the forests of the coasts there, and returned on foot, along 

 the shore, back to Bahia. A second important journey led 

 them in a north-westerly direction, through the province of 

 Bahia by Joazeiro, across the beautiful river of S. Francis- 

 co, resembling the Rhine, to the hilly pastures of the pro- 

 vince of Piauhy, which they completely crossed in order to 

 reach S. Luiz, the capital of the province of Maranham. 

 Then they took ship to Para, and from that town ascended 

 the Amazon River and the Salimoens to Ega, where they 

 separated for a time, Dr Von Spix following the course of the 

 Salimoens to the boundary of Brazil, while Dr Von Martius, 

 accompanied by Colonel Zany, went up the Yupura as far as 

 the falls of Arara-Coara on the borders of Popayan. Meet- 

 ing again at the Barra do Rio Negro, they descended the 

 Amazons and visited the lower territory of the Madeira 

 river. 



From Para these indefatigable Naturalists returned to 

 Munich by way of Lisbon, at the end of the year 1821; and 

 the number of species calculated to be brought home by Von 

 Martius, is 7,500. Already the public has been favoured
