and if the animal be weak tonics should be administered, especially 
arsenic and iron. 
Local. — With regard to the local treatment the parts should be 
washed with soft soap and tepid water, dried and dusted over with 
a powder of oxide of zinc i, starch 4 parts, or boracic acid and zinc 
oxide 2 parts of each, starch 6. Where the ears are very bad 
resembling an immense sore, it is desirable to have the neck washed 
morning and evening with disinfectants and afterwards smeared 
with carbolic oil or some such preparation, so that the ears may 
come in contact with a clean surface. If there are scabs the crusts 
should be soaked well with sweet oil or glycerine and when soft 
removed by washing. The resulting raw surfaces should be cleansed 
with weak carbolic lotion i — 80, phenyle i — 80, permanganate of 
potash 8 grs. to the pint, after which dry dusting powders may 
be employed. If flies are troublesome, a little iodoform or euca- 
lyptus oil may be added, the parts may be dressed with oxide of zinc 
ointment ; boracic acid ointment ; dikamali ointment ; acetate of lead 
ointment— 15 grs, to i oz. lard; or white precipitate ointment, 
ammoniated mercury i dr., lard i oz., or acetate of lead i dr., 
glycerine i oz., water i pint. Two or three drachms of powdered 
borax may be substituted for the lead. In cases where there is much 
weeping, the parts after being washed may be painted over once 
with a solution of nitrate of silver 4 per cent. This is often very 
effective. 
The eyes when affected must be treated as laid down under 
inflammation of the cornea. In one case sloughing of portions of the 
tail and ears were superadded to the above, but whether dependent 
or independent of this affection it is very difficult to say. 
Boils. 
Boils are frequently met with in this animal confined to no parti- 
cular part of the body, but perhaps more often seen on the front 
of face or quarters, inside of thighs and under the belly, but 
they may be distributed all over the body. They may be either 
boils which proceed to suppuration, or what are known as blind 
boils,'' that is, they do not go on to the formation of matter and 
may disappear with or without treatment. 
Causes. — Derangement of the digestive organs especially the 
liver and depravity of blood from any cause. Intelligent 
mahouts say they may arise from the too free use of mercury." —

under the section on parasitic disorders due to flies.
