still large enough to admit the nozzle of a fair sized syringe. 
Did not use the knife this time. Injected the alcohol solution 
the same day, and the two following days hydrogen peroxide. 
Used the alcohol solution again on the 29th. and followed 
daily with the hydrogen peroxide. October 7th the case had 
recovered. 
Case 3 —Poll-evil in gray mare, four years old and weigh¬ 
ing nearly twelve hundred pounds. Laid open on each side 
and evacuated of pus, followed by a ten per cent, solution of 
pepsin injected and retained by means of closing wounds with 
cotton. The animal being five miles from town, 1 gave in¬ 
structions for removal of cotton next day and daily treatment 
with white lotion. 
Five weeks later I saw the patient and found results very 
unsatisfactory. 
I requested that the animal be brought to town, which was 
done some eight or ten days later, when I again tried the 
pepsin solution, injecting several times during a period of two 
weeks with same result; then commenced treating with the 
bichloride solution. This was injected daily for five days; 
at the expiration of that time healthy granulations were ap¬ 
parently set up. Hydrogen peroxide was alternated with 
white lotion daily at first, and later every second, and still 
later every third day. 
During the last two weeks zinc ointment was applied ex¬ 
ternally. 
Seven weeks from the date of using the alcohol solution 
the patient had successfully recovered. 
Case 4.—Fistulous sore in roan horse, of twelve weeks 
duration; a result of injury inflicted by some sharp-pointed 
instrument, which penetrated the tissues inward and down¬ 
ward immediately beneath, or inferior to, the wing of the 
atlas. The direction of the wound prevented the free exit of 
pus, and to this fact I ascribed the cause of the formation of 
the pus-secreting walls composing the fistula. 
For two weeks I used hydrogen peroxide with little en¬ 
couragement ; then used alcohol solution four times and fol¬ 
lowed with the peroxide. The last week zinc sulphate was
