 lip of the linea aspera, between the Adductor magnus and Vastus externus, extend-

 prolongation of the linea aspera to within two inches of the outer condyle, and 

 from the external intermuscular septum. The fibres of the long head form a fusi-

form belly, which, passing obliquely downward and a little outward, terminates 

 in an aponeurosis which covers the posterior surface of the muscle, and receives 

 the fibres of the short head; this aponeurosis becomes gradually contracted into 

 a tendon, which is inserted into the outer side of the head of the fibula, and by a 

 small slip into the lateral surface of the external tuberosity of the tibia. At its 

 insertion the tendon divides into two portions, which embrace the long external 

 lateral ligament of the knee-joint. From the posterior border of the tendon a
