Progress of Geography in 1836-7.

gable passage exists from the town of Pozuzu on the Pachitea, within 

 300 miles of Lima, by the rivers Ucay all afid'the Amazons to the Atlan- 

 tic Ocean ; a fact which may prove of incalculable importance to th© 

 rising states of Bolivia and Peru. 



Perw.—General Miller has accomplished a journey of 150 miles both 

 to the northward and eastward of Cuzco, and has thrown much light on 

 the hydrography of that part of the country in tracing the course of a 

 river supposed to be one of the largest tributaries of the great river 

 Purus, if not the river itself. 



Rio de la Plata. — An important addition to our knowledge of this 

 country has just been made by Don Pedro de Angelis, at Buenos Ayres 

 in a ' Coleccion du Documentos,^ &c., relative to the History of the Rio 

 de la Plata; being a collection of original documents, some of especial 

 value to the topographer, as, for instance, the journal of Don Luisde 

 la Cruz, who in 1806 crossed the Andes and the Pampas, to establish a 

 road from Concepcion in Chile to Buenos Ayres. The work is enrich» 

 ed with valuable notes by the editor ; and it is highly gratifying to find 

 the members of a new republic profiting by the first moment of politi- 

 cal tranquillity to collect and publish the original papers connected 

 with the history of their country. 



Another original document on this part of South America, namely? 

 the * Diary of Don Basilio Villarino,' who explored the Rio Negro, in 

 1782, from the Atlantic to the foot of the Andes, has been communi- 

 cated to the Geographical Society by Sir Woodbine Parish. 



M. Alcide d'Orbigny's beautiful work on the Natural History of the 

 Bepublic of La Plata, and the Banda Oriental, is publishing at Paris, 

 and has reached its twelfth number ; and Dr. Rengger's * Reise nach 

 Paraguay,' just published at Aarau, gives us the results of eight years* 

 residence in that country. 



Patagonia. — Proceeding southwards along the shores of this vast 

 continent, we now come to the account of an expedition just completed, 

 which has brought home a greater mass of accurate geographical infor- 

 mation than any expedition since the voyages of Cook and of Flinders; 

 namely, the survey of the coasts of Patagonia, Terra del Fuego, Chile, 

 and Peru, by Captain Fitz Roy, R. N. in His Majesty's Ship Beagle. 

 Beginning with the southern bank of the wide Rio de la Plaeta, every 

 mile of the coast thence to Cape Horn was closely surveyed and laid 

 down on a large scale; each harbour and anchorage was planned ; thirty
