ward from this Coaft,. the Variation diminifhes. 

 From thefe two it is a Legitimate Corollary : That 

 Somewhere between Europe, and the North part of A- 

 merica, there ought to he an Eaflerly Variation, or at 

 leaft no Weflerly. And fo I conjecture it is about 

 the Eaftermoft of the Tercera IJIands. 



Thirdly, That on the Coaft of Brafile there is 

 Eaft Variation, which increafes very notably as 

 you go to the Southward, fo as to be ix Degrees 

 at Cape Frio, and over againft the River of Plate 

 10 i Degrees : And from thence Sailing South- 

 westerly to the Strarts of Magellan it decreafes 17 

 Degrees, and at the Weft Entrance but 14 De- 

 grees. 



Fourthly, That at the Eaftward of Brafile, pro- 

 perly fo calFd, this Eafterly Variation decreafes, fo 

 as to be very little at St. Helena and Afcenfiov, and 

 to be quite gone, and the Compafs Point true about 

 18 Degrees of Longitude Weft from the Cape of 

 Good' hope. 



Fifthly, That to the Eaftward of the afore- 

 faid Places a Weftward Variation begins, which 

 Reigns in .the whole Indian Sea, and arifes to 

 no lefs than Eighteen Degrees under the Equa- 

 tor it felf, about the Meridian of the Northern 

 part of Hadagafcar ; and near the fame Meri« 

 dian, but in 39 Degrees South Latitude it is 

 found full 27 k Degrees : From thence Eafter- 

 ly. the Weft Variation decreafes, fo as to be lit- 

 tle more than eight Degrees at Cape Comorin, 

 and than three Degrees upon the Coaft of Ja- 

 va ; and to be quite extinct about the Molucca 

 IJIands, as alfo a little to the Weftwards of Van
