THE LYMPHATIC SYSTEM 



Within the Malpighian corpuscle the artery gives off capillary 

 twigs which pass radially to the adjacent spleen pulp, and there 

 enter the small veins. At the circumference they are in close 

 relation with the splenic ellipsoids, which are formed by minute 

 condensations of the splenic reticulum (Schafer). 



Within the Malpighian corpuscle also, or in the adjacent splenic 

 pulp, the small artery breaks into a minute brush of terminal ves-

sels, the penicilli of Ruysch. The ultimate destiny of these vessels 

 is still in doubt, some observers claiming that they open free into 

 the reticular meshes of the spleen pulp, others that they form a 

 system of closed capillaries within the pulp, by which the blood 

 is transferred directly to the veins.
