278 NATURAL HISTORY 



northern side, and the breath thereof be carried directly 

 upward, and it find a cold cloud on the west side, which 

 turns it off the contrary way, there will blow a north-east 

 wind. 



14. Monition. Nurseries of winds in sea and land are 

 constant, so that the spring and beginning of them may 

 be the better perceived ; but the nurseries of winds in the 

 clouds are moveable, so that in one place there is matter 

 furnished for the winds, and they are formed in another, 

 which makes the direction of motion in winds to be more 

 confused and uncertain. 



Those things we have produced for example s sake, the 

 like are after the like manner; and hitherto of the direction 

 of the motion of winds : now we must see concerning the 

 longitude, and as it were the itinerary or journey of the 

 winds, though it may seem we have already inquired of 

 this under the notion of the latitude of winds ; for latitude 

 may by unlearned men also be taken for longitude, if winds 

 take up more space laterally than they go forward in lon 

 gitude. 



14. If it be true that Columbus could upon the coasts of 

 Portugal judge of the continent of America by the constant 

 winds from the west, truly the winds can travel a long 

 journey. 



15. If it be true that the dissolution of snows about the 

 frozen seas and Scandia do excite and raise northerly winds 

 in Italy and Greece, &c. in the dogdays, surely these are 

 long journeys. 



16. It hath not. yet been observed how much sooner a 

 storm does arrive, according to the way it comes (as for 

 example, if it be an eastern wind), how much sooner it 

 comes from the east, and how much later from the west. 

 And so much concerning the motion of winds in their pro 

 gression or going forward : now we must see concerning 

 the undulation or swelling of winds. 



17. The undulation or swelling of winds is done in a few 

 moments, so that a wind will (though it be strong) rise 

 and fall by turns, at the least a hundred times in an hour ; 

 whereby it appears that the violence of winds is unequal ; 

 for neither rivers, though swift, nor currents in the sea, 

 though strong, do rise in waves, unless the blowing of wind 

 be joined thereunto, neither hath the swelling of winds any 

 equality in itself; for like unto the pulse of one s hand, 

 sometimes it beats, and sometimes it intermits. 



18. The undulation or swelling of the air differs from the
