 suppuration and ulceration. 



Resolution. If an inflammation, slight in character and with 

 only a moderate exudation, subsides and is followed by a rapid 

 liquefaction of the cells and fibrinous coagula and a reabsorption 

 of the exudate, so as to leave the part in its primary -healthy con- 

 dition structurally and functionally, it is said to have terminated 

 by ' ' resolution. ' ' If this occurs with extraordinary rapidity it is 

 said to have ended by ' ' delitescence. ' ' This is not always an unal- 

 loyed good, as often in delitescence, coagula and infecting material 

 may be carried on by the circulation, to block the next set of 

 capillaries in its course and set up new centres of inflammation. 

 This is one form of ' ' metastasis' ' though a more definite metasta- 

 sis is in rheumatism where the disease attacks one joint to-day 

 and a distant one to-morrow. 



Inflammatory New Formations. Of the growths in lymph 

 there are two principal kinds : first, t/ie plastic, fibrinous, granu- 

 lar qt molecular ; and second, the aplastic or corpuscular. The 

 first form tends to develop into new structure, the second to dis- 

 integrate and decay. The tendency to one or other form depends 

 largely on the strength or weakness of the sy-stem's health, on the 

 deficiency or excess of corpuscles in the exuded fluid, and on the 

 distance of the latter from living tissues and blood supply. Much 

 also depends on the predisposition of the genus, the tendency to 

 suppuration in lymph being in a descending series from horse, ass,, 

 and mule, through ox and sheep, to dog, pig, and finally, the 

 bird, in which latter suppuration is quite exceptional. 



Suppuration. In inflammations of a high type, in those oc- 

 curring on the skin or mucous membranes in which there is an 

 extraordinary increase of nuclei and embryonal cells, and in lymph 

 thrown out in excess at one point, so that its central parts are far 

 from vascular tissue and nourishment, the cell elements undergo 

 a rapid increase and degradation into pus-corpuscles, and its solid- 

 ified intercellular lymph undergoes granular decay and liquefaction 

 into pus. 



While the above conditions are favorable to the formation of 

 pus, the process of suppuration must now be recognized as an in- 

 fective process due to the propogation of bacteria (mainly chain 

 forms — Streptococcus pyogenes — cluster groups — Staphylococcus py-
