SECTION II. 

 THE ANIMAL KINGDOM. 



§ 13. Animals are animate beings, possessing feeling 

 and the power of voluntary motion. 



§ 14. Those animals are called carnivorous, which derive 

 their food from the animal kingdom ; herbivorous, which 

 feed on vegetables ; and omnivorous, which feed on flesh 

 and vegetables. 



\\6.. Mind, as shown through reason or instinct, is 

 manifested in every grade of animated life : reason is 

 the sole property of man ; instinct, of animals. 



§ 16. Reason is susceptible of improvement and cul- 

 tivation ; and hence the need of education, which is calcu- 

 lated to improve the mental powers. 



§ 17. Instinct is a faculty belonging only to animals, by 

 means of which they perform from an internal impulse, 

 and without any instruction, certain actions tending to 

 their own support and that of their offspring ; thus the 

 bird builds its nest, and the bee constructs its comb, as 

 perfectly at* first as after successive trials. 



§ 18. The Animal Kingdom is usually divided into six 

 classes, viz : 



I. Mammalia, (Mammalia.) or red and warm blooded 

 viviparous animals. 



II. Birds, (Aves,) or red and warm blooded oviparous 

 animals. 



III. Reptiles, (Reptilia,) or red and cold blooded ovip- 

 arous animals, provided with lungs, and destitute of 

 fins ; as snakes, lizards, turtles, frogs, etc. 



IV. Fishes, (Pisces,) or red and cold blooded ovipa- 

 rous animals, provided with fins, and destitute of lungs. 



V. Insects, (Insecta,) oviparous animals, provided with 

 at least six legs, and destitute of a bony frame ; aa 

 beetles, locusts, butterflies, wasps, flies, and spiders. 



VI. Worms, (Vermes.) or soft animals with, or without 

 hard coverings, and destitute of legs ; as the rainworm, 

 the shellfish, etc.
