from entering the water, absolute cleanliness of the ears, 
with repeated application of suitable remedies, and; 
meanwhile, securing the ears from damage by flapping 
by means of a suitable cap or bandage. Diligent atten- 
tion only will be rewarded by improvement and cure. 
The best applications are the ointments of carbonate or 
oxide.of zinc, applied once or even twice a day, after 
the ears have been carefully syringed, or “‘ mopped out” 
by means of a small piece of sponge on the end of a 
stick, “ Sanitas” Fluid forming an admirable agent for 
purifying and stimulating the parts to healthy action. 
In simple Ofi#7s a diligent use of the Fluid, with a dose 
of laxative medicine will be probably all that is required. 
The fever of Internal Canker is also beneficially treated 
by means of a laxative, as the castor-oil mixture, or, if 
unusually severe, a'saline cathartic may be called for. 
External Canker is the term used to denote the 
diseased changes which take place on the lower margins 
of the ear-flaps. As already pointed out, the affected 
animal shakes his head violently, by which the ends of 
the ears are caused to strike the sides of the face and 
top of the head, or the collar, if such is worn, with 
violence. They are bruised and inflamed; shortly 
swelling, thickening, and ulcerative changes follow, and 
the disease from the first assumes an obstinate or chronic 
character. As thesé conditions arise from the irritation 
due to the existence of Internal Canker, that disease 
must receive appropriate attention. The flaps of the 
ears in recent cases may be first cleansed from all 
accumulations of dried pus, dirt, &c., and afterwards 
covered with an application of ‘“Sanitas ” jelly, calamine, 
or oxide of zinc ointment. Oldei-standing cases may 
call for the application of the nitrate of silver to stimu- 
late healthy healing power, the ears being secured from. 
injury by means of a cap properly fitted and secured 
over the head. 
Abscess of the Ear-Flap, or Blood Abscess, is 
large, painful swelling, of sudden appearance, due to 
bruising by violent shaking of the head. The tumour is 
tense, but is found to contain a yielding substance within,
