Since the date of my message of January 17th. a letter of the 26th. of November has been recieved from the Minister Plenipotentiary of the US. at London, covering one from the Secretary for foreign affairs of that government, which, being on the subject of that message, is now transmitted for the information of Congress although nothing forbids the substance of these letters from being communicated without reserve, yet so many ill effects proceed from the publication of correspondences between ministers remaining still in office, that I cannot but recommend that these letters be not permitted to be formally published.
