Winds as much Northerly and Eafterly, and as ftrong j

more than ordinary fevere Weather. 
But as to mifty, cloudy, dark Weather, 
in<^enious Author reckons among his principal Caules, i 
am lo far from thinking it a Caufe, that I rather take it 
to be the reafon we have not more frequent fevere Frolls, . 
at kaft in Our Ifland-places, furrounded by the warm Va- 
pours of the Sc^i. Clouds and Vapours do indeed inter-
