The President of the French Republic, according to the provisions of the convention, has been selected as arbiter in the case of the General Armstrong, and has signified that he accepts the trust and the high satisfaction he feels in acting as the common friend of two nations with which France is united by sentiments of sincere and lasting amity.

The Turkish Government has expressed its thanks for the kind reception given to the Sultan’s agent, Amin Bey, on the occasion of his recent visit to the United States.  On the 28th of February last a dispatch was addressed by the Secretary of State to Mr. Marsh, the American minister at Constantinople, instructing him to ask of the Turkish Government permission for the Hungarians then imprisoned within the dominions of the Sublime Porte to remove to this country.  On the 3d of March last both Houses of Congress passed a resolution requesting the President to authorize the employment of a public vessel to convey to this country Louis Kossuth and his associates in captivity.

The instruction above referred to was complied with, and the Turkish Government having released Governor Kossuth and his companions from prison, on the 10th of September last they embarked on board of the United States steam frigate Mississippi, which was selected to carry into effect the resolution of Congress.  Governor Kossuth left the Mississippi at Gibraltar for the purpose of making a visit to England, and may shortly be expected in New York.  By communications to the Department of State he has expressed his grateful acknowledgments for the interposition of this Government in behalf of himself and his associates.  This country has been justly regarded as a safe asylum for those whom political events have exiled from their own homes in Europe, and it is recommended to Congress to consider in what manner Governor Kossuth and his companions, brought hither by its authority, shall be received and treated.

It is earnestly to be hoped that the differences which have for some time past been pending between the Government of the French Republic and that of the Sandwich Islands may be peaceably and durably adjusted so as to secure the independence of those islands.  Long before the events which have of late imparted so much importance to the possessions of the United States on the Pacific we acknowledged the independence of the Hawaiian Government.  This Government was first in taking that step, and several of the leading powers of Europe immediately followed.  We were influenced in this measure by the existing and prospective importance of the islands as a place of refuge and refreshment for our vessels engaged in the whale fishery, and by the consideration that they lie in the course of the great trade which must at no distant day be carried on between the western coast of North America and eastern Asia.

We were also influenced by a desire that those islands should not pass under the control of any other great maritime state, but should remain in an independent condition, and so be accessible and useful to the commerce of all nations.  I need not say that the importance of these considerations has been greatly enhanced by the sudden and vast development which the interests of the United States have attained in California and Oregon, and the policy heretofore adopted in regard to those islands will be steadily pursued.
