when, having remarked in an animal an extraor- 

 dinary structure, we come at length to find out an 

 unexpected use for it. The following narrative 

 furnishes an instance of this kind. The baby- 

 roussa, or Indian hog, a species of wild boar, 

 found in the East Indies, has two lent teeth, more 

 than half a yard long, growing upwards, and 

 (which is the singularity) from the upper jaw. 

 These instruments are not wanted for offence ; 

 that service being provided for by two tusks issu- 

 ing from the under jaw, and resembling those of 

 the common boar : nor does the animal use them 

 for defence. They might seem, therefore, to be 

 both a superfluity and an encumbrance. But ob- 

 serve the event : — the animal sleeps standing ; 



argument in the text. Indeed, it is not inferior to the means em- 

 ployed for giving rapidity of motion to the membrana nictitans of 

 the eye of the bird.
