INVERSION OF THE BLADDER IN A SOW. 
old, belonging to Mr. Joseph Nash, ofReigate, which he believed 
to have some affection of the head, as it seemed, even from its 
birth, totally unconscious of its near approach to any object, 
although he considered it to have good eyes. 
On entering the stable, I found the foal apparently healthy ; 
but when excited to motion, it blundered against any source of 
obstruction which might be in its way ; running its head against 
the wall or the mare's legs, in such a way as to convince me that it 
was totally blind. On examining the pupil of each eye, it was 
greatly dilated and motionless—the humours of the eye were 
clear, and of a blueish tint. The cornea and sclerotic tunic had 
a healthy appearance. There were no adhesions of the iris, no 
symptom of cataract, nor any undue vascular action. After a 
few days, being convinced that the foal would never have sight, 
and being a nag foal, I ordered him to be destroyed, and 
sought, in a post-mortem examination, the cause of this unusual 
event. 
The substance of the brain appeared healthy throughout. 
The ventricles contained no more than a proper and natural 
quantity of fluid. Above the tubercula quadrigemina there was a 
small mass of the size and shape of a lentil, free and unattached. 
On tracing the optic nerve in its passage from the base of the 
brain, it was found in a complete state of atrophy, there being 
hardly any nervous substance within the neurilema. It presented 
a remarkable contrast to the several branches of the fifth, which 
were of their usual size and condition. It is to be regretted that 
this most important organ, the eye of the horse, affecting both 
his usefulness and value so materially, should so frequently 
be the subject of disease over which our curative means avail so 
little. 
INVERSION OF THE BLADDER IN A SOW. 
Bj/ Mr. Edmund Neale, 0/ Burbage. 
On the 21st of last February a sow, belonging to Mr. Joseph 
Eagle, of Burbage, littered in the morning, and brought ten pigs, 
apparently without any difficulty ; but, immediately afterwards, 
something came out (to use the owner’s own words) exactly 
resembling the bladder, and which appeared to be about half full. 
Finding that it did not come away, he became alarmed, and 
sent for a pig butcher, who said it was the womb, and that it 
must be put back ; he accordingly put it back, or attempted to
