Surville, mingling old hypotheses with accurate 

 ideas; would reproduce on their maps the Mar 

 Dorado, or Mar Blanco. Thus, notwithstanding- 

 the numerous proofs, which I have furnished 

 since my return from America, of the non- 

 existence of an inland sea, the origin of the 

 Oroonoko, a map has been published in my 

 name* on which the Laguna Parima figures 

 anew. 



From the whole of these statements it follows, 

 1st, that the Laguna Rupunuwini, or Parima of 

 the voyage of Raleigh and of the maps of Hon- 

 diuSj is an imaginary lake, formed by the lake 

 Amucuf-, and the tributary streams of the Ura- 

 ricuera, which often overflow their banks ; 2dly 5 

 that the Laguna Parime of Surville's map is the 

 lake Amucu, which gives rise to the Rio Pirara, 



added in 1779, make mention of the Laguna Parima {Lib. 1, 

 c. 10, p. 60), it is only to denote the lake, from which the 

 Pirara issues. (Gili, vol. i, p. 325.) 



* Carte de VAmtrique, dressee sur les Observations de M. de 

 Humboldt, par Fried. (Vienna, 1818.) Notwithstanding my 

 observation of the latitude at the rock of Culimacari, which 

 gives jl° 53 1 42" for San Carlos del Rio Negro, the equator 

 is made to pass on this map, not between San Felipe and the 

 mouth of the Guape, but at the confluence of the Uteta or 

 Xie. This error is also found on the maps of Laurie and 

 Whittle (1809), and on that of Cary (1817). See above, p. 

 413. 



t This is the lake Amaca of Surville and La Cruz. By 

 a singular mistake, the name of this lake is transformed into 

 a village on Arrowsmith's map.
