Mr. Seward to Lord Lyons.

My Lord : I have the honor to acknowledge the receipt of your note of yesterday, in which, under the instructions of your government, you ask to be informed of the grounds upon which the British brigs Volante, of Jersey, and Dashing Wave, of Liverpool, have been captured by United States cruisers at Matamoras, and to state that I have made application to the Secretary of the Navy for the desired intelligence.

I have the honor to be, with high consideration, your lordship’s obedient servant,

WILLTAM H. SEWARD.

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