ON THE PATHOLOGICAL MORPHOLOGY OF SOME ANIMAL FLUIDS. 269 



3. From the dilated intermediate and capillary vessels. 



4 ( recently formed soft fibrils. 



5. globules of pus, of inflammation. 



6. smaller molecules, here and there dispersed. 



7. small quantity of serum, with which we see the tex- 

 tures kept moist. 



The exudation is changed in direct relation with the obliteration and 

 dilatation of the intermediate and capillary vessels ; and in the same 

 manner as the obliteration proceeds from the centre of the inflammation 

 to the periphery, so the whole process of inflammation is propagated 

 from the centre (focus) towards the periphery. But if the cause excit* 

 ing the inflammation, is more intense, it acts by destroying the normal 

 texture ; globules, mixed with serum, then form a peculiar fluid, named 

 pus, in the limits of the injured organs, which flows together from its 

 different parts, and either remains for a long time enclosed in a pathologi- 

 cal cavity (abscess), or flows out from a pathological surface (wound) ; 

 but the pathological fibrils, which, creeping over, constitute the granu- 

 lations for the new intermediate vessels, are fixed to the parietes, until 

 the pathological surface (wound) shall have ceased to exist. Hence 

 the normal inflammatory process everywhere offers to us the same pro- 

 ducts, which differ as to the quantity and external form, but not as to 

 quality and internal composition; for the inflammatory tumour and 

 boundary of the adhesive inflammation is constructed of the same con- 

 stituent parts as the true inflammatory boundary of suppurative inflam- 

 mation. But in considering a pure, recent, incised wound, where all the 

 parts are not only organically disturbed, but their texture and cohesion 

 (the causes of all organic formations), in part of the incision are des- 

 troyed and removed, the suppurative inflammation will only be excited 

 when the pathological surface shall not have been brought together by 

 the aid of a suture or ligature ; but if anything shall have brought the 

 pathological surface of the lips of the wound in contact, then the adhe- 

 sive inflammation will certainly be produced. 



In the reported case, the mischievous power and the same lesion then 

 may produce suppurative inflammation, if the pathological surface con- 

 tinue exposed, and the adhesive inflammation, if you shall have brought 

 it together. 



In a pure, suppurating, fistulous wound, pus is generated by the sup- 

 purative inflammation, as long as the pathological surface continues 

 exposed or open ; but, being brought together, (for example, by proper 

 compression), the adhesive inflammation arises, and pus is no longer 

 formed.
