of the pancreas; they receive the lymph vessels from the capsule and from 
the substance of the spleen. Their efferent vessels, accompanied by some of 
the lymphatics from the left part of the great curvature of the stomach, pass 
inwards in the leno-renal ligament and terminate in the cceliac glands. 
The hepatic glands (lymphoglandule hepatice) are situated in the upper part 
of the small omentum below the transverse fissure of the liver; they receive the 
deep lymphatics of the liver which accompany the branches of the portal vein, 
and many of the superficial lymphatics from the under surface of the liver. 
Their efferent vessels accompany the hepatic artery and terminate, in the eceliac 
elands. 
The pancreatic glands (lymphoglandule pancreatic) le along the upper 
border of the pancreas behind. the small sac of the peritoneum; they receive the 
lymphatics which issue from the pancreas and from the diaphragmatic glands, and 
their efferent vessels terminate in the cceliac glands. 
The mesenteric glands (lymphoglandule mesenteric) are numerous (100 to 
200); they are scattered between the layers of the mesentery, and are most 
numerous in that portion of the mesentery which is connected with the jejunum. 
They vary in size, but the largest are rarely larger than an almond; the smaller 
glands lie near the intestine, and the larger near the attached border of the 
mesentery. They receive afferent vessels from the walls of the jejunum and ileum, 
and from the ascending colon, the ceecum, and the transverse colon. Their efferents 
terminate in the pre-aortic glands. 
The ileo-colic glands are situated in the lowest part of the mesentery near 
the angle between the ileum and the ascending colon. They receive afferent 
vessels from the lowest part of the ileum, from the cecum, and from the vermi- 
form appendix, and their efferent vessels pass, with those of the other mesenteric 
glands, into the pre-aortic glands. The ileo-colic glands are four or five in 
number, and occasionally one of them, the appendicular gland, is separated from the 
rest, and is placed in the base of the mesentery of the vermiform appendix. This 
gland is of special interest, not only because it receives the lymphatics of the 
appendix, but also because in the female some of the lymphatics of the right ovary 
terminate in it. 
The colic glands which lie in relation with the ascending and descending 
portions of the colon and in the transverse and iliac mesocolic folds of the 
peritoneum. They receive the lymphatic vessels which issue from the portion of 
the gut in their immediate neighbourhood, and their efferent vessels terminate in 
the lumbar and pre-aortic glands. 
The rectal glands are a few small glands which le in the meso-rectum; they 
receive lymphatic vessels from the upper part of the rectum, and their efferent 
vessels terminate in the lumbar and sacral glands. 
The celiac glands (lymphoglandule cceliacee) surround the cceliac axis, and 
lie in front of the abdominal aorta above the origin of the superior mesenteric 
artery. They vary in number, and are of large size; they receive the efferent 
vessels from the gastric, splenic, pancreatic, and hepatic glands, and their efferent 
trunks unite with the efferents from the pre-aortic glands, and form with them 
a single trunk, the common intestinal lymphatic trunk, which terminates in the 
receptaculum chyli. 
(2) The parietal glands of the abdomen and pelvis are as follows :-— 
The external iliac glands which lie along the front and sides of the external 
iliac artery. The lower three are just above Poupart’s ligament, one lying to 
the outer side of the artery, one in front, and one to the inner side. The inner of 
these three receives the efferent lymphatics from the deep femoral glands. The 
afferents of the anterior gland come from the deeper parts of the lower and the 
middle portions of the abdominal wall in the area corresponding to the distribu- 
tion of the deep epigastric artery. The afferents of the outer gland which accom- 
pany the deep circumflex iliac artery, are derived frém the iliac fossa and from the 
deeper portions of the lower part of the lateral wall of the abdomen. The higher 
external iliac glands receive the efferents of the lower glands, and also other 
vessels from the lateral walls of the pelvis.
