 and accommodates itself to the light 

 around.

 the DARK? 



A. Because they have the power of 

 enlarging the pupil of their eyes, so as to 

 collect several scattered rays of light ; in 

 consequence of which, they can see 

 distinctly when it is not light enough for 

 us to see any thing at all.

 broad, daylight fatigues them; so they 

 close their eyes for relief.

 and they keep shutting their eyes to 

 relieve the sensation of too much light.
