To John M. Clayton 
Dear Sir. July 4. 1849
I understand the name of our excellent friend Hon. R.W. Thompson, of Indiana, is before you for some diplomatic appointment. It needs no one to tell you who he is, and I wish to say, as matter of substance, and not of form merely, that I sincerely desire he may be successful. Your Obt. Servt A. LINCOLN
P.S. This letter is unsolicited by Mr. Thompson, and wholly voluntary on my part A.L.
