XÏvi EXPLANATION Ot THE PLATES. 



cfFe£l, from the prelTure, or the attradion of the Sun and 

 of the Moon between the Tropics, as thefe two Luminaries 

 never tranfcend their bounds, and always proceed in one 

 direftion, from Eafl: to Weft : but here is the folution. 

 When this Current of Brafil runs to the South in our 

 Winter, it is the general counter-current of the South Pole, 

 which is then fetting in to the North ; and when this Bra- 

 rdian Current runs to the North in our Summer, it is the 

 extremity of this fame general Current, wliich returns by 

 Cape Horn. 



The fame thing does not take place refpeding the Cur- 

 lent in the Gulf of Guinea, which is oppofite, and which 

 runs always to the Eaft, though it be in precifely the fame 

 Ctuation : for, in our Winter, this Current in the Gulf of 

 Guinea, is the extremity of the general Current of the 

 South Pole, which returns by the Cape of Good-Hope, and 

 which, at that feafon, fets in to the North, along the coafts 

 of Africa, from the thirtieth degree of South Latitude, as 

 far as to the folirth degree of the fame Latitude, according 

 to the teftimony of Dampicr. But this extremity of the 

 general Current which fets in to the North, and which 

 then takes it's departure from the fourth degree South, to 

 join the general Current, does not enter into the Gulf 

 of Guinea, becaufe of the prodigious retreat of that Gulf; 

 fo that, in this part only, the Sea flows always to the Eafl, 

 conformably to the obfervation of all African Navigators.
