THE ANGIOLOGY OF THE STOMACHS OF 
RUMINANTS. 
By Professor GELLE, of the Royal Veterinary School of Toulouse. 
The posterior aorta presents no other sensible difference in the 
ox, compared with its course in the horse, than in the vessels which 
are determined to the stomachs : thus the celiac artery, a much 
larger vessel in cattle than in the horse, is divided at first only into 
two principal branches ; first, the hepatic, which takes the same 
course as in the horse, and all whose ramifications are confined to 
the liver ; second, the gastric, which afterwards furnishes the 
splenic. The splenic artery itself differs from that of the horse ; for, 
after the space of an inch, it is divided into two branches, the an- 
terior of which proceeds forward, and towards the left, arrives at the 
scissure of the spleen, and expends itself in that body without con- 
tributing any vessels to the paunch. The other, situated posteri- 
orly, and of larger size, and destined for the rumen, takes a direc- 
tion posteriorly— follows the superior scissure, and then takes the 
posterior one — enters between the two lobes of that stomach, and 
arrives at last at its inferior surface, where it bifurcates, following 
the scissures which form the compartments of the rumen. 
This artery furnishes some lateral branches in its passage, which 
distribute themselves on all the posterior and inferior parts of that 
viscus. The gastric branch of the celiac, or rather the gastric ar- 
tery, is also divided into two principal branches ; first, the anterior 
one, which follows the superior canal, reaches the anterior medias- 
tinum, gives different branches to the anterior part of the paunch, 
and has frequent anastomoses with the vessels that come from the 
posterior branch of the splenic artery ; second, the posterior one, 
which gives numerous branches to the reticulum, the maniplus, 
and the abomasum : the veins follow an analogous direction, in 
order to pour themselves into the splenic branch of the vena porta. 
By this arrangement it is seen that the posterior branch of the 
splenic artery in the ruminants replaces those vessels which, in the 
horse, go from the splenic artery to the great curvature of the 
stomach. 
In the young sucking animal, and in whom, consequently, the 
paunch discharges no function (if we may so say), the vessels of 
the abomasum are most developed and receive most blood ; but this 
vascularity gradually changes, and in proportion as the animal uses 
aliment of greater consistence, and susceptible of undergoing the 
process of rumination. In the adult animal, the distribution of 
these numerous arterial ramifications is disposed in such a way 
that, all other things being the same, the paunch receives the least 
blood, the reticulum a little more, and the abomasum is the most
