Mr. Brown to Mr. Seward.

Sir: I have the honor to enclose to the department translation of a commucation received from the Sublime Porte, making known to foreign governments a new flag which has been adopted for Ottoman merchant vessels in place of the old one, hereafter to be used by ships-of-war only.

With much respect, your obedient servant,

JOHN P. BROWN.

Hon. William H. Seward, Secretary of State, United States of America.
