considerable upward oscillation of 120 to 200 higher than now occurred, 

 with the following depression a few feet lower than now ; again a slight 

 elevation represented by the modern raised Coral reefs, but we do not say 

 whether the movement of the present day is one of rising or sinking. 

 Thus we absolutely find, commencing with the Mio-Pliocene broad 

 lands, no less than four epochs of elevation separated by those of sub- 

 sidence. But most of these movements have been of small amounts, 

 every one in each direction having reached gigantic proportions. These 

 numerous terrestrial changes are also recorded in Cuba and on the 

 Continent.
