Philadelphia, July 12th. 1806.
With respect I take this method of communicating to You, the disagreeable information, that an enemy at present appears to prevail mystically in an endeavorment of killing me mystically by electricity or magnetism, and it has prevail’d on the Soldiers on the 4th. of July; there has also been contempt spoken against you of persons in my presence, I expect the is a general endeavor against your Government.
I am your most Obedient Servant,
