Hon. Secretary of StateDear Sir.
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–2

1Abraham Lincoln wrote and signed this letter and wrote and initialed the post script.
2Richard W. Thompson’s name does not appear in the official registers of the officers and agents of the government for 1849, 1851, and 1853, so apparently he did not receive an appointment.
