tlie primary cause of illness, interfering with the circulation. The 
long journey the cause that produced death, the vessels becoming 
,congested, and ultimately throwing out serum. It is remarkable 
that she always turned the same way in the loose box as she had 
been accustomed to do in the mowing machine. Could it have 
been correctly diagnosed, a puncture might have been made through 
the bone. 
Mr. Tom Taylor also related a very interesting case, which 
occurred in his practice about a month previously, and illustrated 
it by a most beautiful and perfect specimen.— Subject: A light spring 
cart-mare, about seven years old; Mr. Taylor had known her about 
eighteen months, during which time she had been healthy, with the 
exception of one or two attacks of influenza. Symptoms resembled 
sleepy staggers; she was dull and heavy, pulse 32, and constantly 
boring her head into a corner and resting against the manger. 
Administered physic, &c. The symptoms gradually developed 
themselves into those of madness; she would keep her head obsti¬ 
nately in a corner for ten minutes at a time, and shiver all over, 
with her mouth awry and her eyes amaurotic. Attempted to bleed 
her, and after had opened the vein she became so unmanageable that 
for some time could not get near her to pin it up, until her head 
was forcibly pulled through a window. She then had cold water 
applied to her head by means of a pipe, and mustard to her stomach; 
carbonate of soda with acetate of potash were given. The 
following day she was much better, and the physic had acted 
well; she continued improving about four days, and worked well 
for about ten days, when the attack returned, but yielded to treat¬ 
ment in another four or five days. She had five such fits, each 
worse than the other; while she was in the last fit I took Mr. Gibson 
to see her, but found her dead. The post-mortem revealed a healthy 
condition of the thoracic and abdominal organs, with the excep¬ 
tion of the stomach, which was slightly inflamed. The brain was 
taken from its cavity, base uppermost, and thus was brought in 
view without injuring it, a very large sac, formed by a fine delicate 
membrane enveloping a quantity of serum. The sac had caused 
absorption of a large portion of the anterior part of the medulla 
oblongata and of both hemispheres, its only attachment being by 
a small twine-like connection to the interior of the right hemi¬ 
sphere, the pineal gland being directly underneath tbe body of 
the tumour. Mr. Taylor, for the information of the members, 
brought the brain with him, and it certainly was a beautiful 
specimen, and was examined by all present with great interest. 
A spirited discussion followed the relation of these cases. 
Mr. Lawson said he had seen several cases with similar symptoms 
as those described, but, as they liad all recovered and passed out of 
his sight, he was not able to trace them to their several causes. He 
had one horse of his own that was liable to such attacks very 
suddenly, and they as quickly passed ofi'. He was also sold, and he 
did not know the close of his career. He thought the best treat¬ 
ment for such cases was getting the bowels to operate freely, and
