440 INTRODUCTORY. 



X. Cetacea. The bodies of the animals composing this 

 order, are shaped like those of fishes, terminated by an appen- 

 dage nearly allied to the fin tail, which is cartilaginous and hori- 

 zontal ; the head is joined to the body by a very short, thick 

 neck ; they have two teats, which are either pectoral or abdo- 

 minal.

Alan, who stands at the head of created beings, consists but 

 of one species. When he enters the world, he is a defenceless 

 and helpless creature : he remains in a state of infancy longer 

 than any other animal, and attains maturity from the years 

 of twelve to twenty according to the latitude. Speech and 

 reason, which place him above all other creatures, are but 

 germs, which do not ripen of themselves, but are evolved by the 

 aid of culture and education. His instinct seems inferior to 

 that of most other animals : for, they possess internal impulses, 

 peculiar to their kinds, by which they can provide for themselves, 

 and form habitations for their young : while man is entirely 

 destitute of these instincts. The Almighty has, however, given 

 him in their stead, reason and reflection. He has, besides, a 

 voice, by which he can give utterance to infinite modifications
