CHROMIC ACID.

greatly emaciated and had the largest fistulous tumefaction I 
ever saw. In fact, this tumefaction was so large I would fear 
the loss of your respect for my truthfulness should I give its 
dimensions. I recommended six weeks’ rest with good care 
and feed and 30 grains of sulphate quin, with tr. fe. chlor. three 
times a day ; as I told the owner, a to get something to work 
on besides the fistula.” 
This beast had been treated (?) one year by a “ Thistlo ” 
horse doctor and pronounced incurable previous to my services. 
After the horse had recuperated sufficiently I began the treat¬ 
ment as follows : With a silver director I probed the sinuses, 
laid them open with the bistoury, made a swab by wrapping 
white muslin projecting over the end of a stick, dipped it in 
the solution of chromic acid, 1 part and aqua 500 parts, and 
with this entered the fissures and sinuses, applying freely the 
diluted acid to the diseased parts. 
After a few days the tissues parted, the diseased from the 
healthy part, leaving a clean, granulating surface, which, with 
the aid of the “ white lotion,” soon healed without a scar or 
blemish. That I may not be misunderstood I will say that it 
took about eight weeks to effect this cure, and some new 
sinuses were treated in the aforesaid manner as they made 
their appearance from time to time. 
Case II. A bay gelding, eight years old, used as a dray 
horse, acquired a sore on his back from the backhand of the 
harness chafing it. 
This sore refused to heal for the remedies generally used 
for such abrasions; then my attention was called to it and I 
found a red, spongy, warty, quick-growing tumor which I could 
not give any special classification at the time, and even now 
would hardly dare to try to classify it. 
To this tumor, after breaking all the tender substance down 
with my thumb nail, I applied freely the chromic acid solution 
as given above and the result was a speedy, permanent cure 
without any further treatment whatever. 
I might mention numbers of these trivial cases, but
