ABSCESSES IN THE CEREBELLUM OF A HORSE. 253 
In a day or two after the purchase, some swelling in the 
submaxillary space was observed, which gradually increased 
and extended around the angles of the jaw. A seton was 
inserted over it, and kept in for three or four days ; but as it 
did not produce free suppuration, and the swelling continued 
to extend, involving the region of the parotid gland, it was 
removed and poultices applied. Nevertheless the intumes¬ 
cence became still greater, and now causing some difficulty 
of respiration, an incision was made through the lower 
part of the parotid gland, without however reaching the 
abscess; but on the next day, it being carried deeper, a 
large amount of pus escaped. 
From this time the horse appeared to do well, eating 
heartily, and improving rapidly in condition ; while the dis¬ 
charge from the abscess gradual^ diminished. On the 25 th 
he was led out to exercise, when a slight staggering in his 
gait was noticed, but this being attributed to debility did not 
excite much attention. On the following day he was ridden 
by a boy, and appeared to be quite well; but on the morning 
of the 27th, he fell backward in his stall, and could not 
recover himself. With some difficulty he was got up, and 
removed to a loose box, when he appeared to have lost all 
power over the muscles of the left side. 
When I saw him, he was standing, and apparently tranquil; 
the head was turned to the right side, and the pupils were 
dilated ; pulse 48 and full, respiration undisturbed. 
If any attempt were made to move him, he staggered and 
fell against the wall of the box, and an elevation of the head 
produced the same symptoms, while percussion over the 
parietal region caused him to evince acute pain. 
These symptoms, together with the history of the case, led 
me to infer that an abscess had formed in some part of the 
brain, and therefore I gave no hope of the animal’s recovery. 
Nevertheless a blister was applied to the upper part of the 
neck, and some purgative medicine administered ; but in the 
evening he fell, and could not resume his standing position. 
Another practitioner, thinking he could effect a cure, applied 
fomentations over the parotid gland, which were continued 
until midday on the 29th without affording any relief. The 
horse gradually grew worse, and on the afternoon of that day, 
becoming violent and struggling very much, I destroyed him 
by a division of the spinal cord. 
On the removal and examination of the brain, two abscesses 
were found in the cerebellum, separated by a thin central 
layer of brain substance. That on the right side v ? as the 
larger one, and occupied nearly the whole right lobe of the
