points of the stroma at tolerably uniform intervals. This stroma 

 can only be demonstrated by carefully pencilling out a fine 

 section of o-ranulation-tissue hardened in alcohol. 



This arrano^ement constitutes of itself a structure of a liiMicr 

 order, comparable in some degree to the connective-tissue stroma 

 of the intestinal mucous membrane ; and the analogy is carried 

 farther by the occurrence of certain spheroidal bodies which I 

 must pronounce to be newly-developed lymphatic follicles (fig. 

 40). These lie in the midst of the parenchyma, equidistant on 

 every side from the greater vessels. AVe can readily convince 

 ourselves, by examining very fine sections which have been

pencilled out, that these round nodules consist mainly of a very 

 delicate reticulum in which minute lymph-corpuscles are em- 

 bedded. The lymph-corpuscles are more firmly attached to the 

 reticulum towards the periphery of the nodules than in their 

 centre ; so that we usually have a border-zone, which it is difficult 

 to clear up. Beyond this we find a zone, traversed by stellate 

 corpuscles of considerable size ; so that if we could only prove 

 that these structures were in communication with the lymphatic 

 vessels, the evidence in favour of their being true lymphatic 

 follicles would be complete. I may remind the reader that this 

 communication still remains to be proved in the case of the 

 tonsillar follicles as well.
