FOOTNOTES:
[1] Amongst other documents which I obtained through the kindness of the government were some large topographical maps of the province of Buenos Ayres, drawn expressly for me by desire of General Rosas, the present governor, comprising all the data respecting that province, collected by the topographical department up to the year 1834.
[2] A re-calculation by M. Oltmanns, of some of the observations of the Boundary Commissioners, has slightly altered a few of their positions: his corrections will be found in the volume for 1830, of the Memoirs of the Academy of Sciences of Berlin.
[3] Noticias Historicas y Descriptivas sobre el gran pais del Chaco y Rio Vermejo, por José Arenales.—Buenos Aires, 1833, 8vo.
[4] Collección de Obras y Documentos relativos à la Historia antigua y moderna de las Provincias del Rio de la Plata, ilustrados con Notas y Disertaciones, por Pedro de Angelis.—Buenos Aires, 1836, folio. The completion of this work has been suspended for want of paper to go on with, owing to the French blockade of Buenos Ayres, since March, 1838.
[5] For the convenience of those who may desire to have it separately, the map may be had from Mr. Arrowsmith without the book.
