front and side of the abdomen, or the hand, forearm, and arm, the axillary glands are liable to 

 be found enlarged. 



The lymphatic vessels of the upper extremity are divided into two sets, super- 

 ficial and deep. 



The superficial lymphatic vessels of the upper extremity commence on the fin- 

 gers, two vessels running along either side of each finger, one on the palmar and 

 the other on the dorsal surface. Those on the palmar surface form an arch in the 



Axillary glands.

palm of the hand, from which are derived two sets of vessels, which pass up the 

 forearm, taking the course of the subcutaneous veins. The lymphatics from the 

 dorsal surface of the fingers form a plexus on the back of the hand, and, winding 

 around the inner and outer borders of the forearm, unite with those in front. Those 

 from the inner border of the hand accompany the ulnar veins along the inner side 

 of the forearm to the bend of the elbow, where they are joined by some lymphatics 

 from the outer side of the forearm : they then follow the course of the basilic vein, 

 communicate with the glands immediately above the elbow, and terminate in the 

 axillary glands, joining with the deep lymphatics. The superficial lymphatics from
