we see that water, by its coolness, is enabled to assimilate to itself 

 a large quantity of moisture nightly by condensation ; and that the 

 air, when loaded with fogs and vapours, and even with copious dews, 

 can alone advance a considerable and never-failing resource. 

 Persons that are much abroad, and travel early and late, such as 

 shepherds, fishermen, &c., can tell what prodigious fogs prevail in 

 the night on elevated downs, even in the hottest parts of summer ; 

 and how much the surfaces of things are drenched by those 

 swimming vapours, though, to the senses, all the while, little 

 moisture seems to fall.
