Summer îs five or iix days longer than our Winter. 

 A farther confequence is, that our Pole cannot lofe 

 it's centre of gravity, till the opp'^fite Pole becomes 

 loaded with a weight of ice fuperior to the gravity of 

 our Continent, and of the ices of our Hemifphere ; 

 and this, likewife, is agreeable to fad, for the ices 

 of the South Pole are rnore elevated, and more 

 extenlive than thofe of the northern ; for mariners 

 have not been able to penetrate farther than to 

 the 70th degree of Soudi Latitude, whereas they 

 have advanced no lefs than 82^ North. 



Here we have a glimpfe of the reafons by which 

 Nature was determined to divide this Globe into 

 two Hemifpheres, of which the one fhould con- 

 tain the greateft quantity of dry land, and the 

 other the greatefl quantity of water ; to the end 

 that this movement of the Globe fhould poffefs, 

 at once, confiftency and verfatility. It is farther 

 evident, why the South P;le is placed immediately 

 in the midft of the Seas, far from the vicinity of 

 any land ; that it might be able to load itfelf with 

 a greater mafs of marine evaporations, and that 

 thefe evaporations accumulated into ice around it, 

 might balance the weight of the Continents with 

 which our Hemifphere is furcharged. 



And here 1 lay my account with being oppofed 

 by a very formidable objedion. It is this. If the
