that the poor animal stoutly resisted our efforts to remove the 
cause of its suffering. This, however, was soon done, and 
the parts being cleaned with tepid water, were afterwards 
dressed with Tinct. Myrrhae. The relief afforded was so 
immediate that the pony eagerly partook of some water 
which was close at hand, and would have drank a far greater 
quantity than would have been desirable, had it been per- 
mitted. Little after-treatment was necessary, beyond the 
daily application of the tincture, a mash diet, and the sub- 
stitution of oatmeal gruel for plain water] . 
CYSTIC CALCULUS IN A HORSE. 
OPERATION. DEATH. 
By Thomas Aubrey, M.R.C.Y.S., Salisbury. 
I was requested, December 15th, 1854, by E. P. Squarey, 
Esq., of Odstock, to see a thorough-bred horse, eight years 
old, sixteen hands high, which he described as having been 
suffering from a stone either in the kidney or the bladder for 
three years past. 
He informed me that in June, 1852, the horse, being then 
five years old, and in excellent health and condition, had a 
“ summer’s run” given him, it being intended to prepare him 
for the next hunting season. He remained in the straw-yard 
feeding on vetches, &c., up to August, when he was taken 
into the stable, to be conditioned. The owner soon afterwards 
rode him, but he had not proceeded far before he suddenly 
stopped, and staled almost pure blood. The symptoms of 
deranged health continued to gradually increase, till the 
animal was reduced to a mere skeleton. Notwithstanding 
this, he was regularly driven up to Christmas last. 
The leading symptoms indicated great irritation of the uri- 
nary organs. The animal was frequently staling ; the urine 
being sometimes mixed with blood. After passing all he 
could, he would stand in the same position for several 
minutes, and strain violently. The penis was often pendu- 
lous, and occasionally the urine would escape involuntarily. 
Having carefully examined the bladder, per rectum, I was 
satisfied of the existence of a very large calculus within 
that organ, and I at once communicated my opinion to the 
proprietor, stating that no treatment would be of any avail 
excepting the operation of lithotomy, and that this would be 
attended with considerable danger, from the great size of the
