The development of the Southern fauna and flora occurred, Mr. 

 Forbes believes, during the Ice Age of the Northern Hemisphere 

 when "Antarctica" rejoiced in a semi-tropical climate. Their dispersion 

 occurred during the slow oncome of the partial glaciation of the 

 Southern Hemisphere, which exists now. 



The occurrence of many southern forms of life in the Miocene of 

 France and other parts of Europe is explained, according to the 

 author, by their having been driven north during a cold, or perhaps 

 glacial, period in the Southern Hemisphere in that age, of which 

 there are evidences in various parts of South Africa, Australia, and 

 South America, corresponding to the warm epoch in the Miocene age 

 in northern latitudes.
