 HEMISPHERE. 



KNOTS AND CHAINS OF THE ANDES IN SOUTH 

 AMERICA. 



Lat. 5J°— 7° 



Knot of the Province of Antioquia in which 

 only the chains of Quindiu and Choco join. 

 The eastern chain approaches by counter-forts 

 towards Honda. 



Lat. 7°— 9° 



Ramification of the knot of the mountains of An- 

 tioquia into four branches : 1st. of Simitarra j 

 2d. of Caceres, Nechi, and Altos de Tolu ; 3d. 

 between the Rio S. Jorge and the Atrato ; 4th. 

 on the west of the Atrato. This last branch, ex- 

 tremely low, appears to be linked at the utmost 

 by an inconsiderable ridge, (seuil,) to the 

 mountainous groupe of the isthmus of Panama. 

 The eastern chain of the Andes of New Grenada, 

 that of Suma Paz, and the Sierra Nevada of 

 Merida, remains separated from the Sierra Ne- 

 vada of Santa Marta, by the plains of Rio Ce- 

 sar j but it joins, by the mountains Barquesi- 

 meto and Nirgua, the Cordillera of the shore 

 of Venezuela, of which the culminant points 

 are the Silla de Caraccas, the Bergantin, the 

 Turimiquiri, and the promontory of Paria.
