Mr. Seward to Lord Lyons..

My Lord: Credible information having reached this department that John C. Braine, H. A. Parr, John Parker Locke, alias Vernon Gr. Locke, David Collins, George Robinson, John Wade, and others, have committed piracy and murder on board the United States steamer Chesapeake, while that vessel was on her way from New York to Portland, in Maine, and that they have taken refuge in the British provinces of New Brunswick or Nova Scotia, I have the honor to request that, pursuant to the 10th article of the treaty of Washington, they may be delivered up for trial in the United States.

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

WILLIAM H. SEWARD.

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