642 THE LYMPHATICS. 



small lobules disseminated along the great curvature to the attachment of the 

 great omentum. 



The vessels which emerge from them " gather on the track of the gastric 

 arteries and veins, and ascend to the great tuberosity, near the trunk of the 

 cceliac artery ; there they anastomose with the lymphatics derived from the 

 spleen and liver, and unite into several flexuous branches, some of which 

 open directly into the thoracic duct, to which the others pass, after being 

 confounded with the anterior trunk of the intestinal lymphatics." — Colin. 



6. Glands and Lymfhatib Vessels of the Spleen and Liver. 



" The lymphatic vessels of the spleen, rising some from the interior of 

 the viscus, others from its surface, pass towards the splenic artery and vein ; 

 they traverse several groups of glands disposed on the track of these vessels, 

 commencing from the middle of the length of the fissure, ascend, five or six 

 in number, towards the origin of the artery in forming a sinuous mass whose 

 divisions, anastomosing with those of the stomach and liver, open, on the 

 one hand, with the latter in the anterior trunk of the intestinal lymphatics, 

 and, on the other, into a magnificent plexus communicating directly with 

 the thoracic duct. 



'■ Finally, the lymphatics of the liver form a very close network on the 

 surface, and another in the interior of the parenchyma. They collect towards 

 the posterior fissure, and first dip into a primary and very small glandular 

 group, then into a second group of voluminous round glands, which are 

 concealed between the trunk of the vena portsB and the pancreas. They 

 open in common with the vessels of the stomach and spleen." — Colin. 



GLANDS AND LYMPHATIC VESSELS OF THE ORGANS CONTAINED IN THE 

 THORACIC CAVITY. 



We find annexed to these organs three groups of lymphatic glands : 

 1, A series of small granulations placed in the posterior mediastinum, on 

 the course of the oesophagus ; 2, The hronchiql glands, situated in the angle 

 of bifurcation of the trachea, around the origin of the bronchi, which they 

 follow for a short distance into the pulmonary parenchyma; 3, Two long 

 strings of lobules extended on the sides of the inferior face of the trachea, 

 from the base of the heart to near the first rib. 



The first group receives the posterior lymphatics of the oesophagus, the 

 second those of the lung, and the third those of the pericardium, heart, 

 and a portion of the trachea and oesophagus. Their efierents, uniting into 

 some large trunks, enter the thoracic duct at different distances. 



GLANDS AND LYMPHATIC VESSELS OP THE THOEAOIO WALLS. 



These glands form three series : 1, A double chain of rounded grains, 

 situated on each side of the dorsal colunm, above the intercostal spaces, and 

 beneath the costal pleura ; 2, A frequently voluminous mass, lodged at the 

 base of the xiphoid appendix, behind the heart, and in front of the inferior 

 part of the diaphragm; 3, Some rudimentary granulations lying beside the 

 internal thoracic vessels. 



The lymphatics of the diaphragm, after receiving those from the convex 

 face of the Uver, pass to the glands placed at the base of the muscle, from 

 which they escape in the form of several canals that accompany the 

 internal thoracic vessels, and open into the anterior extremity of the thoracic
