Under these circumstances I submit to the Senate, for their consideration, the amendment to the convention thus proposed by the Congress of Peru, with a view to its ratification. It would have been more satisfactory to have submitted the act itself of the Peruvian Congress, but, on account of the great distance, if I should wait until its arrival another year might be consumed, whilst the American claimants have already been too long delayed in receiving the money justly due to them. Several of the largest of these claimants would, I am informed, be satisfied with the modification of the convention adopted by the Peruvian Congress. A difficulty may arise in regard to the form of any proceeding which the Senate might think proper to adopt, from the fact that the original convention approved by them was sent to Peru and was exchanged for the other original, ratified by General Vivanco, which is now in the Department of State. In order to obviate this difficulty as far as may be in my power, I transmit a copy of the convention, under the seal of the United States, on which the Senate might found any action they may deem advisable. I would suggest that should the Senate advise the adoption of the amendment proposed by the Peruvian Congress the time for exchanging the ratifications of the amended convention ought to be extended for a considerable period, so as to provide against all accidents in its transmission to Lima. JAMES K. POLK. WASHINGTON, _May 27, 1846_. _To the House of Representatives_: In compliance with the request contained in the resolution of the House of Representatives of this date, I transmit copies of all the official dispatches which have been received from General Taylor, commanding the army of occupation on the Rio Grande, relating to the battles[8] of the 8th and 9th instant. JAMES K. POLK. [Footnote 8: Palo Alto and Resaca de la Palma.] WASHINGTON, _May 28, 1846_. _To the Senate and House of Representatives_: I transmit a copy of a note, under date the 26th instant, from the envoy extraordinary and minister plenipotentiary of Her Britannic Majesty to the Secretary of State, communicating a dispatch, under date of the 4th instant, received by him from Her Majesty's principal secretary of state for foreign affairs. From these it will be seen that the claims of the two Governments upon each other for a return of duties which had been levied in violation of the commercial convention of 1815 have been finally and satisfactorily adjusted. In making this communication I deem it proper to express my satisfaction at the prompt manner in which the British Government has acceded to the suggestion of the Secretary of State for the speedy termination of this affair. JAMES K. POLK. WASHINGTON, _June 1, 1846_. _To the Senate of the United States_:
