my power here to infert the relations which moun- 

 tains themfelves have with plants, according to my 

 original intention. All that I can, at prefent, fay

 being the productions of a centrifugal force, or of 

 fire, or of earthquakes, or of water- cou rfes, I know 

 of, at leaft, ten different fpecies, each of which has 

 a configuration the mod perfectly adapted for 

 keeping up, in every particular Latitude, the har-

 of them has, moreover, vegetables and quadrupeds 

 peculiar to itfelf, and which are not elfewhere to 

 be found : -this proves to a demonstration, that 

 they are not the work of chance. Finally, among 

 that inconceivable number of mountains which 

 cover the greatest part of the five Zones, and 

 efpecially the Torrid and the Icy Zones, there is 

 bat one (ingle fpecies, the lead considerable of ali, 

 which prefents to the water-courfes projecting and 

 retreating angles in correfpondence. This, how- 

 ever, is no more their work than the bafon of the 

 feas is itfelf the work of the Ocean. But this in-

Let us now proceed to difplay the harmonies of 

 aquatic plants.
