The Voyage dans l'Amérique méridionale of Alcide d'Orbigny contains his observations on the Paraná, the province of Corrientes, the Pampa (Parchappe's voyages), and Patagonia (1828). (Historical section, vol. i, Paris, 1835; vol. ii, Paris, 1839-43; vol. iii, third part, geology, Paris, 1842).
Darwin also visited the coast of Patagonia and crossed the Pampa (1833): Narrative of the Surveying Voyage of H.M.S. "Adventure" and "Beagle" ... vol. iii, as Journal and Researches (London, 1839).
Sir Woodbine Parish's work, Buenos Aires and the Provinces of the Rio de la Plata (London, 1838), is remarkably well-informed, and is based upon a thorough study of previous publications and archives.
W. MacKann's Ten Thousand Miles' Ride through the Argentine Republic (London, 1855, 2 vols.) is interesting, and the work of a close observer.
Martin de Moussy, Description géographique et statistique de la Confédération argentine (Paris, 1858, 3 vols. octavo and atlas), is unequal, but full of information.
The work of H. Burmeister, Description physique de la République argentine (Paris, 2 vols., 1876), is of little value, and has been overrated.
Richard Napp, Die Argentinische Republik (Buenos Aires, 1876, I vol. octavo), includes a valuable chapter by P. G. Lorentz on the flora ("Vegetationsverhaeltnisse Argentiniens," pp. 87-149).
The second volume ("Territoire") of the Second recensement de la République argentine (Buenos Aires, 1898) includes a joint geographical study by a number of writers.
