change of climate and a run at grass, and an alterative treat¬ 
ment medicinally. But as the colt had cost him nothing, if 
he was willing to pay for the feed till it either recovered or 
died, I would like to experiment with the case, as I had an 
idea that bighead was a sort of cancerous condition, and if 
we could get at the part first affected, and use some effective 
caustic, we might cure the disease. 
Two days after he brought me the colt, and told me to go 
ahead and do what I liked with him, and if he died it was his 
loss. Working on this basis, and finding the following con¬ 
dition to exist, I treated as follows : 
The colt, a two-year-old t horoughbred, whose pedigree I 
have forgotten, was a bay about fifteen hands high, and a 
stallion. He could hardly breathe from the enlargement of 
the nasal and superior maxillary bones, and the greatly con¬ 
gested condition of the nasal mucous membrane, and there 
was a rusty-looking discharge from both ‘nostrils, though the 
quantity was not of any moment, simply a little trickling; as 
to his further condition as regards body and extremities, out¬ 
side of the fact that in this case there existed extreme emacia¬ 
tion, the symptoms were identical with those in Williams’ 
Surgery, except that the only enlargement discernible was 
that existing in the face, and which will be exactly illustrated 
to you by a reference to Fig. 31, in the above mentioned work, 
had the colt died and the head been dissected. 
We now took the animal and after thoroughly washing 
the face over the affected part with a bi-chloride of mercury 
solution, inserted a seton over the enlargement on each side 
from the lowest point of the enlargement to directly below 
the eye, where we brought it out; on the setons we smeared 
a small quantity of the bin iodide of mercury blister as usually 
given, one in eight. 
This we allowed to remain for twenty-four hours, after 
which we removed the setons, and replaced them with new 
tapes after thoroughly cleansing with an antiseptic solution ; 
these new tapes we moved every day for four days, taking 
care to keep the wound clean and free from accumulations, 
and then for two weeks, each day after dressing, we dusted
