(Edema Glottidis. 163 



The local pasty swelling and the absence of any false mem- 

 brane sufiBce usually to distinguish it from croup which it so 

 closely resembles in the suddenness of its onset, and the violence 

 of its manifestations. 



The less urgent cases may be treated by application of cold water 

 or ice to the throat, and the injection of solutions of chloride of 

 iron or alum into the fauces. Or the throat may be painted with 

 tincture of iodine and rubbed with the palm to favor distribution 

 and absorption of the exudate. In dogs the mouth may be opened 

 widely and the dropsical membrane pricked at intervals to drain 

 off the liquid. In the most acute cases the prompt adoption of 

 tracheotomy is the only means of saving life.
