230 THE MYOLOGY OF THE RAVEN. 



ill the Eaven a perfectly distinct muscle, and fully merits 

 a separate description. It arises, somewhat tendinous, 

 from the outer surface of the external condyle of the 

 femur, just below the external head of the gastrocnemius. 

 The fibres go to form a thin, flattened muscle, broadly 

 spindle-shaped, and about three centimetres long, with 

 its tendon merging with the spreading fascia of its outer 

 aspect. This tendon is rather wide for the most part 

 above, and very thin. It commences at the lower apex 

 of the muscle, and takes a straight course to the supero- 

 internal angle of the tibial cartilage, thus really passing 

 in an oblique line across the back of the leg. It be- 

 comes gradually smaller as it nears this cartilage, which 

 it passes through, superficially, to its outer side ; then 

 crossing to the tibio-tarsal joint, passes through a special 

 canal in the hypotarsus, in the median row to the inner 

 side. Its course is now directly down the back of the 

 tarso-metatarsus, under the annular ligament of the sole 

 of the foot, and a cartilaginous block beneath it to hold
