MALIGNANT CORONITIS. 
277 
Of these methods the first five are-, of course, useless, except 
in cases of very slight severity, and only affected very super¬ 
ficially, in which cases injections of creolin solution and dust¬ 
ing with iodoform are sufficient. The sixth method was suc¬ 
cessful in a few cases, but is generally followed by the appear¬ 
ance of a new swelling further forward on the coronet. I have 
noticed the best results from the seventh method of treatment. 
If the disease should continue or appear again after treating in 
this way, the removal of that portion of the horn and denuding 
affected area will usually be followed by good results. Of 
course, the great objection, especially with troop horses, is the 
length of time that such an operation keeps the animal from 
duty, and often an irregularity of the growth of new horn. 
However, this does not interfere with the usefulness of a troop 
horse. Sometimes a too luxuriant growth of granulation tissue 
occurs, which can be remedied with the scissors and nitric acid 
or other caustic. 
I have yet to hear of a simple effective treatment for this 
class of cases, and will be very grateful to any of my confreres 
who will suggest some routine line of treatment for these bad feet. 
We are fortunate in not being troubled with many diseases 
out here. The native ponies suffer considerably from glanders, 
and we have had a few cases among the public animals. My 
own horse had to be destroyed because of his bad foot becoming 
infected with the bacillus malleus , as was plainly demonstrated 
by its not being amenable to treatment, the general signs of 
farcy, and the appearance of the germ in the discharge from the 
ulcers which occurred upon the leg, and which apparently 
started from the bad foot. 
Specific pan-ophthalmia is common among the native po¬ 
nies, and am sorry to state that a number of animals in our 
regiment have become infected. Will report upon this later 
on. Other troubles among troop horses out here are a few cases 
of founder, colic, heat exhaustion, thrush and broncho-pneumo¬ 
nia, and a miasmatic fever. The general health of the gov¬ 
ernment animals is very good.
