Relations. This muscle is covered by tho skin, panniculus caruosus, 

 dorsal portion of the trape/ins, and the mass of olecranian muscles. It 

 covers the infraspinatiis ; the cartilagi; of the scapula; the rhomboidous ; 

 the small anterior and posterior serrated muscles, whose aponeurosis is 

 directly joined to its own; the ilio-spinalis ; the principal glutcal ; a portion 

 of the external surface of the last ribs, to which its aponeurosis strongly 

 adheres; as well us the correspond ing external interooetals, and tho great 

 serrated muscle. 1>< t \\een the lust rib and the external angle of the ilium,
