DISEASES AND INJURIES OF THE EAR 91 



Treatment. 



Rub with boracic acid ointment, but in the case 

 of long-haired cats it is better to dress with a non- 

 greasy application. Therefore the following is 

 suitable : 



ft Oil of tar . . . 2 drachms. 



Bismuth .... 4 



Methylated spirit . . 4 ounces. 



Castor oil ... 2 drachms. 



Mix and apply daily. 



Morbid Growths in the Auditory Passage. 



Not uncommonly warty excrescences grow 

 within the middle ear, and sometimes completely 

 occlude the passage. 



Advanced cases of canker necessarily cause a 

 great deal of irritation, and nature seems to make 

 provision by the formation of new growths in the 

 ear, in order to strengthen the lining membrane, 

 though, of course, this is abnormal and destroys 

 the hearing either partially or wholly. 



Professional skill is needed for their removal. 



Accumulation of Waxy Material. 

 The normal waxy secretion accumulates to an 

 excessive amount, and blocks up the passage. The 

 best plan is to pour in half a teaspoonful of warmed 

 glycerine daily.
