ANNOTATIONS AND ADDITIONS. 195 



versing the missions on the Piritu and the Carom, he died on the 

 22d of February, 1756, at the mission of Santa Eulalia de Muru- 

 curi, a little to the south of the confluence of the Orinoco and the 

 Caroni. The documents of which Bauza speaks are the same as 

 those on which the great map of De la Cruz Olmedilla is based. 

 They constitute the type of all the maps which appeared in England, 

 France, and Germany, up to the close of the last century; and they 

 also served for the two maps drawn in 1756 by Peter Caulin, the 

 historian of Solano's expedition, and by an unskilful compiler, M. 

 de Surville, Keeper of the Archives of the Secretary of State's office 

 at Madrid. The discordance between these maps shows the little 

 dependence which can be placed on the surveys of the expedition; 

 besides which, Caulin's acute remarks lead us to perceive the cir- 

 cumstances which gave occasion to the fiction of the Lake Parime; 

 and Surville' s map, which accompanies his work, not only restores 

 this lake under the name of the White Sea and of the Mar Dorado, 

 but also adds another lake, from which, partly through lateral out- 

 lets, the Orinoco, the Siapa, and the Ocamo issue. I was able to 

 satisfy myself on the spot of the fact, well known in the missions, 

 that Don Jose' Solano went indeed beyond the cataracts of Atures 

 and Maypures, but not beyond the confluence of the Gruaviare and 

 the Orinoco, in lat. 4 3' and long. 68 9'; that the instruments 

 of the Boundary Expedition were not carried either to the Isthmus 

 of the Pimichin and the Rio Negro, or to the Cassiquiare; and that 

 even on the Upper Orinoco they were not taken above the mouth of 

 the Atabapo. This extensive country, in which previous to my 

 journey no exact observations had been attempted, had been tra- 

 versed since the time of Solano only by a few soldiers sent in search 

 of discoveries; and Don Apolinario de la Fuente (whose journals I 

 obtained from the archives of the province of Quiros) had collected, 

 without critical discrimination, from the lying tales told by Indians, 

 whatever could flatter the credulity of the governor Centurion. No 

 member of the expedition had seen any lake, and Don Apolinario had 

 not advanced farther than the Cerro Yumariquin and the Grehette. 



Having now established throughout the extensive district^ to 

 which it is desired to direct the inquiring zeal of travellers, a divid- 

 ing line bounding the basin of the Bio Branco, it still remains to
