Therefore, to ulc our bcft indeavours to content him ; let us 

 rcfleA upon th difpofition of parw of this habitable globe, 

 whereof we are tenants for lives. And we fliall find that the fun 

 by his ccmftantcaurfe under the zodiaekibcatcth a great part of 

 it unmeafurably more then he doth the icfi.Andconfequently, 

 that this zodiaok being in the middert jretween tw^a-s it wcrt) 

 ends, which we call the Poles , thefe poles rauft nccflfarily be 

 extremely cold , in refpeft of the torrid zone ; for fo we call 

 that part of the earth which lieth under the zodi'ack. 



Now looking into the confluence of this ; we find thai the 

 funne, or the funnes heat which refleeth from the earth in the 

 torrid zone, muft rarifie the aire extremely, and according to 

 the nature of all heat and fire, mull needs carry away from 

 thence, many parts of the aire and of the earth flicking to due 

 heat, in fuch fort as we have formerly declared. 



Whence icfolloweth, that other aire muft neceflarily come 

 from the regions towards both the polei , to fupply what is car- 

 ried away from the middle, as is the courfe in other fires, and 

 as we have explicated above : efpccially confidering, that the 

 aire which comcth from the polewards, is hearier then the aire
