OF WINDS. 267 



tion or winding do agitate and tumble it, which is done by 

 extrinsical causes, and the posture of the adjoining bodies. 



1. In places where there are hills which are not very 

 high, bordering upon valleys, and beyond them again higher 

 hills, there is a greater agitation of the air, and sense of 

 winds, than there is in mountainous or plain places. 



2. In cities, if there be any place somewhat broader 

 than ordinary and narrow goings out, as portals or porches, 

 and cross streets, winds and fresh gales are there to be 

 perceived. 



3. In houses cool rooms are made by winds, or happen 

 to be so where the air bloweth through, and comes in on 

 the one side and goeth out at the other. But much more 

 if the air comes in several ways and meets in the corners, 

 and hath one common passage from thence : the vaulting 

 likewise and roundness doth contribute much to coolness, 

 because the air, being moved, is beaten back in every line. 

 Also the winding of porches is better than if they were 

 built straight out. For a direct blast, though it be not shut 

 up, but hath a free egress, doth not make the air so une 

 qual and voluminous, and waving, as the meeting at angles 

 and hollow places, and windings round, and the like. 



4. After great tempests at sea an accidental wind con 

 tinues for a time, after the original is laid, which wind is 

 made by the collision and percussion of the air, through 

 the curling of the waves. 



5. In gardens commonly there is a repercussion of wind, 

 from the walls and banks, so that one would imagine the 

 wind to come the contrary way from that whence it really 

 comes. 



6. If hills inclose a country on the one side, and the wind 

 blows for some space of time from the plain against the 

 hill, by the very repercussion of the hill, either the wind is 

 turned into rain, if it be a moist wind, or into a contrary 

 wind, which will last but a little while. 



7. In the turnings of promontory, mariners do often find 

 changes and alterations of winds. 



Extraordinary Winds and sudden Blasts. 



To the tenth article. Connexion. 



Some men discourse of extraordinary winds, and derive 

 the causes of them ; of clouds breaking, or storms, vortice, 

 typhone, prestere; or, in English, whirlwinds. But they 

 do not relate the thing itself, which must be taken out of 

 chronicles and several histories. 



1. Sudden blasts never come in clear weather, but always
