disputes respecting the French and Portuguese Guy anas. By 

 drawing a line from north to south, by the mouth of the 



from the source of the Maroni, or rather from one of its 

 branches, the Rio Araoua, near the village of the Aramichaun 

 Indians. The Portuguese being desirous of tracing the limits 

 between the Oyapok and theAraguari (Araouari), caused the 

 latitude of the source of the latter river to be carefully exa- 

 mined by Colonel de Souza ; it was found to be further north 

 than the mouth, which has placed the frontier in the parallel of 

 Calsoene. The name of the Rio de Vicente Pinion, become ce- 

 lebrated in the annals of diplomatic disputes, has disappeared 

 on the new maps. According to an ancient manuscript Por- 

 tuguese map in my possession, and where the coast is marked 

 between San Jose de Macapa and the Oyapok, the Pincon 

 must be identical with the Calsoene. I suspect that the un- 

 intelligible terms of the 8th article of the treaty of Utrecht 

 (" the line of the river Japoc or Vincente Pingon, which ought 

 to cover the possessions of the cape and of the north") are 

 founded on the denomination of Cape North, sometimes given 

 to Cape Orange. (See Laet Nov. Orb. 1633, p. 636). M. de 

 la Condamine, whose sagacity nothing escapes, has already 

 said, in the Relation de sen Voyage ci VAmassone, p. 199, " the 

 Portuguese have their reasons for confounding the bay (?) 

 of Vincent Pincon, near the western mouth of the Rio Ara- 

 wari (Araguari), lat 2° 2', with the river Oyapok, 4° 15' lat. 

 The peace of Utrecht makes it one river." This latitude 

 2° 2' would bring the imaginary river of Pinion near the 

 Majacari and the Calsoene, and remove it nearly one degree 

 from the Araguari, which is in lat. I 9 15'. Mr. Arrowsmith, 

 whose map furnishes excellent materials for tracing the 

 mouth of the Amazon, places the Rio de Vicente Pincon on 

 the south of Majacare, where the Matario loses itself in a 

 bay, opposite which the small isle Tururi is situated, lat. 

 1° 50'. As the Araguari, communicating with the Matario P
