I transmit a copy of a letter to this Department, signed by the master, the mate, and the passengers of the brig Paragon, of Philadelphia, complaining of an insult to the flag of the United States, committed by the Mexican public armed schooner Tampico, which is represented to have causelessly fired into and detained the Paragon, on her voyage from New York to Vera Cruz.

You will request of the Mexican Government an inquiry into the circumstances of this case, and, if they should prove to have been accurately stated, such redress will be expected as their nature demands.
