We noticed aboved that in the Palaeozoic Period, 

 Fishes were the dominant Vertebrates, we have seen 

 that the Mesozoic Period was the Reign of Reptiles, 

 we shall now see that the Mammals (as yet so feebly 

 represented) will be the rulers of the Cainozoic or the 

 Recent Era. The Cainozoic (Recent Life) Period re- 

 presents Animal Life in higher and still advancing 

 forms. This Period, as stated above, is divided into the 

 Eocene, Miocene, Pliocene and Pleistocene Eras. The 

 two first are more conveniently known under the 

 designation of Tertiary and the two last of Post- 

 Tertiary Periods, these distinctions are made to 

 facilitate the comprehension of Geological progression. 

 In the Tertiary Epoch, Animal Life as well as Plant 

 Life attain their improved and beautified stages ; it is 

 useless for us to search for those Ammonites, Belem- 

 mites and other innumerable Foraminiferous forms 

 which crowded the Ocean, all these have given way to 

 miscroscopic Molluscs and other Foraminifers and 

 Nummulites which in legions swarm the seas, and by 

 the continuous dropping of their calcareous deposits 

 coat the earth with a thicker crust. The soil in this 

 Period becomes more firm and thicker, and what with 

 the abundant vegetation, and the flowers that now 

 for the first time adorn the Forest and the Field, and
