Hours, or half a Day under the Pole, which 

 fpace Q H H £, is vifibly greater than the other 

 Area H by as much as the Area HG ^ 



is greater than the Area ©5 which, that it 

 is fo, is vifible to fight, by a great excels ; and 

 fb much in proportion does the Heat of the 

 X4 Hours Sun-fliine under the Pole, exceed that 

 of the i i Hours under the Equinoctial : Whence* 

 Ceteris paribus, it is reafonable to conclude, that 

 were the Sun perpetually under the Tropick* 

 the Pole would be at leaft as wafm, as k is now 

 under the Line it felf. 



But whereas the Nature of Heat is to remain 

 in the Subject, after the Caufe that heated is re- 

 moved, and particularly in the Air ; under the 

 Equinoctial, the i ^ Hours abfence of the Sun 

 does very little flill the Motion impreffed by 

 the paft Action of his Rays, wherein Heat con- 

 Efts, before he arife again : But under the Pole 

 the long abfence of the Sun for 6 Months, where- 

 in the extremity of Cold does obtain, has fo 

 chill'd the Air, that it is as it were frozen, and 

 cannot, before the Sun has got far towards it, 

 be any way fenfible of his prefence, his Beams 

 being obftrucled by thick Clouds, and perpe- 

 tual Fogs and Mills, and by that Atmolpherc 

 of Cold, as the late Honourable Mr. Boyle was 

 pleafed to term it, proceeding from the ever- 

 lalling Ice, which in immenfe Quantities does 

 chili the Neighbouring Air, and which the too 

 foon retreat of the Sun leaves unthawed, to en- 

 creafe again, during the long Winter that fol- 

 lows thij^fliort interval of Summer, But the 

 differing Tftegrees of Heat and Cold, in differ- 

 ing Places, depend in great rraafure upon the 

 Accidents of the Neighbourhood of high Moun- 

 tains ,
