278 A Voyage to 



wiAout regarding its Longitude, but only the Difference 

 of the Meridian of Lima, tranfporting in like manner all 

 the Coaft to the Weftward, according to the Obfervation 

 of Don Pedro Peralta, one Degree 45 Minutes more to the 

 Weft, than it was laid down in la Connoiffance des Tempt, 

 at Paris , in 171 2. The Sieur Alexander, a Frenchman, 

 Jiving at Lima, who has taken Obfervations apart and 

 with Per alt a, by the Eclipfes of Jupiter 's Satellites, placed 

 it ftill 30 Minutes more to the Weftward, that is, it is 80 

 Degrees 15 Minutes, or 5 Hours 21 Minutes Difference 

 from the Meridian of Paris, according to Monfieur Caf- 

 fini's Tables ; but Father Feuille'e, upon an Obfervation 

 taken by the Sieur Alexander Durand, places it in 79 De- 

 grees, 9 Minutes, and 3 o Seconds, 

 Errors of Thofe who had made ufe of the printed Charts of Peter 

 Charts. Goos,Van Keulen, and Edmund Halle), counted themfelves 

 70, 80, and even above no Leagues within the Land, 

 * according to the laft, which are the worft of them for the 

 South Sea, tho' the neweft and corrected on the Coaft of 

 Brajil by Aftronomical Obfervations. All the French Ships 

 which return from Callao to La Conception, find the fame 

 Errors ; whence it muft be concluded, that it is about five 

 Degrees more to the Eaftward than Lima, and confequently 

 I judged that it muft within a very fmall matter be 75 De- 

 grees 15 Minutes, or 5 Hours 1 Minute of Weftern Diffe- 

 rence from the Meridian of Paris, which amounts to the 3 03 

 Degrees 51 Minutes from Teneriff. This Computation is 

 alfo confirm'd by the Pofition of the Coaft, very well known 

 in many Places, which would beneedlefs and very tedious 

 to particularize •> but in fhort, I found it re&ify'd by the 



Obfer- 



* This Author, for Reafons unknown, feeks all Occafions to cavil at the Perform 

 mance of Mr. Hal ley, in his Chart of the Variations. He might know that that 

 Chart pretends to defcribe the South Sea no otherwife than by borrowing from for- 

 mer Maps, he having no Experience there, as himfelf acknowledges. But if 

 M. FrezierV Sailors could be mijlaken a Degree or two in Latitude, in five Days 

 Sailing, as he owns, p. 275* what hinders but in this five Weeks Voyage, they 

 might err three times as much in Longitude. A farther Anfwer to this, and 

 fome other fuch like Exceptions, [hall folhw at the End of the Book.
