TREATMENT OF FISTULOUS TRACTS.

Should what I offer prove a benefit to any, or aid in the 
least in the treatment of these troubles, I will feel more than 
repaid and that my efforts have been not entirely in vain. 
Case i.— In January, 1891, my attention was called to a 
well developed poll-evil in a bay mare, fifteen years old, in 
fair condition, weight about ten hundred pounds, and used 
for driving purposes. 
For several weeks there had been a free discharge from 
either side. The openings were enlarged with the bistoury 
and this was all the case called for in tlie way of operating. 
After evacuating the cavity of pus with carbolized water, 
a solution of alcohol and bichloride (ten grains of the latter to 
the ounce of the former) was injected and retained in cavity 
for twenty-four hours by pledgets of absorbent cotton. At 
the expiration of that time they were removed and the wound 
dressed antiseptically. This solution was injected twice after¬

not being used. The case recovered in six weeks with no 
other attention than injecting every second and sometimes 
every third day, one of the following : a weak solution of 
potassium permanganate, zinc sulphate, or a watery solution 
of iodine and pot. iodide. Externally the parts were kept 
well cleansed and lubricated with carb. cosmoline. 
I took particular care to guard against flushing or washing 
out the sore with water, none being employed except that 
in the solutions and that used on the first day of treatment. 
No after-complications arose and the animal has been in good 
condition since. 
Case 2 —Fistulous withers in a black mare. The animal 
was in good health, of medium weight and had been used for 
farm purposes. 
August 1st.—I made free incisions and used nitrate of silver 
solution in the cavity. The owner took the mare home, a 
distance of six miles, and for seven weeks treated with white 
lotion and copper sulphate in solution. The animal was 
brought to me again and examination proved results unsatis¬ 
factory. 
At this time, Sept. 26th, the incision had nearly closed, but
