MOTION OF THE HEART AND BLOOD 



the upper part of the splenic branch leading to the 

 pancreas arise the posterior coronary, gastric, and 

 gastroepiploic veins, all of which are spread in many 

 branches on the stomach, like the mesenteries on 

 the intestines. Likewise, into the lower part of this 

 splenic vessel empty the hemorrhoidal veins from 

 the colon and rectum. Through both these venous 

 systems returning blood is poured into the splenic 

 branch, carrying with it from the stomach a crude 

 watery juice not completely chylified, and from 

 the feces a thick earthy material. Both these are 

 appropriately tempered by natural mixture, al- 

 though difficultly concocted alone, because of op- 

 posite defects. Then, diluted by a large amount 

 of warm blood flowing through the spleen from 

 its large artery, the mixture enters the portal of 

 the liver in a better state of preparation. The de- 

 fects of either extreme are made up and compensated 

 by this arrangement of the veins.
