 the Caqueta, to the great regret of la Conda-

 the Rio Negro, entirely independant rivers ; 

 and, as if to banish all hope of communication 

 between the Oroonoko and the Rio Negro, 

 figured a lofty chain of mountains between the 

 two rivers. Father Fritz J had before followed 

 the same system, which was believed to be the 

 most probable in the time of Hondius.

 has thrown so much light on different parts of 

 America, has embroiled all that is connected 

 with the courses of the Caqueta, the Oroonoko, 

 and the Rio Negro. This illustrious traveller 

 has well observed, it is true, that the Caqueta 

 (of Mocoa) was the river, which, in the Ama- 

 zon, bears the name of Jupura ; but he not only 

 adopted the hypothesis of Sanson, he even trip-

 Jupura and the Rio Paragua ; and by a third 

 the Rio Paragua is subdivided into two rivers,
