SPASMODIC ACTION OF THE DIAPHKAGM.

frequently stamping and lifting the hind legs, with frequent at- 
tempts to stale. Blood, and mucus, and urine, continued to pass 
involuntarily for the first few days, but, about the sixth day, the 
dribbling nearly ceased, and the bladder became capable of re- 
taining more urine daily. No untoward symptoms supervened. 
The pulse, in about a week, became natural, and of a healthy 
tone. 
The diet, for the first few days, was a thick mash of bran, 
twice a-day. The medicinal treatment, if you can so call it, con- 
sisted of small draughts of cold water three or four times a-day, 
which T consider the very best of febrifuges; also an occasional 
enema of tepid water. 
This being a very valuable mare, and one which has produced 
many winning colts, Mr. Wreyford has a great wish to get ano- 
ther from her: I see no reason now why he should not. She is 
at grass, getting into good order, and full of spirits. She was 
taken to Stockbridge in the early part of the year, and put to a 
celebrated horse — I think, Camel ; but, was not stinted. She 
was then labouring under the disease, and no doubt that was the 
preventive ; but as the irritability is now got rid of, and both 
the general and local tone restored, I see no reason for her not 
having another foal. 
A CASE OF SPASMODIC ACTION OF THE DIAPHRAGM 
IN A PONY. 
By Air. W. Allison, F.S., Washington. 
On the 24th day of June, I was called to attend a pony, the 
property of a neighbouring gentleman. On examining him, I 
found the following symptoms presenting themselves : — respiration 
regular, but a little hurried, but the same time that I was viewing 
the movements of the respiratory apparatus, I observed another 
peculiar catch or jerk, which the owner had also noticed. The 
pulse was more than 50, regular and soft. It having been bled 
previous to my arrival, as is too often the case in our country, we 
have not so fair an opportunity as we should otherwise have to 
form a true diagnosis of the disease. 
With my finger on the pulse, and my eye on the flank of the 
near side, I observed that the jerk preceded the pulsation a little, 
and each kept quite regular at its respective distance. I placed 
my hand on the, region of the heart, and found nothing abnormal. 
I had little difficulty in concluding that this was spasmodic ac- 
tion of the diaphragm. The pony seemed dull and dejected — 
saliva flowing from the mouth, which was also hot, and the lips
