lymphatics, lying near the 

 commencement of the basilic 

 vein, a little above and in front 

 of the inner condyle of the 

 humerus. 



The axillary glands are 

 generally ten or twelve in num- 

 ber : they vary, however, con- 

 siderably in their number as 

 well as in their size, in diiferent 

 individuals ; they are mostly 

 placed along the axillary ves- 

 sels, and receive the lympha- 

 tics which ascend from the 

 limb ; but a few also lie 

 further forwards on the ser- 

 ratus magnus near the external 

 mammary artery, and beneath 

 the pectoral muscles, and 

 receive the lymphatics from

 Shoulder, and Upper Limb, from before (after 

 Mascagni, A. T.) | 



The lymphatics are represented as lying upon the deep 

 fascia. 



a, placed on the clavicle, points to the external jugular 

 vein ; b, the cephalic vein ; c, the basilic vein ; d, radial ; 

 e, median ; /, ulnar vein ; (/, great pectoral muscle cut 

 and turned outwards ; 1, superficial lymphatic vessels 

 and glands above the clavicle ; 2, those below the clavicle 

 partly joining the foregoing and dipping into the triangu- 

 lar space between the deltoid and pectoral muscles ; 3, 

 lymphatic vessels and glands jilaced along the border ef 

 the axilla and gi-eat pectoral muscle ; 4, upper brachial 

 and axillaiy glands and vessels ; 5, two small glands 

 placed near the bend of the arm ; 6, radial lymphatic 

 vessels ; 7, ulnar lymphatic vessels ; 8, 8, palmar arch 

 of lymphatics ; 9, 9', outer and inner sets of vessels. 



the mamma and muscular walls of the chest ; 

 while others incline downwards at the pos- 

 terior boundary of the axilla, and are joined 

 by the lymphatics fi'om the back. 



From the glands of the axilla efferent 

 lymphatic vessels, fewer in number, but 

 larger in size than the afferent vessels, pro- 

 ceed along the course of the subclavian artery, 

 in some parts twining round it. From the 

 top of the thorax they ascend into the neck 

 close to the subclavian vein, and terminate — 

 those of the left side in the thoracic duct, 

 those of the right side in the right lymphatic 

 duct. Sometimes they unite into a single 

 trunk, which opens separately into the sub- 

 clavian vein near its termination.
