the infant, but diminish with the rest of the structure in the 

 adult : they terminate in the bronchial glands also. 



SECT. VII. THE ABSORBENTS OF THE PARIETES OF THE TRUNK; 



In addition to the absorbents mentioned as belonging to the 

 internal and external parietes of the pelvis, there are some 

 others belonging to this cavity, as the ilio lumbar, the sacral* 

 and the circumflex. 



The Ilio Lumbar Lymphatics come from the parts to which 

 the artery of the same name is distributed, and, assembling into- 

 two or more large trunks which pass beneath the psoas magnus 

 muscle, one of them joins the lumbar glands, and another the 

 hypogastrie. 



The Sacral Lymphatics arise from the cellular tissue in front 

 of the sacrum and from the spinal canal in the latter. Emerging 

 through its foramina in front, they terminate in the lower par! 

 gf the lurnbar and in the hypogastric plexus. 



The Circumflex Iliac Lymphatics attending the artery of the 

 same name, arise from the lateral inferior parietes of the abdo- 

 men, in the thickness of its broad muscles; the several branches 

 assemble into a few trunks, which descend along the posterior 

 margin of Poupart's ligament to terminate in the external iliac 

 plexus. 



The Epigastric Absorbents are derived from the inferior an- 

 terior parietes of the abdomen, along the region of distribution 

 of the epigastric artery. Their trunks coalesce into larger ones, 

 and descend along this artery to end in the external iliac plexus, 

 near the crural arch. 



Tb.e Lumbar Absorbents arise from the muscles of the loins, 

 from the posterior par?, of those of the abdomen, and from the 

 spinal cavity. Their trunks correspond with the lumbar arte- 

 ries, and passing beneath the psoas magnus muscle towards the 

 gpine, they terminate in the lumbar glands.
