TERMINATIONS OF INFLAMMATION. 27 



nonnil fluid condition, as it occurs in ordinary serum w'lien 

 blood is drawTi from the body before the fibrine has coagulated. 



2d. The exudation is more complete, the exuded lymph is 

 consolidated, or even transformed into a low form of fibrous 

 tissue, surrounded by and soaked in much serosity. At this 

 point its organization is arrested, the contents of the cells con- 

 verted into fatty granules, the cell walls break down, the granules 

 escape into the surrounding fluid (serosity), forming a fluid resem- 

 bling chyle — called pathological milk by Virchow. In this condi- 

 tion it is absorbed into the circulation, and after undergoing other 

 transformations whilst mixed with the blood — converted into 

 urea, hippurates, ammonia, carbonic acid, &c, — is finally ejected 

 from the system by the excretory organs, leaving the inflamed 

 part in its original condition, or perhaps slightly altered. 



The termination which has been called " Adhesion " is another 

 method by which the exudate is disposed of, and presents a more 

 complete and higher organization of the lymph than the former. 

 In this process the cells, instead of imdergoing fatty degenera- 

 tion, become developed into a form of fibrous tissue, which in 

 the course of time becomes vascular by the formation of new 

 blood-vessels within its substance; and whilst organization is 

 going on in the tissue, the surrounding serum is absorbed, 

 leaving the new formation as part of the economy, remain- 

 ing 80, as in the adhesions of pleuritis, &c., throughout the 

 animal's life. 



The formation of the new blood-vessels is very interesting, 

 and is supposed to be effected as follows : — Coincident with the 

 Btructural development of the cells and intermediate substance 

 into connective tissue, new blood-vessels are formed by outgrowthi 

 from the walls of the original vessels of the surrounding paits. 

 These outgrowths first appear as slight pouches on several 

 original vessels ; these pouches or dilatations first present them- 

 selves on one point of a vessel, then on another, as if its 

 walls yielded a little; they gradually extend themselves as' 

 blind canals from the original vessels, directing their course 

 towards the edge or surface of the new material, and are 

 crowded with blood globules, which are pushed into them from 

 the main stream. Still extending, they converge and meet ; 

 the partition wall that is at first formed by the meeting of their 

 <5losed ends clears away, and a perfect arched tube is thus made.
