FISTULOUS NOSE. 
Wounds sometimes produce ulcers in the back part of the nose, perhaps 
inducing ulceration of the bones which discharges a thin, unhealthy, pus- 
like fluid, such ulcers being of a fistulous character. 
TREATMENT.—Apply to the fistula a solution of carbolic acid, ten drops 
to an ounce of glycerine. Wash well with soap and water. The following 
formula will be useful if the fistula does not heal but remains unhealthy:. 
Hydrastia, 20 grains. 
Todoform, Io grains. 
Sugar, 1% ounce. 
Pulverize together in a mortar until they are thoroughly mixed; then 
apply to the fistula once a day, blowing it trom a quill. 
POLL EVIL. 
Poll evil results from some blow on the top of the head, or from a 
coarse, heavy head-collar chafing the part. 
Symptoms.—Hanging head, the horse being unwilling to be handled 
about the ears; painful swelling just back of the ears on the top of the head, 
at first hard, then growing soft, of the nature of an abscess, gradually 
‘coming to a head, bursting, and discharging matter, which is sometimes 
healthy, in other cases, when the liga- 
ments and bones are involved, unhealthy 
and offensive. The probe will detect 
a single cavity, without canals, or canals 
passing in different directions, perhaps 
extending to the bone. 
TREATMENT.—This disease is very 
difficult of treatment except in the 
earliest stages, when it may be checked 
by removing the cause and applying

matter should be prevented if possible. When this can not be done, cut 
open the hard, painful swelling (¢f you area skillful operator), and apply 
lint saturated in equal parts of glycerine, calendula and water, oil-silk being 
put on then, and a linen hood with openings for the ear being fastened on 
with tapes around the jaw and neck. Moisten the linen three times daily 
with the lotion. Should the tumor become soft and mobile, a surgeon 
should at once open it, in such a way, if possible, as to allow the matter to
