OF THE UPPER EXTREMITY. 487 



The superficial lymphatic glands are few, and. of small size. There are occa-

The deep lymphatic glands are also few in number. In the forearm a few 

 small ones are occasionally found in the course of the radial and ulnar vessels ;

The axillary glands are of large size, and usually ten or twelve in number. 

 A chain of these glands surrounds the axillary vessels, imbedded in a quantity of 

 loose areolar tissue ; they receive the lymphatic vessels from the arm ; others are

 series, a small chain running along the lower border of the Pectoralis major, as
