TUMOUR IN THE BRAIN OF A HORSE. 
The waggoner who brought the horse informed me that on 
last Tuesday night the animal had been exposed to very wet 
and cold weather, being out at grass. When fetched up on 
the Wednesday morning, he appeared dull, but, nevertheless, 
fed as usual. He worked very dispirited all day, and would 
not turn on the off side. In the evening he was turned out 
to grass again, but instead of feeding as the other horses did, 
he commenced walking round a space of about forty yards* 
diameter, which he continued to do for about a quarter of an 
hour or twenty minutes, always turning to the near side. 
After this he began to feed, and was then left for the night. 
The waggoner went to the field early the next morning, and 
found him with the other horses, still feeding, but as he was 
not wanted that day he remained at grass, nothing further 
being noticed respecting him. 
On Friday morning he was fetched up for work, and while 
feeding he was noticed several times to start back very sud¬ 
denly from the manger, throwing up his head and snorting as 
if frightened. The waggoner, not being able to account for 
this, let him loose, that he might go into the yard, but instead 
of doing this he ran his head against the wall, as if he could 
not see. When taken to the manger again he commenced 
feeding, but occasionally started back. On being harnessed 
for work, the man had some difficulty in putting on the 
bridle, and he observed that while the horse was at plough he 
stumbled very much and did not keep to the furrows. He 
also appeared to be alarmed when spoken sharply to, or when 
touched with the whip. He went on in this way until eleven 
o’clock, wffien the man was wanted among the cows, and the 
horses consequently were unhooked and turned to grass, 
no further notice being taken of this one. When brought 
to the stable on the next morning, and whilst feeding, the 
the same symptoms which had been previously noticed re¬ 
appeared, in consequence of which it was decided that he 
should be sent to me. 
On examination, I found that the least noise caused him 
very great excitement. He could not stand still, nor would 
he walk into the stable. The pulse was 70 in number, and 
although strong and firm to the feel, was slightly intermittent. 
The mucous membranes were unaffected. 
From these symptoms, together with the waggoner’s report, 
I concluded that the animal was suffering from brain disease, 
and that it was probably associated with some inflammatory 
action. Acting upon this opinion, I bled him copiously, ex¬ 
tracting about ten quarts. The blood was at first very dark 
in colour, but nevertheless it flowed freely. The bleeding
