which passes the tendon of one head of the in. ftennteniHnosus (Fig-. 

 83 st"} ; (fj} a second part arises from this same tendon (Fig. 83 stf") 

 and joins with the first part. Thus formed the muscle passes to be 

 inserted into the distal half of the inner surface of the femur as 

 far as the condyle. Near its hinder extremity, however, it passes 

 on to the dorsal and outer surfaces, and thus forms a kind of 

 muscular sheath surrounding- the distal portion of the bone.

These two small muscles which lie under cover of the sartorins, addtir- 



tnr /onf/iift and magnus*, 

 appear externally as one 

 muscle, but may easily be 

 separated (Fig. 83). They 

 arise close together from 

 the pubic symphysis, and 

 are inserted into the 

 inner surface of the an- 

 terior half of the femur. 

 They are not attached to 

 the adductor ii/a;////'x.

This is a long thin mus-

 by two long thin tendons, 

 one (caput jjosficum, st'} 

 from the pubic symphysis,
