Mr. Seward to Lord Lyons.

My Lord: This department is in possession of authentic information that among the persons who recently committed piracy and murder on board the United States steamer Chesapeake were two named Braine and Parr, respectively, and that they have taken refuge in the British province of New Brunswick or Nova Scotia. As it is desirable that they should be detained there until the formal affidavits can be forwarded with a view to their extradition for trial in this country, I will thank you to request her Majesty’s authorities to do anything which can be legally done for that purpose.

I have the honor to be, with high consideration, my lord, your obedient servant,

WILLIAM H. SEWARD.

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