6. The hepatic artery, which is not only distributed to the, liver, but nl-o turni-h'- a 

 branch for the gall-bladder, and a duo Yual artery breaking up into two bninches : the 

 posterior branch forming with the first artery of the small intestine an arching ;i 

 mosis ; the anterior communicating with the superior artery of the omasum and aboinusum. 

 This hepatic artery always originates between the trunk common to the splenic artery 

 and the superior branch of the rumen, and that which gives rise to the superior branch 

 of the same viscus and the artery of the relicnlum. 



The terminal bninches of the cceliac artery comport themselves as follows : 

 1. The superior artery of the omasum and abomttsum passes successively to the great 

 cui vature of the first of these reservoirs, and to the concave curvature of the second ; then 

 it goes beyond the pylorus to unite with the duodenal branch of the hepatic artery l>v 

 inosculation (Fig. 273, 6).

2. The inferior artery of the omasum 'and alomamm, on the contrary, passes at first 

 over the small curvature of the omnsum, afterwards the great curvature of the almniasuin, 

 and disappears in the omentum, to which on its course it furnishes a great number of 

 branches (Fig. 273, 7). 



In small Ruminants, the distribution of the arteries of the ccoliac trunk presents 

 some modifications. We will cite the principal, which belong to the mode of origin of 

 the two branches destined for the reticiilum : tiies- branches form two particular 

 vessels which arise singly from the eooliac trunk ; the inferior artery at the same point as 

 the superior artery of the rumen, the superior towards the terminal bifurcation of the 

 trunk. 



Great metenlerin artery. Its origin approaches very closely that of thecoaliac trunk. 

 After a course of from 6 to 8 inches, it divides into two branches an anterior and a
