4. General Descriptions.[148]
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'Amérique méridionale, published by Walckenaër (Paris, 1809, 4 vols. in 12mo and atlas) and Descripción e historia del Paraguay y del Rio de la Plata, published by D. Agustin de Azara (Madrid, 1847, 2 vols. octavo).
