covering with a thin piece of lint soaked in the carbolic solution, 

 over which place a second and dry piece. Confine all to the eai 

 by means of collodion, sealing it to the ear around the edges. 

 Remove a^ *.he end of twenty-four hours ; when, if the ulcer have 

 a healthy appearance, wash well with carbolic acid solution, and 

 apply lint as before ; but let the collodion cover the whole of the 

 material as well as the edges, so as to shut out all air ; let remain 

 for four or five days, when it may be redressed in the same man- 

 ner. 



If this proves inefficient, the ulcer remaining unhealthy and 

 spreading, the ear also becoming hard and indurated for some dis- 

 tance around the ulcer, we may fear that the trouble is maligfnant. 

 Apply a solution of chromic acid, ten grains to the ounce of water 

 daily until the foul portions of the ulcer are eaten away, and it has 

 a healthy appearance, when bring the edges as closely together as 

 possible, and dress as before. Strong glacial acetic acid will an- 

 swer the purpose where the chromic cannot be obtained. Where 

 the swelling is great, a hypodermic syringe should be used, and five 

 drops of common acetic acid injected into the hardened substance 

 upon one, two, or three occasions as maybe required to thoroughly 

 permeate the tumor. This should only be used when it is certain 

 the disease is malignant. Such treatment, if properly carried on, 

 will usually dispose of maUgnant growths. 



A cap should be worn by the dog, to confine the ears, and to 

 avoid dressings being displaced while under treatment. 



For troubles of the inner ear, let it be carefully washed out with 

 tepid water and castile soap by means of a smaU syringe. Now 

 look carefully for any foreign substance, as insects, dirt, stones, 

 beards of wheat, or bits of grasses, that may be causing the trouble. 

 If you can procure a silvered ear speculum, and learn to use it, all 

 the better. If you find no cause, you may very properly conclude 

 that it is a case of simple abscess, when you may pour a few drops 

 of glycerine, in which a little sulphate of zinc and morphine have 

 been dissolved, into the ear, afterwards plugging the orifice with 

 cotton. Change the dressing every twenty- four hours, washing 

 out the ear with warm water and castile soap. Be careful not to 

 force too powerful a stream of water into the ear, or you may do 

 injury. During these washings you may be surprised by a sudden
