Mr. Seward to Lord Lyons.

My Lord: Referring to the correspondence which has taken place between us relative to the capture of the schooner Mount Blanc, I now have the honor to enclose to you, for your information, the copy of a letter, of the 2d instant, from the attorney of the United States for the southern district of Florida, from which it will be seen that that vessel has been restored to the master and claimant.

I have the honor to be, your very obedient servant,

WILLIAM H. SEWARD.

Right Hon. Lord Lyons, &c., &c., &c.
