Section VII.- 



Of the Temperature of the Southern Hem'ifphere..: 



That the fouthern hemifphere is colder than the northern is- 

 the general opinion, i Gentil Voy. p. 1 14. That it is fo, during, 

 its fummer feafon, can fcarce be denied, at leaft in latitudes above 

 4o'3. 



But the winter of this hemifphere feems not to be as cold as 

 ours between the fame parallels (fee Eftimate of the temperature 

 of different latitudes, p. 51) the higher latitudes are rarely na- ■ 

 vigated during their winter. . 



CEpinus, reafdning on aftronomical principles, attributes the 

 inferior temperature of the fouthern hemifphere to the fhorter 

 abode of. ihe fun in the fouthern tropic, fhorter by feven days, 

 which produces a difference of fourteen days in favour of the 

 northern hemifphere, during which more heat is accumulated ; 

 and hence he. infers that the temperature of the northern hemif- 

 phere is to that of the, fouthern as 189,1; to 175,5 or as 14 to ij,
