A CASE OF SEVERE CHRONIC FOOT LAMENESS. 
By Mr. G. M. Marshall, V.S., York. 
Sept. \^th, 1837.—I WAS this day requested by Mr. Simpson, of 
the York Hotel, to examine a chestnut horse, nine years old, that 
he had purchased at a sale of cast troopers for a very trifling sum, 
he being very lame in the near hind foot. 
On examining him, there was an enlargement over the coronet, 
on the outside, with a small ulcer on the top of it, which at first 
sight appeared to be a sinus, but, on attempting to probe it, I found it 
not to be one. There was a sinus at the posterior part of the heel, 
over the frog, which was about two inches in depth, taking a direc¬ 
tion downward and forward; and the sole was very much elevated, 
with scarcely the vestige of a frog. He went on his toe, being 
totally unable to put the heel to the ground. The under part of the 
foot was covered with astringent powder. 
On inquiring into the history of this case, I was informed that, 
shortly after joining the regiment, about five years since, he re¬ 
ceived an injury, caused by the point of a file entering at the side 
of the frog, and making its appearance over the lateral cartilages 
on the outside. By the remedies then used he became nearly 
sound, so as to do light duty, but was frequently lame, and, latterly, 
altogether off duty. 
I commenced the treatment by trimming the sole, and lowering 
the wall of the hoof all round, ordering poultices to be kept con¬ 
stantly applied, which were continued without any other treatment 
to the 25th, the enlargement over the coronet remaining very hard. 
26th .—Syringe the sinus at the back of the heel with a sol. 
chlor. calcis, and continue poultice. 
26th to the 2Sth .—Same treatment. 
2^th. —Syringe, with sol. sulph. zinci, and continue cataplasm. 
Oct. 6th .—Same treatment continued: the enlargement over 
the coronet has suppurated, and there is a sinus formed, which 
communicates with the one at the back of the heel; there is also a 
hollow place near the point of the frog, which I opened, and I fan¬ 
cied I felt a loose portion of bone, but which I could not then 
extract. I thinned the sole, and lowered the crust as much as it 
would admit of all round; applied a shoe with a lever at the toe, 
to force him to put his heel gradually to the ground. Syringe 
with sol. sulph. zinc., and dress the frog with petrolium comp., 
applying firm pressure to it. 
\2th .—Same treatment has been continued to the present time.
