THE REASON WHY: 



When with a Reaumur s skill thy curious mind 



Has classed the inseei tr.bes of human kind, 



Each with its busy hum, or gilded wing, 



Its subtle web- work, or its venomed sting.&quot; ROGERS. 



166. Why is the term invertebrated unemployed? 

 Because it is merely of a negative character. 



[All animals may be referred to one or other of the foregoing 

 those not included in the first Division are all invertebrated.] 



, and 



SO MUCH O7 THE CLASSIFICATION AS WILL BE GIYEN IN 7BE FOLLOWING PAGES IS 

 A COMBINATION OF TDK SYSTEMS OF LlNN^US AND ClJVIER, WITH SVCH 

 MODIFICATIONS AS ARE NOW GENERALLY ADOPTED. 



DIVISION I. VERTEBRA CLASS I. MAMMALIA. 



ORDER I. BIMANA. 



167. What is the meaning of the term Bimana ? 



It is derived from the Latin bis, twice, and manus, a hand : it 

 means two-handed. 



168. Why is MAN the only individual included in this order ? 

 Because he is the only two-handed animal. This fact will be 



further enforced by reference to 



ORDER II. QUADRUMANA. 



169. What is the meaning of the term Quadrumana? 



It is derived from the Latin quadra, four, mam s, hand, and 

 means four-handed. 



170. Wliy are monkeys described as four-handed ? 



Because those of their extremities which are apparently 

 analogous to the feet of man, are 

 provided with thumbs, free and oppos- 

 able to the other toes the toes them 

 selves being long and similar to the 

 fingers of the hand. 



In consequence of this peculiarity, all 

 the species of the order exhibit the 

 utmost facility in climbing trees, but 

 cannot sustain themselves, much less 

 walk, in an erect posture without considerable difficulty.
