 facet, but its attachments to this bone do not admit of such 

 accurate description. 



In the majority of cases the portion which passes from the 

 inferior extremity of the tibial attachment, and which forms 

 the free crescentic margin mentioned above, passes inwards and 

 backwards (when the bones are in apposition), and is attached 

 to the rim of the fibular facet along its inner angle. Between 

 these two attachments the ligament is most free, and, on pulling

 which the ligament described in the text formed an incomjdete septum

 interval is left between the fibular shaft and the inner 

 aspect of the ligament. Inferiorly the ligament blends with 

 the capsular ligament on its deep aspect along the line of attach- 

 ment of the capsular ligament to the fibula. The free cres- 

 centic margin of the ligament, on putting the two bones into 

 apposition, is approximated to the plane of the fibular facet 

 along its lower border. The portion which passes from the 

 other extremity of the tibial attachment is shorter, and is in
