Mr. Corwin to Mr. Seward.
Sir: I have the honor to acknowledge the receipt of your despatches Nos, 43, 44, and 45, with the two treaties between the United States and Mexico lately ratified at Washington. The ratifications will be exchanged to-morrow, and the next day Mr. Plumb, with Captain Shufeldt, will leave for Vera Cruz.
