 antagonist to the powerful pronators to be described 

 further on. 



76. The flexor metacaiyi radialis^ is the lowest of 

 the group of three muscles on the outer aspect of a 

 Raven's forearm. Its mode of origin is very interesting, 

 for we find it arises by two distinct tendinous heads, 

 the longer one coming off from the external condyle of 

 the humerus, where it overlaps the origin of the siqnna- 

 tor hrevis, while the shorter one arises from the ulna 

 just without and rather beyond the base of the olecranon 

 process. In common with the others of the group of 

 muscles to which it belongs, it has a fusiform shaj^e for 

 the proximal moiety of the forearm, and is intimately 

 attached for its middle third to the interosseous 

 membrane. 



Rather beyond the middle of the shaft of the ulna the
