Local lesions consist of inflammatory processes the 

 predominant character of which depends principally 

 on the special pathogenic property of the microbes 

 contained in the wound; these processes may be es- 

 sentially exudative ; inflammatory oedemas, erysipelas; or 

 suppurative : superficial suppuration, abscess, phlegmon; 

 or hypertrophic : actinomycomata, botryomycomata , an- 

 atomical tubercles: or, finally, gangrenous: traumatic 

 gangrene, diphtheria, hospital gangreiie. The dominant 

 character of these inflammations depends principally, 

 but not exclusively, on the special nature of the germs 

 distributed upon the wounds; in reality, the reaction- 

 ary powers of the tissues have also their influence 

 here, and a given germ, the streptococcus of erysipe- 

 las for example, will occasion sometimes a simple 

 dermatitis with interstitial and superficial exudation 

 under the form of vesicles, phlyctenae (erysipelas), 

 sometimes it will determine, in addition, a deep seated 

 suppuration (phlegmonous erysipelas), and even ne- 

 crosis of the inflamed tissues (gangrenous erysipelas). 



Remote lesions manifest themselves in the organs 

 in direct or vascular continuity with the tissues orig- 

 inally attacked. Hence, we see peritonitis occur 

 consecutive to changes of a microbic nature located 

 in the abdominal viscera: wounds of the intestine, 

 of the uterus, metritis, etc. In respect to vascular 

 continuity, this involves alterations of the correspond- 

 ing lymphatics and blood vessels {lymphangitis, adenitis, 

 phlebitis, endocarditis, thrombic and embolic lesions). 



Finally, as general troubles, we have pycemia and 

 surgical septiccemias.
