The said renouncement or cession includes all those documents which exclusively refer to said renounced or ceded sovereignty which exist in the archives of the peninsula.  When these documents existing in said archives only in part refer to said sovereignty, copies of said part shall be supplied, provided they be requested.  Similar rules are to be reciprocally observed in favor of Spain with respect to the documents existing in the archives of the before-mentioned islands.  In the above-mentioned renunciation or cession are comprised those rights of the crown of Spain and of its authorities over the archives and official registers, as well administrative as judicial, of said islands which refer to them and to the rights and properties of their inhabitants.  Said archives and registers must be carefully preserved, and all individuals, without exception, shall have the right to obtain, conformably to law, authorized copies of contracts, wills and other documents which form part of notarial protocols or which are kept in administrative and judicial archives, whether the same be in Spain or in the islands above mentioned.

Article IX.—­Spanish subjects, natives of the peninsula, dwelling in the territory whose sovereignty Spain renounces or cedes in the present treaty, may remain in said territory or leave it, maintaining in one or the other case all their rights of property, including the right to sell and dispose of said property or its produces; and, moreover, they shall retain the right to exercise their industry, business or profession, submitting themselves in this respect to the laws which are applicable to other foreigners.  In case they remain in the territory they may preserve their Spanish nationality by making in a registry office, within a year after the interchange of the ratifications of this treaty, a declaration of their intention to preserve said nationality.  Failing this declaration they will be considered as having renounced said nationality and as having adopted that of the territory in which they may reside.  The civil rights and political status of the native inhabitants of the territories hereby ceded to the United States shall be determined by Congress.

Article X.—­The inhabitants of the territories whose sovereignty Spain renounces or cedes shall have assured to them the free exercise of their religion.

Article XI.—­Spaniards residing in the territories whose sovereignty Spain cedes or renounces shall be subject in civil and criminal matters to the tribunals of the country in which they reside, conformably with the common laws which regulate their competence, being enabled to appear before them in the same manner and to employ the same proceedings as the citizens of the country to which the tribunal belongs must observe.
