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

 great omeutum. 



The vessels which emcrgo from them "gather on the track of the 

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

 cieliac artery; there they anastomose with the lymphatics derived 1'mm ilu; 

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

 open directly into tho thoracic duct, to which the others pas:-;, after being 

 confounded with the anterior trunk of tho intestinal lymphatics." Colin, 



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



" Tho 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 tho 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 portte and the pancreas. They 

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



GLANDS AND LYMPHATIC VESSELS OF THE OBGANS CONTAINED IN THE 

 THOUACIO CAVITY. 



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

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

 the course of the oesophagus ; 2, The bronchial glands, situated in tho 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 tho 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 tho third those of the pericardium, heart, 

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

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



GLANDS AND LYMPHATIC VESSELS OF THE THORACIC WALLS. 



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

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

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

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

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

 internal thoracic vessels. 



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

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

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