. MAN. 11 



Fish, correspond to one another in their most important 

 features, each being modified according to the use for 

 which it was made. This is quite plainly seen by study- 

 ing Figs. 23-33, and observing that the corresponding 

 parts are marked with the same letter. 



The Vertebrates are divided into Mammals, Birds, 

 Reptiles, Batrachians, and Fishes. 



MAMMALS. 



The Mammals are vertebrates which bring forth liv- 

 ing young and nourish them with milk. Man, Mon- 

 keys, Beasts of Prey, Hoofed Animals, Whales, Bats, 

 Moles, Squirrels and Rats, Sloths, Kangaroos and Opos- 

 sums, and Duckbills, come under this head. They all 

 breathe air by means of organs called lungs, have warm 

 blood which is sent throughout the body by means of a 

 heart constructed like that of Man, and the neck has 

 only seven vertebrae. 



MAN. 



Man is at the head of the Animal Kingdom. He is 

 the only animal to whom the upright position is nat- 

 ural ; the only one which has a perfect hand ; the only 

 one whose forward extremities arms and hands are 

 not used for locomotion ; the only one that laughs ; the 

 only one that speaks a language ; and his brain is larger 

 than tkat of any other animal,* and he can live in all 

 countries. But Man is also far more than an animal. 

 He has a Mind and a Soul. He can learn much about 

 the things which God has made, and understand the 

 Bible which He has given. 



* The brain of the Elephant and of the Whale is said to be larger than 

 tit at of Man.
