lateral eminences with concave surfaces which receive the con- 

 dyles of the femur. The lower extremity is much smaller than 

 the upper; it is prolonged downwards on its 

 inner side into a strong process, the internal 

 malleolus. It articulates with the fibula and 

 one of the bones of the ankle. 



The fibula is situated at the outer side of the 

 leg. It is the smaller of the two bones, and, in 

 proportion to its length, the most slender of all 

 the long bones : it is placed nearly parallel with 

 the tibia. The upper extremity consists of an 

 irregular rounded head by 

 means of which it articu- 

 lates with the tibia. The 

 lower extremity is pro- 

 longed downwards into a 

 pointed process, the external 

 malleolus, which lies iust
