Mr. Seward to Lord Lyons.

My Lord: I have the honor to acquaint you that the United States attorney at Key West, in a letter to this department of the 11th instant, represents that the British steamer Adela and her cargo were condemned as lawful prize by the district court there in February last, after a long delay, prayed for by the claimants, to enable them to introduce further proof from England. Mr. Boynton says nothing about the sale of the vessel which was the subject of your note to this department of the 7th instant, but it is presumed the sale may have been made pursuant to the decree of condemnation.

I have the honor to be your very obedient servant,

WILLIAM H. SEWARD.

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