 ftorm. 



The effufions of the polar ices, in like manner, 

 cool the feas of the South ; and the polar winds 

 frequently blow on the hotteft parts of their 

 mores. Nature has, farther, placed in the very 

 heart of the Torrid Zone, and in it's vicinity, 

 chains of icy mountains, which accelerate, and re- 

 double the effects of the polar winds, efpecially 

 along the feas, where fermentation was moll to be 

 dreaded, from the alluvions of the bodies of ani-

 Mount Taurus, eternally covered with fnow, com-

 and, coafting the Mediterranean, pâlies on into 

 Afia, where it extends long arms, this way and
