162 SPECIAL EQUINE THERAPY 



ment of parturient paresis in cows, must be at hand. By 

 means of rubber tubing and a hypodermic needle the 

 oxygen is forced freely into various parts of the tume- 

 faction. 



Other practitioners claim good results from incising 

 the active region of the. swelling freely, and then packing 

 it with gauze or wads of cotton previously saturated with 

 hydrogen peroxid. All the cases that I saw were treated 

 by simply cutting freely into the active area of the tume- 

 faction and liberal irrigation with peroxid of hydrogen. 

 AU died. Cases reported as recovering are said to make 

 a slow final recovery. Usually the gangrenous center of 

 the tumefaction sloughs out, leaving a difficult wound to 

 heal. 



In future eases of malignant edema in my practice I 

 shall resort to treatment similar to that used in poisonous 

 snake bite, namely, complete extirpation of the active 

 area followed by the application of crystals or a saturated 

 solution of permanganate of potassium. The internal 

 treatment should consist of supportives.
