MISCELLANEOUS CASES. • 235 
Rupture of the pleural Covering of the Lungs. 
I was sent for to examine a blood mare, that had died on the 
previous day. I found all the abdominal viscera healthy, and 
the right side of the lungs ; but on the left side of the thorax 
there was a large quantity of blood, proceeding from a rupture 
of one of the lobes. There was an opening through the pleural 
covering, and into the parenchymatous substance, large enough 
for me to introduce two of my fingers. 
One of the grooms had taken this mare from grass, a journey 
of twelve miles. He was seen riding her up a hill, at the top of 
her speed. He had not proceeded more than nine miles before 
she dropped and died. 
Haemorrhage from the Uterus. 
There was a false presentation of a foetus from the vagina of a 
cow. One hind leg protruded. The other leg was raised, and 
the calf brought away. The operator, although very expert in 
these matters, must have injured the uterus in raising the leg, 
for profuse bleeding from the uterus immediately followed, and 
proceeded almost to syncope. The farmer talked of destroying 
the animal, but experience suggested the proper remedy. A 
considerable quantity of the black oil, as directed to be made by 
Mr. Morton in his Pharmacopoeia, was introduced into the uterus 
by means of a sponge, and the bleeding was speedily arrested. 
A drink was then given, composed of Epsom salts, opium, digi- 
talis, nitre, and a small portion of caraway powder, in tepid 
water. She got well without any further treatment, only the 
skin became very yellow, and the hair came off* in patches. 
Tenesmus, and Voiding of Blood. 
A few months ago I was sent for, late at night, to a mare, ap- 
parently in a dying state. She was lying down and getting up 
continually — the membranes of the mouth, nose, and eyes were 
exceedingly pale — the pulse 100, and scarcely detectable at the 
jaw — she was bedewed all over with a cold perspiration — there 
were violent tremors, and every symptom of approaching death. 
She voided from the anus great quantities of a bloody fluid, and 
there was almost constant tenesmus. 
I administered, every hour, half an ounce of spirit of nitrous 
mther, and the same quantity of tincture of opium, and a drachm 
of sulphuric acid largely diluted with water. 
In a short time she began to amend. On the following morn- 
ing she ate a little. I then gave her a laxative, and in a few days 
she was well. She had been on a journey of ten miles with a 
load of straw ; and, on her way back, about eight miles from 
home, the bloody purging began to appear.
