THE STUDY OF THE RABBIT. 71 



Limbs. Review what was learned in Lesson II. about 

 usual means of locomotion, hopping and jumping. How 

 many times as far can the rabbit jump as the child, 

 keeping in mind their relative size. 



Have children tell about their own legs and arms, 

 their position, relative size^ the direction of motion and 

 comparative freedom of motion of arms and legs, the 

 three divisions of each (upper arm, fore arm, and hand, 

 and thigh, leg, and foot), and the direction of motion 

 at the joints, at knee, ankle, elbow, and wrist. Have 

 them note and show how, when ready to jump, they 

 stand on their toes, with legs flexed at ankle and 

 knee, and spring by suddenly straightening these 

 joints. 



Position and attachment and covering of legs of 

 rabbit. Greater freedom and range of motion of fore 

 legs. Greater size and strength of hind legs. 



Parts of hind leg. Thigh, leg, and foot. Compare 

 with child's leg. Thigh very short, with joint corre- 

 sponding to child's knee close to the rabbit's body. 

 Leg, corresponding to part of child's leg between knee 

 and ankle, long and strong. Prominence of ankle 

 joint. Part below the ankle joint, corresponding to 

 child's ankle and foot, greatly lengthened. Cushion 

 or pad near end of foot covered with brush-like hairs. 

 How many toes on each hind foot ? Are they movable ? 

 Do they spread out? Compare legs, toes, and claws 

 with those of cat or dog. 



Fore limbs. Relative size of parts and character of 

 joints, as compared with similiar divisions o
