RESULTS OF WOUNDS. 



ERYSIPELAS, SIMPLE AND PHLEGMONOUS SYMPTOMS AND TREATMENT 



TETANUS — IDIOPATHIC AND TRAUMATIC VARIOUS FORMS OF 



SYMPTOMS — PATHOLOGY TREATMENT. 



The various forms of wounds having been described, the dis- 

 eases which occasionally follow them may here with propriety 

 be considered. These are Erysipelas and Tetanus. 



ERYSIPELAS. 



Although the redness of skin, which is one of the charac- 

 teristics of this disease in man, so that it is popularly known 

 as " the rose," and " St. Anthony's fire," is absent, or at least 

 cannot be perceived, in the lower animals, owing to the thick- 

 ness of the epidermis and colour of the hair, yet it is essentially 

 the same, arises from similar causes, and requires a correspond- 

 ing treatment. The disease in man is divided into simple, 

 phlegmonous, bilious, oedematous, erratic, and periodic ; but 

 in the horse the oedematous and phlegmonous are the only 

 forms originating traumatically, and a bilious, periodic form, 

 simulating what has been already described as lymphangitis 

 or inflammatory oedema. 



Erysipelas may be defined to be inflammation of the skin 

 and subcutaneous areolar tissue, characterised by a diffused 

 swelling of the parts affected, which has a remarkable tendency 

 to spread, and is dependent upon some alteration in the blood, 

 induced by the Streptococcus erysipelatosits. 



OEDEMATOUS ERYSIPELAS. 



This is the most common form of traumatic erysipelas met
