They confift of air bent down from the higher 
regions of the atmofphere; if this air be from 
the fouth, and brought haftily, it becomes a 
wind of very great velocity, moving perhaps 
fixty miles.an hour, is warm and rainy; if. it

velocity, and colder.” 
, From, this’ theory we may conchide, that: all 
our winds in this country which blow from. the 
north or eaft, or any point between them, con- 
ift of regions of air brought from, the north 
and that all our winds blowing from the fouth 
or weft, or from any point between them, are 
regions of; air from the fouth; and that, in 
places where there are no local circumftances 
which. divert the winds from the courfe they
