The Axilla. 49 



artery with the nerve lying above it is found emerging 

 from the quadrangular space bounded by the teres major 

 below, teres minor above, scapular head of the triceps 

 internally, and the humerus externally. The operation 

 of stretching the lower part of the brachial plexus is not 

 often performed but may be done by means of the same 

 incision as employed in the ligation of the third part of 

 the axillary artery.
