ADTERTISEMENT. ixiX 



Bifcay, arrived on the coafts of Normandy, is a 

 new proof of the exiilence and of the velocity of 

 the alternate and half-yearly Current of the Atlan- 

 tic Ocean, hitherto unknown, which I have affimi- 

 lated to that of the Indian Ocean, and afcribed to 

 the fame caufe. 



It may be afcertained, by pricking the chart, 

 that the place where the Englifliman's bottle was 

 toffed into the Sea, is more than 80 leagues from 

 the Continent, and precifely in the direftionof the 

 middle of the opening of the Britilh Channel, 

 through which paffes one arm of the general Cur- 

 rent of the Atlantic, which carried, in fummer, 

 the wrecks of the battle of OAend as far as the 

 Azores. Now, this Current was likewife bearing 

 fouihward, when the Englifh traveller committed 

 to it a letter for his friends in the North, for it was 

 the I 7th of Auguft, that is, in the fummer of our 

 Pole, when the fufion of it's ices is flowing fouth- 

 ward. This bottle, therefore, failed toward the 

 Azores» and, undoubtedly, far beyond them, dur- 

 ing the remainder of the month of Auguft, and the 

 whole month of September, till the equinodial re- 

 volution, which fends backward the courfe of the 

 Atlantic, by the effufionr, of the South Pole, began 

 to -waft it again to the North.
