Mr. F. W. Seward to Mr. Campbell
Sir: The President having nominated you, and the Senate confirmed your appointment, as envoy extraordinary and minister plenipotentiary of the United States to the republic of Mexico, I transmit herewith your commission in that character.
If you accept the commission you will be pleased to execute the enclosed oath as required by law, and return the same to this department. As it is desirable that you should proceed to your mission without any delay that can be avoided, the department would like to be informed when it will be convenient for you to start.
You will also inform the department of the State in which you were born, and of that of your residence when appointed.
I am, sir, your obedient servant,
Lewis D. Campbell, Esq., Washington, D. C.
