 outer surface of the costal process of the sternum and 

 the contiguous outer surfaces of three or four of the 

 hsemapophyses, in which situation it is largely over- 

 lapped by the pectoralis tertius. Its outermost sheath 

 of fascia is attached to the inferior external maroin 

 of the corresponding coracoid Ijone, l)ut its short and 

 oblique muscular fibres pass over this to be inserted 

 and fill the fossa that is found at the lower third of 

 the posterior aspect of the coracoid. When this muscle 

 contracts it simply pulls the coracoid very slightly 

 outwards, the bone sliding along upon the articulation 

 of its sternal bed. The more important function of
