USE OF THE TROCAR AND CANULA IN TYMPANITIS.

which had again accumulated. The rectum was inverted to the 
extent of about five inches, and the animal straining all the time 
to expel the gasses, and also on account of the irritation the salt 
produced, it was impossible to keep the animal on his feet even 
long enough to pass the trocar, so I introduced it while he was 
lying down, about an inch below the first puncture. I got im¬ 
mediate relief. I now gave a drench of hyposulph. of soda, 
which had the effect of neutralizing the gasses so as to give no 
further trouble, the animal going to his usual work in a few days 
without the least trouble from the punctures that were made. 
Case 2. Bay mare about six years old ; property of J . A. 
Thomas, Wooster, was admitted into the infirmary for acute 
indigestion, with symptoms similar to the case just related. 
Punctured her three different times on the right flank with good 
success. This animal had a small abscess form in a week after the 
operation, which I opened and used a carbolic wash, but was 
not taken off work during the treatment of abscess, doing light 
work about town. She made a good recovery. 
Case 3. Bay colt, two years old, property of Mr. Ross, 
farmer, had an attack of indigestion, due to an over-feed of oats 
on the night of April 25th. I was asked to prescribe for the case, 
but not to see it. Prescribed a dose of turpentine and am. carb. 
On the morning of 26th, he was brought to the infirmary in the 
following condition : A debilitated animal, with a pulse of about a 
hundred, weak and indistinct, pupils dilated, abdomen greatly 
distended, breathing laborious, ears drooping, inversion of the 
rectum ; in fact he looked to be in a dying condition. The first 
thing I did was to give relief with the trocar by two punctures 
in the right flank. From the first puncture I got no gas; gave 
stimulants, had him rubbed down well and blanketed, and he began 
to improve for about an hour, when the gasses again began to ac¬ 
cumulate. I tried various kinds of remedies, but failed to get, the 
desired effect, so I again resorted to puncturing, with the desired 
effect. He gradually began to improve, and had no further trouble 
except a small abscess, which I treated the same as case No. 2; 
he made a good recovery. 
Case 4. One of my own driving horses, seventeen years old, 
which I have drived eight years without ever being sick presented
