_Anales del Museo Nacional de Historia Natural de Buenos Aires._ Begins 1864, 25 vols., folio and quarto, to 1914. _Anales del Museo de la Plata._ First series 1890-1900, second series from 1907. _Revista del Museo de la Plata._ From 1890-1891, 17 vols. to 1910-1911. All these reviews contain especially articles on the parts of the country which were last explored--Patagonia, Chaco, Misiones. They contain little about the parts that were early colonized, though these are not always the best known. 2. MAPS. The maps published in the eighteenth century (D'Anville's map, 1733, in the _Lettres edifiantes_, 19th collection, Paris, 1734: Bellin's map in vol. ii of the _Histoire du Paraguay_ of the R.P.P.F.X. de Charlevoix, Paris, 1756, 3 vols., etc.) are based upon information collected by the Jesuit missionaries. D'Azara's map (1809) shows a remarkable advance. Important corrections of D'Azara's map are found in Woodbine Parish's map (1838). Brackebusch's two maps are essential documents: _Mapa del interior de la Republica Argentina_, por el Dr. L. Brackebusch, 1:1,000,000 (Gotha, 1835) and _Mapa geologico del interior de la Republica Argentina_, 1:1,000,000 (Gotha, 1890). The results of earlier work have been used in the _Atlas de la Republica Argentina construido y publicado por el Instituto Geografico Argentino_ (Buenos Aires, 1894), which includes a list of its sources. Since that date many maps have been published: maps of the various provinces and surveys drawn up by the railway companies, the Chile Frontier Commission (see Patagonia), the Mines Division (see Natural Regions), and the Ministerio de Obras Publicas (see River Routes). A brief account of the history of Argentine cartography and a list of maps of provinces will be found in Colonel B. Garcia Aparicio, _La carta de la Republica (Anuario del Instituto Geografico Militar_, i, 1912, Buenos Aires, pp. 1-27). The Military Geographical Institute has itself published a large number of maps, either on the basis of fresh surveys or by compiling earlier work, chiefly:-- About thirty sheets on the scale 1:25,000 (Pampean region) since 1904, interesting for studying the relief of the plain. "Governacion de la Pampa," 1:500,000 (Estado Mayor, 3A Division, Buenos Aires, 1909). Three sheets on the scale 1:1,000,000 (Buenos Aires, Concordia, and Corrientes). Buenos Aires, provisional edition 1911 of a map of Argentina on the scale 1:1,000,000, which is to comprise twenty-one sheets. A convenient reference map, though of no scientific value, is the map of the railways, on the scale 1:2,000,000, in three sheets, published in 1910 by the Ministerio de Obras Publicas. 3. STATISTICS. A summary of the chief statistics is published annually in _The Argentine Yearbook_ (from 1902 at Buenos Aires; from 1909 at Buenos Aires and London).
