(that of Hondius, Sanson, and Coronelli) was 

 also surrounded by mountains, and gave birth 

 to no river,, while the lake Parima of La Cruz 

 and the modern geographers communicates 

 with the Upper Oroonoko, as the Cassipa with 

 the Lower Oroonoko *. 



I have stated the origin of the fable of the lake 

 Cassipa, and the influence it has had on the 

 opinion, that the lake Parima is the source of 

 the Oroonoko. Let us now examine what re- 

 lates to this latter basin, this pretended interior 

 sea, called Rupunuwini by the geographers of the 

 sixteenth century. In the latitude of four degrees 

 or four degrees and a half, (in which direction 

 unfortunately, south of Santo Thome del Angos-

 right bank of the Oroonoko, to Esmeralda, and thence through 

 the confluence of the Rio Branco with the Rio Negro, along 

 the latter river as far as "Vistoza (on the left bank of the 

 Amazon), and to the sources of the Oyapok, we shall have
