CLASSIFICATION OF ANIMALS. 331 



four, and mani hands. These have thumbs, or toes, separate, 

 on each of the four feet. We here find Orang-outang (some- 

 times called the wild-man), and the Monkey. 



The Third Order contains Carnivorous animals, or flesh- 

 feedersj having no separate thumbs, or great toes without 

 nails ; as the Dog and Cat. i 



The Fourth Order contains the Gnawers, having no canine 

 teeth (those which are called eye-teeth), feeding almost wholly 

 on vegetable substances ; as the Rat and Squirrel. 



The Fifth Order is Edentata, or animals wanting teeth ; as 

 the Sloth and Armadillo. 



The Sixth Order, Pachy derma, thick skin animals with 

 hoofs ; as the Elephant, Horse and Hog. 



The Seventh Order contains the Ruminating animals, such 

 as chew the cud, having front teeth (incisors) below only, and 

 feet with hoofs cloven, or divided ; as the Ox, Sheep and Camel. 



The Eighth Order, Cete, contains aquatic animals (such as 

 live in water), having no kind of feet, or whose feet are fin- 

 like-limbs ; as the Whale and Dolphin. 



We have enumerated all the orders of the class Mammalia, 

 as it is the one in which man is placed ; we shall now notice 

 the remaining classes of animals, without going into so minute 

 a detail of their orders. 



CLASS n, Contains Birds (Aves), which are distinguished by 

 having the body covered with feathers and down, long naked 

 jaws, two wings formed for flight, and bi-ped (from bis, two, 

 and pedes, feet). The orders in this class, are chiefly dis- 

 tinguished from each other by the peculiar make of the bill 

 and feet. 



CLASS in ? Amphibia, contains amphibious animals, includ- 

 ing what are commonly called reptiles. It is divided into four 

 orders : 



1st. With shells over their back, and four feet ; as the tor- 

 toise and turtle. 



2d. Covered with scales, and having four feet ; as the cro- 

 codile and lizard. 



3d. Body naked, destitute of feet ; as serpents and snakes. 



4th. The body naked, and having two, or four feet ; as the 

 frog and toad. 



CLASS iv, Contains Fishes (Pisces), natives of the water, 

 unable to exist for any length of time out of it ; swift in their 

 motions, and voracious in their appetites ; breathing by means 

 of gills, which are generally united in a long arch ; swimming 

 by means of radiate fins, and mostly covered with scales.
