ZOOLOGICAL REGIONS. 



Sea to the latitude of Edinburgh in the British Islands. On the Pacific coast of Asia the 

 July isothermal of G0° is depressed still further south, almost to the latitude of the Pyrenees, 

 apparently by the cold stored in the nearly land-locked Sea of Okhotsk. 



In South Africa the isothermal of 77° is raised towards the equator on the 'west coast 



by a cold current from the Antarctic Ocean, but is depressed down to the tropic of Capricorn 

 on the east coast by the warm Mozambique current, though the effect of the latter is 

 diminished inland by the rapid rise of the Drakenberg Range. 



In South America somewhat similar causes produce the same effect. Humboldt's 

 current raises the isothermals on the coasts of Chili and Peru, its effects being increased 

 inland by the rapid rise of the Andes.
