its head pressed against some firm object and unmindful of any¬ 
thing going on about him. The most common form of cerebral 
inflammation is due to some dietetic error causing a sympathetic 
affection ; this form may be distinguished from cerebral disease 
from other causes by one symptom in particular, that is the 
normal, or even subnormal, temperature, for in the formei there 
is a rise in temperature. 
Two cases which came under my observation will illustrate 
meningitis and sympathetic cerebritis. 
The first, a case of acute meningitis, was in a black gelding 
which I saw about seven o’clock in the evening. I was told that 
in the early afternoon he had been taken away to be clipped and 
being a nervous animal, had caused them some trouble, and in 
endeavoring to punish him had struck him with something, and 
had placed upon his head some kind of a controlling bridle and 
had thrown him down. 
When I arrived he was in a stage of great excitement, so 
much so that they warned me about going into the stall, which was 
roomy box, saying that he was crazy and would jump on me. 
I finally got up to him and put my hand on him ; found his 
head very warm, pulse quick, eyes staring and bloodshot, with 
pupils contracted owing to his great anaesthesia. I was unable 
to take his temperature. There was much pain about the head, 
his appetite was very good, however, and continued so through¬ 
out his sickness. 
In a few days this delirium changed to the comatose condi¬ 
tion, and the animal stood in a corner unmindful of anything. 
This, however, gradually wore away, and the animal made a 
good recovery. 
Case number two ; instance of sympathetic ceiebral distur¬ 
bance was in a bay mare which had been working constantly on 
a farm; had been fed meal in large quantities for a few days and 
suddenly refused to eat and drink, and soon began to bore her 
head against the wall; eyes dull and indifferent to everything, 
except occasionally she would thrash her head, thus wounding 
it greatly and then remain quiet again.
