apply boric acid (3ii in alcohol (3x) and ether (^iiss). Salicylic

In Horses; rarely in Cattle and Dogs. 



Due to left-sided paralysis of the larynx, from toxemia of acute 

 infections ; also to thickening of the mucous membrane, obstructions, 

 stenoses, and new growths in the upper air passages. Paralysis of 

 the larynx is only relieved by arytenectomy. Following acute in- 

 flammation of the throat, apply a fly blister over the larynx, 646, 

 or better, red mercuric iodide, 310. Give internally potassium iodide, 

 349, thrice daily for some time. The local injection of strychnine,

 set of paralysis. Arsenic internally may aid the action of the 

 iodide in promoting resolution of thickened mucous membrane, 236.
