CLIPPINGS OF PRACTICE.

mains transparent until the death of the animal. This tubercu¬ 
lous ophthalmia, in the four cases observed by the author, took 
place in one eye only, and did not improve under any form of 
treatment. On the contrary, it grew worse with time. After 
death, the iris of the diseased eye is found much thickened. Its 
surface is roughened, and the color of a yellow grey ; incised, it 
shows tuberculous granulations, offering all the changes through 
which these mioplasm pass in other parts of the body. 
Mr. Mathieu says that tuberculous ophthalmia has enabled him 
to diagnosticate phthisis in a cow, though physical signs of the 
chest did not show that there was positively anything abnormal 
in the chest. 
VOMITING IN THE HORSE. 
By Mr. Putzeys. 
Being called to a horse which was taken with vomiting while 
eating grass in an orchard, the author observed that the patient 
presented all the symptoms of vomiting every time he swallowed 
some mouthful of grass, or of any other food. Before passing 
these, a dilatation, varying in size, was easily observed in the infe¬ 
rior part of the sesophagus, and still the most minute exploration 
of the sesophageal organs failed to detect the presence of a foreign 
body. Believing, however, that some body was detained in that 
canal, the probang was used. It very readily passed down into 
the stomach, but no improvement of the animal could be ob¬ 
served. The diagnosis was not given up, however, as it was 
supposed that probably the probang had passed on the side of 
the foreign substance. Remembering that after each ingestion 
of a mouthful of food there was a notable dilatation of the cervical 
portion of the aesopliagus, and attributing it to an accumulation 
of matters in front of the foreign body, the author concluded to 
try the use of these as a tampon. After exciting dilatation of 
the organ by a few mouthfuls of food, he immediately intro¬ 
duced the probang, using it then as a ramrod, and succeeded at 
once in pushing the accumulated mass into the stomach. From 
that moment the vomiting ceased.
