several places, thus holding it fast. When the sole was re¬ 
moved, the animal soon again did well. 
I was requested to see a horse, reported to have a large 
and dangerous swelling on his neck, which extended to the 
front of his chest and along the bellv. 
I soon found it was owing to the existence of the larva of 
one of the GEstri, which had been deposited in the cellular 
tissue of the neck, under the mane. The parasite seemed 
ready to emerge, but the dry scab resisted its escape for 
several days. When pressed round the edge, the larva was 
forced out, and with it much purulent matter. A free use 
of fomentations, with the exhibition of a laxative, was all 
that was required, to the great satisfaction of the owner 
of the animal, who was afraid his horse had contracted 
a formidable malady. 
LITHOTOMY IN THE HORSE. 
By D. Sayer, M.R.C.V.S., Norwich. 
The horse operated upon by me was the property of H. 
Ling, Esq., of this city. He was about seven years old, 
fifteen hands high, strongly built, a good hack, hunter, and 
harness horse, and had been in the above gentleman's pos¬ 
session a short time only. 
Soon after purchase the animal presented symptoms of 
e: something being wrong" in the urinary organs. He fre¬ 
quently attempted to stale, and the act was accompanied 
with great difficulty, the urine being voided in small quan¬ 
tities only, and sometimes tinged with blood. He was ad¬ 
mitted into my infirmary on the 28th of February, 1859, 
presenting symptoms of the existence of calculus in the 
bladder; and a short time after his admission, on a careful 
examination being made, my suspicions were confirmed. 
The tests suggested by Professor Spooner, both chemical 
and microscopical, being applied, fully proved the presence 
of carbonate of lime in the urine. I at once communicated 
my opinion to the owner of the existence of a calculus, and 
advised an operation for its removal. This was immediately 
concurred in by him, but the animal not being in a fit con¬ 
dition to be operated upon, a postponement was deemed 
advisable. Proper measures being adopted for that pur¬ 
pose, he was thought fit for the operation on March 14th.
