ANNOTATIONS AND ADDITIONS. 107 



most northern mountains, called the group of the Parime, 

 are opposite to the Andes of Cundinamarca which project 

 far to the east, and assume in the 66th and 68th degrees of 

 longitude the form of high mountains, connected by the 

 narrow ridge of Pacaraima with the granite hills of French 

 Guiana. On the map of Columbia constructed by me from 

 my own astronomical observations, this connection is clearly 

 marked. The Caribs, who penetrated from the missions of 

 the Caroni to the plains of the Rio Branco, and as far as the 

 Brazilian boundary, crossed in the journey the ridges of 

 Pacaraima and Quimiropaca. The second mountain mass, 

 which divides the valley of the Amazons from the Eiver 

 Plate, is the Brazilian group. In the province of Chiquitos 

 (west of the Parecis range of hills), it approaches the pro- 

 montory of Santa Cruz de la Sierra. As neither the 

 group of the Parime which causes the great cataracts 

 of the Orinoco, nor the Brazilian group of mountains, are 

 absolutely connected with the Andes, the plains of Vene- 

 zuela have a direct connection with those of Patagonia.

(is) p . s. "Troops of dogs." 



European dogs have become wild in the grassy plains or 

 Pampas of Buenos Ayres. They live in society, and in 

 hollows in which they hide their young. If the society 

 becomes too numerous, some families detach themselves and 

 form new colonies. The European dog, which has become 

 wild, barks as loud as the original American hairy race.
