opened. If they watch the movements of the eyes, 

 they may observe that the rabb ; t can turn his eyeball 

 toward his tail, and see behind him with little movement 

 of the head. 



Nose. Position : very freely movable, and almost 

 constantly in motion. Small, as compared with most 

 animals. Naked at tip (compare with cat or dog), 

 with V-shaped partition between two openings, or nos- 

 trils. 



" Whiskers" Position: at side of mouth and below 

 eyes. Compare with cat's " whiskers." Are said to aid 

 rabbit in feeling, and to tell him whether any opening 

 his head may enter is large enough for his body to pass 

 through. 



Adaptation. Advantage of position, form, size, and 

 freedom of movement of ears ; use of hairs on inside. 

 Advantage of having eyes on side of head ; of having 

 them stand out so far from head; use of "third eye- 

 lid " if rabbit does not shut his eyes. 



Summary. With topics below written on blackboard, 

 have pupils tell orally, with as few questions as possible, 

 all they can about 



The head: position with reference to body, shape, 

 size. 



The ears: position, movements, shape, size, how 

 adapted to rabbit's use. 



The eyes: position, parts as compared with pupils' 

 eye, how adapted to needs of rabbit. 



The nose : position, movements, size, covering, open- 

 ings.
