circumference of the Earth nearly five leagues, in 

 order to have a height proportioned to the courfe 

 of the Ocean, which extends as far as the Line, 

 ninety degrees diftant, that is to fay, two thou- 

 fand, two hundred and fifty leagues, in a fiiraight 

 line. 



If we farther confider, that the courfe of the 

 Ocean does not terminate at the Line, but that 

 when it defcends in Summer from our Pole, it ex- 

 tends beyond the Cape of Good-Hope, as far as 

 to the eaftern extremities of Afia, where it forms 

 the current known by the name of the wefterly 

 Monfoon, which almoft encompaffes the Globe, 

 under the Equator, we fhall be under the neceffity 

 of affigning to the Pole, from which it takes it's 

 departure, an elevation proportioned to the courfe 

 which it is deftined to perform, and of tripling, 

 at leaft, that elevation, in order to give it's waters 

 a fufficient declivity. I put it down, then, at fif- 

 teen leagues : and if to this height we add that of 

 the ices which are there accumulated, the enor- 

 mous pyramids of which over icy mountains, 

 have fometimes an elevation of one-third above 

 the heights which fupport them, we fliall find that 

 the Pole can hardly have lefs than an elevation of 

 the twenty- five leagues above the circumference 

 which Cqfmi affigned to it.
