atmofphere ; and, having there acquired a greater 
velocity than the earth’s furface, are frofty

formed into a vertical fpiral eddy, as on the

the velocity of the earth’s furface as they ap-

They confift of retrograde fouth winds; thefe 
continue but a day or two; are preceded by 
fouth-weft wind; and are generally fucceeded 
by north-eaft winds, cloudy or rainy, barometer
