RESULTS OF W0UND3. 



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 wbich 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 knowu 

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

 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, 

 phlef^monous, bilious, cedematous, erratic, and periodic ; but 

 in the horse the cedematous 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 unascertained alteratioa 

 in the blood, induced by the Streptococcus erysipelatosus. 



OJDEMATOUS ERYSIPELAS. 



This is the most common form of traumatic erysipelas met
