Thefe two alternate divergent effufions of the Cur- 

 rents of the South Pole, if I am not midaken, is 

 the very circumftance that renders thefe two Capes, 

 which receive their firft impulfion, fo tempefluous, 

 and the doubling of them fo difficult, during the 

 fummer of that Pole, to veflels going out of the 

 Atlantic Ocean ; for then they meet in the teeth 

 the Currents which are defcending from the South 

 Pole. For this reafon it is, that they find it ex- 

 tremely difficult to double the Cape of Good- 

 Hope, during the months of November, Decem- 

 ber, January, February, and March, on Voyages 

 to India, and that, on the contrary, they pafs it with 

 eafe in our fummer months, becaufe they are then 

 aflifted by the Currents of the North Pole, which 

 waft them out of the Atlantic. They experience 

 the contrary of this on their return from India, 

 during our winter months. 



I am induced, from thefe confiderations, to be- 

 lieve that veffels on their way to the South Sea, 

 would encounter fewer obflacles in doubling Cape 

 Horn, during it's winter than during it's fummer; 

 for they would not be then driven back into the 

 Atlantic by the Currents of the South Pole, and 

 they would be affifled, on the contrary, in getting 

 out of it, by thofe of the North Pole. I could 

 fupport this conjeflure by the experience of many 

 Navigators. That of Admiral An/on will perhaps
