An order of immense extent, that of the Ungulata, 

 or " hoofed" quadrupeds, forms the sixth division. 

 Here the largely-developed nails, called f( hoofs/' are 

 met with, and all four limbs are always developed. 

 The rhinoceroses, horses, pigs, ruminant animals 

 (sheep, deer, oxen, camels, &c.), hippopotamus, &c. r 

 represent this group. The seventh division is that of 

 the elephants (Proboscidea) , the characters of these 

 animals requiring no special mention. The hyrax, or 

 " coney " of Scripture, represents the eighth group, 

 and resembles the rodents or " gnawers " in some 

 respects, whilst it is also allied to the rhinoceroses, if 

 the form and structure of the molar or grinding teeth 

 are considered. The Carnivora, or lions, tigers, 

 wolves, dogs, bears, seals and walrus succeed, as 

 order the ninth ; and the Rodents, or gnawers, with 

 chisel-shaped front teeth, growing from permanent 

 pulps, and represented by the rats, mice, beavers, 

 squirrels, porcupines, &c., form the tenth division. 

 The bats, or Cheiroptera, with an elongated hand of 

 four fingers (and a short thumb), adapted to support 

 a flying-membrane, form the eleventh group. The- 

 Insedivora are the twelfth order, and present us with 

 the moles, shrews, and hedgehogs as types. The 

 Primates (including the Quadnimana, or monkeys, 

 and Bimana, or man) bring us at once to the con- 

 cluding order, and to the height of animal develop- 

 ment. 



Now, as regards the past history of the Mammalia, 

 there exists abundance of evidence to show that many
