As I thought it probable Mr Priestly might have a Copy, I requested him to Spare it, I inadvertently mentioned your name, & have received a Copy not from him, but from Dr Priestly, who requests you will favor him by the acceptance of it—Mr Dufief being out of Town, I wish to know whether any person here has directions how to forward such objects to you, Should I in the interim meet with a Safe opportunity to Washington, I shall Send it forward
