of the scapula, and is inserted, together with the 

 latissimus dorsi, by a flat tendon, on the humerus, 

 just below the lesser tuberosity, (Plates III. 

 and IV.) 



15. The Teres Minor is a much smaller muscle 

 which arises from the lower half of the axillary 

 margin of the scapula, and is inserted on the great 

 tuberosity of the humerus, just below the inser- 

 tion of the infraspinatus muscle. (Plate III.) 



Reflect the rhomboideus major, and rhomboideus 

 capitis muscles. 



1 6. The Levator Anguli Scapulae is the thick mus- 

 cle which takes its origin from the transverse 

 processes of the last five cervical vertebrae, and is 

 inserted on the anterior half of the vertebral mar- 

 gin of the scapula. (Plates III. and IV.) 



1 7. The Serratus Magnus is the large muscle con- 

 tinuous with the posterior margin of the levator 

 anguli scapulae. It arises by digitations from the 

 first nine or ten ribs, and is inserted on the poste- 

 rior half of the vertebral margin of the scapula. 

 The serratus magnus and levator anguli scapulae 

 form a single sheet of muscle, which suspends the 

 body from the fore-limbs. (Plates III. and 

 IV.) 



18. The Subscapularis is the muscle which fills 

 the entire subscapular fossa. It takes its origin 

 from the greater part of the fossa, from which its 

 fibres converge to their insertion, by tendon, on
