The mare, the property of Lord Melville, was discovered early 
one morning with half the anterior part of the lower jaw hanging 
pendulous. No cause for the fracture could be assigned. The 
halter with which she had been secured was found broken. The 
fractured portion of the jaw was placed in its proper position and 
secured there by means of copper wire, and all went on well for 
four weeks. At the expiration of that time, on a Tuesday morn¬ 
ing, epistaxis was observed, which was arrested by the application 
of cold water to the head, and before night she appeared quite lively 
and ate satisfactorily. On the following morning she exhibited 
symptoms of cerebral disturbance by walking in an unsteady 
manner, with the head turned to the right side, in a continuous 
circle, in her box. The pupils were dilated, and she stood 
(except when perambulating the box) with her forelegs wide 
apart like props, trying to preserve her equilibrium, and endea¬ 
vouring to bring her head against the wall to obtain pressure on 
the occipital region. As she was an old mare no treatment was 
had recourse to, and she was destroyed. 
Post-mortem Examination of Head.—“ At the request of Mr. 
Aitkin,” said Professor Walley, “I undertook this duty. I 
found all parts of the brain perfectly normal until I raised the 
cerebellum and divided its connection with the medulla ob¬ 
longata, when I discovered, posteriorly to the valve of Yieussons, 
and stretching transversely over the whole width of the cerebellum, 
a new vascular growth, nodulated on its free surface, and from 
two to two and a half inches long, three quarters of an inch wide, 
and about one sixth of an inch in its deepest portion. This 
growth was, in my opinion, the result of injury to the plexus of 
blood-vessels on the inferior surface of the cerebellum, received 
by contre-coup at the time of the accident, and, if I may so express 
myself, consisted of healthy or exuberant granulations, which did 
not interfere with the functions of the brain until they became so 
large as to produce pressure on the cerebellum and medulla ob¬ 
longata, giving rise to the symptoms observed. If any serum 
from effusion existed in the fourth ventricle it had escaped 
through the foramen magnum when the animal’s head was 
removed from its body.” 
Professor Walley next exhibited part of the vagina and uterus 
of a heifer, in which the peculiar “ twist ” of the neck of the 
uterus occasionally met with was very distinctly shown. The 
Professor stated that the case occurred in the practice of Mr. 
Brown, West Calder, from whom he had not as yet received 
particulars, but he believed that the heifer, being quite unable to 
calve, had been destroyed. He was not aware that turning the 
animal over and over with a view to unravel the te twist” had 
been had recourse to, but even had it been successful parturition
