and the mylo-hyoideus and subscapulo-Lyoideus muscles on the other, above and 

 near to the facial artery. The lymphatics of the tongue, cheeks, lips, nostrils, 

 and nasal cavities join these glands. Their efferents reach the pharyngeal or 

 guttural glands. 



4. Prescapular Glands. 



By their union these form a kind of chain, at least twelve inches in length, 

 placed on the course of the ascending branch of the inferior cervical artery, 

 beneath the internal iace of the mastoido-humeralis muscle, and descending 

 close to the attachment of the sterno-maxillaris muscle. 



The majority of the lympliatics of the neck, and those of the breast and 

 shoulder, open into these glands. Their efi'ereuts, short and voluminous, enter 

 the prepectoral glands. 



5. Brachial Glands. 



Situated beneath the anterior limb, inside the arm, these vessels are divided 

 into two groups — one placed near the ulnar articulation, within the inferior 

 extremity of the humerus ; the other disposed in a discoid mass behind the

brachial vessels, near the common insertion of the teres major and latissimus 

 dorsi. 



The first group receives the vessels from the foot and the forearm, wnich 

 accompany the superficial veins, or pass with the deep arteries and veins into 

 the muscular interstices. It sends nine or ten flexuous branches to the second 

 group, into which open directly the lymphatics of the arm and shoulder, and 

 from which emerge a certain number of efferents that pass, in company with the 

 axillary vessels, to the prepectoral glands. 



Article III. — Great Lymphatic Vein. 



The second large receptive trunk of the lymphatic vessels, this great vein 

 (the durfus h/mphatirm dextn) leaves the prepectoral glands of the right side, 

 and therefore becomes the general confluent of the lymphatics from the right 

 anterior limb, the right axillary and superficial costal regions, as well as the 

 right half of the head, neck, and diajthragm. 



This trunk is only from three-fourths of an inch to two inches in length.
