declination. True says Mr: Page, but he is to take a dipping needle with him.2 Then, said I, he intends to find out Longitude, by my plan, & give assurance that he did it by his own.

Surely the Representatives, of the Freemen of North America, will not suffer such fraud to prevail, but will do justice, to every one 113 of their fellow Citizens, according to their veracity, and abilities— Your compliance with this request, will do honor to yourselves, and justice to / Your most obedient & / very humble Servant

John Macpherson

N: B. I do not wish to obtain Sea Otters and Seal Skins &c by deceiving my Country; nor to run it to the expence of such a Voyage, My only desire is, to be sent a passenger to France, in the Character of a Gentleman, that I may have an opportunity, by crossing the Atlantic, to prove my allegations, and to make the second discovery of my improvement, to your good Ally the King of the French—

I am respectfully, Yours as above,—

John Macpherson
