any channel to the courfe of the polar effluxes, 

 from the vaft divergence of America and Afia, we 

 may, however, catch a glance of one, fenfibly form- 

 ed by the projedlion of it's Archipelagoes, which are 

 in correfpondence with the two Continents. By 

 means of this channel it is, that the Sandwich 

 Illands, which are fituated in the northern part of 

 the South Sea, toward the 21ft degree of Latitude, 

 have two tides a day, from the divergent pofition 

 of America and of Afia, though the ftrait, which 

 feparates thefe two Continents, be in the 65th de- 

 gree of North Latitude. Not that thofe iilands 

 and this ftrait of the North are exadly under the 

 fame Meridian ; but the Sandwich iflands are placed 

 on a curve, correfponding to the finuous curve of 

 America, and whofe origin would be at the ftrait 

 of the North. That curve might be prolonged to 

 the moft remote Archipelagoes of the South Sea, 

 which are vifited with two tides a day ; and it 

 would there exprefs the Current formed by the 

 divergent feparation of America and Afia, as has 

 been faid in another place. All iflands are in the 

 midft of currents. On looking, therefore, at the 

 South Pole of the Globe, with a bird's-eye view 

 wc fhould fee a fucceffion of Archipelagoes, dif- 

 perfed in a fpiral line all the way to the Northern 

 Hemifphere, which indicates the Current of the 

 South Sea, juft as the projeélion of the two Conti- 

 nents, on the fide of the North Pole, indicates the 



Current
