of Air fhould be carried, for fo long a Time, and 
with fo great Violence, as we have often felt, from 
a warmer to a colder, from a rarer to a denfer, from 
a lighter to a heavier Quarter ? To the North-eaft of 
us lies the Continent of North-Europe , great Part of 
which is, in the Winter, deprived of the Sun's Heat, 
and confequently very cold ; on the other Side, to 
the South-weft, lies the vaft Atlantic Ocean. We 
find by Experience, that the Sea-fhore is warmer than 
the Inland ; that the Sea is warmer than the Shore ; 
and that the Ocean is ftill warmer than the Sea. 
Befides, the more you go from hence towards the 
South, the nearer you go to the Sun ; and the more 
North, the farther from it : This muft make the 
South- weftern Ocean much warmer than the Con- 
tinent, that lies at an equal Diftance, on the oppofite 
Points From this very warm Place, the Wind blows 
to a Place much colder ; and yet there muft be a 
natural Caufe of all this apparent Contradi&ion to 
the Laws of Nature : Whether we can find it out or 
not, I fhali attempt it at well as I can. 
It will be in vain to feek for the Caufe of this 
Wind in this Ocean itfelf, or in the Air over it, 
influenced only by the Sun, and the Surface of the 
Sea. But there may be Tornados in thofe Seas : Our 
Seamen often meet them between the Tropics, feK 
dom, as I am told, in the Ocean I am now fpeaking 
of, which is to the North of the Northern Tropic. 
But were they more frequent and violent than they 
really are, yet they are not lading, and therefore 
cannot produce a long fteady Courfe of South-weft, 
Winds with us.
