Count Wydenbruck to Mr. Seward.

Mr. Secretary of State: I have just had the honor to receive your obliging communication of this day, and I hasten to express to you my very best thanks for it. Although I hope to have the honor of paying you my respects this evening, I did not wish to defer this expression of my acknowledgment, and hope that you will further favor me with any intelligence that you may receive as to the subject on which my court and myself are so deeply interested.

I have the honor to remain, Mr. Secretary of State, with the highest consideration, your obedient servant,

WYDENBRUCK.

Hon. William H. Seward, &c., &c., &c.
