Practical Zoology. 



bones of the palm are the metacarpal bones. Beyond them are 

 the finger bones, or phalanges. Find how many there are of 

 each of these sets. 



9. In the hind limb each half of the pelvis consists of the loi 

 hip, or innominate bone. Note the deep socket of the ball-and- 

 socket joint. Fitting into this is the rounded head of the femur, 

 or th'igh bone. Compare this joint with that of the shoulder. 

 Which has the greater range of motion ? Which the greater 

 strength ? Study the kneejoint. Note the kneepan, or patella, 

 in the tendon running over the kneejoint. The large bone of 

 the leg, or shank, is the tibia. Beside it is the fibula; is it 

 wholly free from the tibia ? If it is found united with the tibia, 

 where and to what extent? Corresponding to the carpus of the 

 wrist, there is a series of short bones in the foot constituting 

 the tarsus. Then comes a row of longer bones, the metatarsal 

 bones. And after these are the toe bones or the phalanges. How 

 many in each of these series and how arranged ? Are the bones 

 of the same number as in the fore limbs ?
