ON THE EXTERNAL SENSES OF ANIMALS. 



as to another leviathan, we may well apply the forcible description of the 

 Book of Job, " at whose appearing the mighty were afraid, and who made 

 the deep to boil as a cauldron : who esteemed iron as straw, and brass as 

 rotten wood ; who had not his like upon the earth, and was a king amidst 

 the children of pride."* 



Over this recondite and bewildering subject skeptics have laughed and 

 critics have puzzled themselves ; it is natural history alone that can findus 

 a clue to the labyrinth, that enables us to repose faith in the records of 

 antiquity, and that establishes the important position, that the extravagance 

 of a description is no argument against the truth of a description, and 

 that it is somewhat too much to deny that a thing has existed formerly, 

 for the mere reason that it does not exist now. 



♦ Job xK. 25. 27. 31. 33, 34.
