LYMPHATIC SYSTEM. 621 



deeper parts of the penis, the clitoris, and the vesiculee 

 seminales, like those of the uterus, enter the glands 

 along the internal iliac artery, the ovarian have a higher 

 termination; the large rectal lymphatics proceed to the 

 sacral and lumbar glands, and those of the testes accom- 

 pany the spermatic arteries to enter the latter glands, and 

 the renal and suprarenal lymphatics have the same termina- 

 tion. The splinic absorbents accompany the blood-vessels, 

 form a series of small glands ; receive the lymphatics of the 

 pancreas, and part of those from the stomach, and pro- 

 ceed with the lacteals towards the general receptaculum ; 

 those from the superficial and the interior parts of the 

 liver, proceed partly through the diaphragm and medias- 

 terium to the right lymphatic duct, and partly backwards 

 to the great left thoracic or chylo-lymphatic duct, both 

 sets forming numerous glands in their course. Both the 

 superficial and the deep-seated absorbents of the lungs 

 meet in the bronchial glands, and the efferent ducts of 

 these small glands ascend to terminate respectively in the 

 right and left thoracic ducts ; the lymphatics of the heart 

 accompanying the coronary vessels to the base of that organ, 

 and forming glands in their course, likewise ascend by the 

 sides of the trachea to open into both thoracic ducts, and 

 those cf the thyroid gland have a similar double termination. 

 The lymphatic glands or ganglia thus extensively developed 

 on all the absorbent trunks in man and mammalia, appear to 

 exert an influence in animalizing the serous residue of nutri- 

 tion which they convey, as the chyliferous glands exert on 

 the chyle they convey to nourish the blood. 



As in other parts, the absorbents from the head and neck 

 follow chiefly the course of the sanguiferous vessels, the su- 

 perficial generally accompanying veins, and the deeper-seated 

 the arterial trunks, and forming numerous small glands in 

 every convenient part of their course. The lymphatics 

 which descend with the temporal artery on each side, tra- 

 verse the zygomatic and parotid lymphatic glands, and con- 

 tinue to the numerous glands of the neck lying near the 

 junction of the external jugular with the subclavian vein ; 

 those which descend posteriorly with the occipital artery, tra- 

 verse the post- auricular glands, and terminate with the former 

 in the cluster of cervical glands. The numerous exterior ab-
