The _Anuario de la Direccion General de Estadistica_, which has appeared since 1880 in one, two or three vols. quarto, gives the figures of trade, immigration, agriculture, railways, navigation, etc. (last volume consulted is for 1914, Buenos Aires, 1915). In the third volume of the _Anuario_ for 1912 will be found a list of the publications of the Direccion de Estadistica. Besides the _Anuario_ the Direccion publishes a bulletin with commercial statistics (last number consulted 181, "El comercio exterior Argentino en los primeros trimestres de 1918 y 1919," Buenos Aires, 1919). _Boletin_ 176 contains a review of Argentine trade from 1910 to 1917. The statistical department of the Ministry of Agriculture, under the direction of E. Lahitte, publishes the _Boletin Mensual de Estadistica Agricola_ (last volume consulted, xxi, 1919). 4. GENERAL DESCRIPTIONS.[148] [148] Besides the publications of the Jesuits, which can easily be consulted, a fairly large number of texts bearing upon the history of colonization have been published or re-published in the nineteenth and the twentieth century. See especially: _Relaciones Geograpicas de Indias_ (vol. i, 1881; vol. ii, 1885, Madrid). _Anales de la Biblioteca National, Buenos Aires, Publicacion de documentos relativos al Rio de la Plata_ (from 1900). Publications of the _Junta de Historia y Numismatica Americana_ (Buenos Aires, 7 vols., octavo, from 1905 to 1915). Valuable notes on some of the most important historical documents will be found in E. Boman, _Antiquites de la region andine_ (see North-West Argentina). The most curious collection of all for the geographer is: Pedro de Angelis, _Coleccion de obras y documentos relativos a la historia antigua y moderna de las provincias del Rio de la Plata_ (Buenos Aires, 1837, 6 vols, octavo, containing many itineraries, journals of expeditions, etc., together with notes by D'Azara). The scientific study of this part of South America may be traced back as far as D'Azara. His observations are collected in Don Felix de Azara, _Voyages dans l'Amerique meridionale_, published by Walckenaer (Paris, 1809, 4 vols. in 12^{mo} and atlas) and _Descripcion e historia del Paraguay y del Rio de la Plata_, published by D. Agustin de Azara (Madrid, 1847, 2 vols. octavo). The _Voyage dans l'Amerique meridionale_ of Alcide d'Orbigny contains his observations on the Parana, 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).
