244 THE MYOLOGY OF THE RAVEN. 



is one of tlie largest of these perforated flexors the 

 tendons of which go to the toes. 



It is found at the antero-external aspect of the 

 leg, and arises by a strong fascia that merges with 

 the fascia of the knee-joint. It also arises by a strong 

 tendon, in common with the tendon of the flexor 

 perforatus indicis secundus j^edis, from the outer side 

 of the external condyle of the femur. The muscles 

 of the anterior aspect of the til^ia also blend with it, 

 more or less above, by a common fascia ; while below 

 we find it has a semi-tendinous attachment with the 

 lower end of the filnila, and a line on the tibial shaft 

 for a short distance below it.
