Count Wydenbruck to Mr. Seward.
Mr. Secretary of State: I have only been awaiting your return from your excursion to Raleigh to express to you my warmest thanks for the step you [Page 567] took on the 1st instant, immediately before your departure, in directing Mr. Campbell to repair to San Luis Po tosi. I feel convinced that no measure could have been adopted more in accordance with the desires of my court, with which I had again the honor of making you acquainted on the 28th and 29th of May, and that the presence of Mr. Campbell will not only prevent any act of violence towards Prince Maximilian, but will also insure his speedy release.
I avail myself of this opportunity to express to you, Mr. Secretary of State, the assurance of my highest consideration.
Hon. William H. Seward, &c., &c., &c.
