DISEASES OF THE EAR. 121 



R Bromo-Chlorali 



Tr. Opii aa 3 i 



Aquae 3 vi 



Ft. Mist. Sig. Drop in the ear. 

 This preparation can be alternated with the first one advised, using one, 

 then two or three hours later the other. 



When there is much discharge the powdered boracic acid dropped in the 

 ear is productive of good results. 



If canker is confined to the outer cavity and flap of the ear, accessible to 

 direct application, stronger remedies can be safely used. If the parts are 

 simply red and inflamed, cleanliness and applications of the following 

 will suffice.— 



R Acid Carbolic! 3* 

 Glycerinae Ji 



Ft. Mist. Sig. Paint the affected part several times daily after sponging. 



If an ulceration exists, it will be well to cauterize with the stick nitrate 

 of silver or concentrated carbolic acid, after which the paint can be 

 applied. 



While recognizing the fact that in a majority of cases of canker there is 

 some associate general affection which demands treatment, the need to 

 follow the stereotyped rule of first giving a cathartic is not appreciated 

 by the writer, unless the conditions are favorable and there is good and 

 sufficient reason for it. 



If the animal is overfed and plethoric, or if some fever attends, then 

 certainly a purgative is demanded; but if on the other hand he is debilita- 

 ted by a long illness, or some rapidly exhausting disease, it were much 

 better withheld. 



In debility, iron, quinine, or cod liver oil with a generous and nutritious 

 diet is indicated. 



Whatever disease may be associated, its treatment is not influenced by 

 the presence of canker, but constitutional remedies are to be administered 

 as the need is manifested.
