EABi, CAITEEB OF.— This disease is usually divided into 

 " internal canker " and " external canker." Internal canker consists 

 of inflammation of the lining membrane of the passage to the 

 ear, which runs on to ulceration and sup^- .:-ation ; when of long 

 standing a blackish offensive discharge takes place and accumulates 

 in the passage, and on examination the inte'ior of the ear will be 

 found to be red and inflamed. The dog ihus suffering may be 

 observed frequently scratching hia ear with his paw, holding iiia head 

 on one side and giving it a violent shake, as though to empty some- 

 thing out of the ear ; and the pain and irritation arising from the 

 disease cause him to rub and shake his head constantly and violently, 

 whereby the flaps of the ears get bruised, ulcerations form, and the 

 tips become obstinately sore. The inflammation existing in the 

 interior lining membrane extends itself to the outside through the 

 constant shaking and scratching, and external canker is also estab- 

 lislied. It is not an uncommon belief that canker of the ear is 

 confined to water dogs. This error arises no doubt from the fact 

 that water spaniels and others of that class, from theii exposure, 

 are most likely to get water lodged in their ears, the shaking and 

 pawing to get rid of which frequently sets up the inflammation, 

 ending in canker. The tears and scratches received from briars and 

 thorns in working close coverts, if not attended to, may also set up 

 external canker of the ear. The insinuation of wet and dirt, and 

 the accumulation of hardened wax in the ear-passage, are no doubt 

 causes, and axe especially likely to produce baneful results where a
