To the Senate of the United States:
I transmit to the Senate, for their advice with regard to its ratification, a treaty between the United States and the Mexican Confederation, signed by the plenipotentiaries of the respective Governments on the 10th of July last. It will be seen by its terms that if ratified by both parties the ratifications are to be exchanged at this city on or before the 10th day of next month. the ratification on the part of the Government of Mexico has not yet been received, though it has probably before this been effected. To avoid all unnecessary delay the treaty is now communicated to the Senate, that it may receive all the deliberation which, in their wisdom, it may require, without pressing upon their time at a near approach to the close of their session. Should they advise and consent to its ratification, that measure will still be withheld until the ratification by the Mexican Government shall have been ascertained. A copy of the treaty is likewise transmitted, together with the documents appertaining to the negotiation.
JOHN QUINCY ADAMS.
