Mr. McCulloch to any officer of the United States Navy or Army.

The brig Irresistible, a South American privateer, has left this port contrary to law.

The collector of the customs, therefore, according to instructions repeatedly directed to him from the Secretaries of the Navy and of War, requests the assistance of any naval officer or military commander to follow, detain, and send back said brig to this or any other judicial district of the United States.

Respectfully,

JAMES H. McCULLOCH.
