US Presidency
1849

It was proper that the amendments to the treaty adopted by the United States should be explained to the Mexican Government, and explanations were made by the Secretary of State in his letter of the 18th of March, 1848, to the Mexican minister for foreign affairs, under my direction. This dispatch was communicated to Congress with my message of the 6th of July last, communicating the treaty of peace, and published by their order. This dispatch was transmitted by our commissioners from the City of Mexico to the Mexican Government, then at Queretaro, on the 17th of April, 1848, and its receipt acknowledged on the 19th of the same month. During the whole time that the treaty, as amended, was before the Congress of Mexico these explanations of the Secretary of State, and these alone, were before them. The President of Mexico, on these explanations, on the 8th day of May, 1848, submitted the amended treaty to the Mexican Congress, and on the 25th of May that Congress approved the treaty as amended, without modification or alteration.
