the innumerable little winged creatures that find 

 shelter and food in the Botanical expanse, the Earth 

 puts on her mantle of beauty the Climates begin to 

 perform their beneficial operation on the vital evolution, 

 and we begin to recognize in the various Mammals 

 such as the Pachydermata, the Mastodons, Mammoths, 

 ( which are the kings of the Period ), the Meryco- 

 theres, etc., the predecessors of our Elephant, Tiger, 

 Rhinoceros, Hippopotamus and Camel. 



Progressing always upward and not only forward, 

 we find the great March of Life advancing to the 

 Glacial Epoch ( Northern Drift or Boulder Clay ) 

 which constitutes the Post-Tertiary or Quarternary 

 Period when icebergs Summer after Summer drift 

 over the waters " grinding their way through firth 

 " and strait dropping their burden of mud, sand and 

 ' gravel on the sea-bed, or stranding themselves on 

 " its shores." By and by the deposits become fossi-

 Animal-Life, till that time when the Land emerges 

 upwards still upwards, and the Continents of the 

 Northern Hemisphere assume their present configu-

The study of Palseonbology and its concomitant 

 the Science of Geology shows us that new species are 

 continually springing up in Botanical as well as in 

 Animal Life : kindred causes which have rendered 

 extinct our Dodo, the ^piornis of Madagascar and 

 the Dinornis of New Zealand, are extinguishing with
