to the semilunar ganglion ; from the ganglion in the tenth intercostal space another 

 branch is given off, it soon joins the second, principally by cellular tissue, but does 

 not appear to have much communication with it ; the third is soon joined by a fourth 

 from the eleventh intercostal space ; it communicates with the great splanchnic and 

 then passes through the diaphragm ; these branches coalesce into an expansion which 

 is thin at the upper part and thicker and narrower below ; it is very much connected 

 with the renal capsule ; it sends branches on the diaphragm expanded into a broad 

 and thin semilunar ganglion ; from its lower part two large branches are sent to the 

 kidney. The semilunar ganglion, which is similar in structure to that of the pig, 

 communicates on each side with the anterior cord of the par vagum, and on the left 

 with small branches sent from the posterior cord of the par vagum ; it sends branches 

 with the divisions of the coeliac artery, which has a long trunk, and, with the splenic 

 artery, to the pancreas, spleen, and first or cuticular stomach ; with the hepatic to the 

 liver; and with a branch of the hepatic to the fourth stomach, or second duodenal 

 pouch, which meets a branch of the superior mesenteric supplying the fifth stomach, 

 or third duodenal pouch : this branch of the superior mesenteric also sends a branch 

 to the liver ; the rest of the coeliac artery, which may be called coronary and is its 

 principal part, passes chiefly to the second or villous stomach, but also gives some 

 branches to the third stomach, or first duodenal pouch, and to the first or cuticular 

 stomach ; this also receives branches from the phrenic and from the splenic already 

 mentioned, and on the branches of the coeliac artery, branches from the semilunar 

 ganglia are sent to the viscera. The principal portion of the branches from the 

 semilunar ganglia passes with the superior mesenteric artery, and separates to be 

 conducted on branches of this to supply the large mesenteric glands and the intestines. 

 Besides the numerous branches sent along the mesenteric artery to the upper portion 

 of the intestines, others proceed from the inferior part of the semilunar ganglia, which 

 pass rather more than an inch to an oval ganglion of considerable size, placed in the 

 mesentery ; branches of this communicate on branches of the mesenteric artery as 

 they. pass to the upper portion of the intestines; the rest pass in the inferior part of 

 the mesentery, and are joined by others from the inferior part of the semilunar ganglia,
