begins to forfake the South Pole, and proceeds to^warm the 

 North, the efFufions of the South Pole are ftayed ; thofe-of 

 our Pole begin to flow, and the Currents of the Ocean 

 change in all Latitudes. The general Current of the 

 Seas then takes it's departure from our Pole, and divides, 

 like that of the South, into two branches. The firfi: of 

 thefe branches derives it's fourcesfrom Waigats, Hudfon's- 

 bay, &:c. which then flow, in certain flraits, with the rapi- 

 dity of a fluice, and produce, to the North, tides which 

 come from the North, from the Eaft, and from the Weft, 

 to the great aftonifliment of Linjchotien^ Ellis, and other 

 Navigators, who had been accuflomed to fee them come 

 from the South along the coafts of Europe. 



This Current, formed by the fufion of mofl of the ices 

 pf the North of America, of Europe, and of Afia, which, 

 at that feafon, prefent a circumference of almoft fix thou-, 

 fand leagues, defcends through the Atlantic Ocean, pafles 

 the Line, and finding itfelf confined at the fame Strait of 

 Guinea and Brafil, it forms on it's fides, two lateral coun- 

 ter-currents, which fet in northward, as thofe formed, fix 

 months before, by the Current of the South Pole, fet in 

 foutbward. Thefe counter-currents produce, on the coafts 

 of Europe, the tides which always appear to come dircdly 

 from the South, though they adually come, at that feafon, 

 from the North. 



The branch which produces them advances afterward to 

 the South, doubles the Cape of Good-Hope, takes it's 

 courfe eaft ward, forms, in the Indian Ocean the wefterly 

 monfoon ; and having encompafled the Globe, even to the 

 Soutlv-Sea,-lt proceeds to Cape Horn, re-afcends along the 

 coaft of Brafil, and there produces a current which termi-
