Mr. Seward to Lord Lyons.

My Lord: I have the honor to acknowledge the receipt of your communication of the 5th instant, in relation to the case of the master and crew of the British schooner Sylvanus, and to inform your lordship that I have called upon the Secretary of the Navy and the United States marshal at New York for information upon the subject. When their reports come to me I shall do myself the honor to address your lordship again concerning it.

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

WILLIAM H. SEWARD.

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