    it dips down to join the axillary, and of the external anterior thoracic nerve [516] which comes forwards on the upper side of the axillary artery to supply the muscle. On removal of some adipose tissue, the sub- clavicular space will now be seen, bounded externally by the upper part of the pecloralis minor [259], and in it the costo-coracoid membrane [269], attached to the clavicle above and continuous below with the sheath of the axillary vessels j also the superior thoracic and acromio-thoracic arteries [435-6], with the humeral branch of the latter lying along the cephalic vein. The costo-coracoid membrane is to be removed to expose the subclaims muscle [259] and the axillary vessels and the nerves of the brachial plexus will be brought into view [434, 514]. The axillary space is now to be dissected from below, the sternal part of the great pectoral muscle remaining intact; and to enable the arm to be ex- tended at right angles to the trunk, a board may be slipped beneath the shoulder. With a view to the study of the connections of the axillary fascia [269], the integument should be removed separately ; the fascia of the pectoralis major should then be reflected from the border and deep surface of that muscle till its continuity with. the investment of the pectoralis minor is seen ; then the fascia concealing the latissi- mus dorsi should be divided and traced forwards till the continuity of the axillary fascia with the pectoral fascia, the axillary sheath of the vessels and the apo- neurosis of the arm is seen. The adipose and other contents of the space are to be separated with the help of the handle of the scalpel as much as possible
