THE rOLAll WORLD, 



WESTERN HEMISPIIEKE. 



[In the Western Hemisphere, the Polar World includes the space between the 

 Pole and latitude 50° North, and between the Pole and latitude 40° South. The 

 Temperate Zones are between latitude 50° and 30^ North, and 40° ? ad 30° South. 

 Thus in the Western Hemisphere the two Polar regions are 10° broader, and the 

 Temperate Zones 10° narrower than in the Eastern Hemisphere.]
