The icy and fandy Zones are found, in a diffe-

 South, whereas thofe of the Old Continent are di- 

 reded, conformably to the length wife direction of 

 the Indian Ocean, from Weft to Eaft. 



It is very remarkable, that the influence of icy 

 mountains extends farther over the Ocean than 

 over the Land. We have feen thofe of the two 

 Poles take the dire6lion of the channel of the At-
