 Clarke : this, he says, he scarce ever knew to 

 fail ; at least when the wind was in any of the 

 easterly points: but Mr. Derham has observed 

 the rule to hold good, be the wind where it will. 

 And the cause is obvious : The atmosphere is 

 replete with vapours, which, though sulhcient 

 to reflect and intercept the sun's rays from us, 

 yet want density to descend; and while the va- 

 pours continue in the same state, the weather 

 will do so o,
