On the 26th of March last the United States schooner Lizzie Major was arrested on the high seas by a Spanish frigate, and two passengers taken from it and carried as prisoners to Cuba.  Representations of these facts were made to the Spanish Government as soon as official information of them reached Washington.  The two passengers were set at liberty, and the Spanish Government assured the United States that the captain of the frigate in making the capture had acted without law, that he had been reprimanded for the irregularity of his conduct, and that the Spanish authorities in Cuba would not sanction any act that could violate the rights or treat with disrespect the sovereignty of this nation.

In order to comply with the agreement of the United States as to a mixed commission at Lima for the adjustment of claims, it became necessary to send a commissioner and secretary to Lima in August last.  No appropriation having been made by Congress for this purpose, it is now asked that one be made covering the past and future expenses of the commission.

The good offices of the United States to bring about a peace between Spain and the South American Republics with which she is at war having been accepted by Spain, Peru, and Chile, a congress has been invited to be held in Washington during the present winter.
