she had bled considerably during the night. When he 
arrived at the stables, he found the bleeding had stopped, 
one of the servants having applied a quantity of spiders* 
web, and the filly was partaking of some grass. After exa- 
mining the wound, and feeling satisfied that no bad conse- 
quences had arisen from the haemorrhage, he left, but to his 
great surprise, in a couple of days after he received a note 
from the owner, informing him that the filly was becoming 
blind, and requesting his immediate attention to her. 
Upon doing so, and examining her eyes, he found them com- 
pletely amaurotic. This he was at a loss to account for, and 
naturally believed it to have arisen from the weakness caused 
by the secondary haemorrhage. He told the owner that it 
was likely the animal would recover her sight as soon as she 
recovered her usual strength and condition. He therefore 
ordered her to be fed upon nutritious food. As the eyes, 
however, did not appear to get any better, he applied blisters 
behind the ears, but to no purpose, and the animal still re- 
mains blind.. 
Mr. Robinson stated, that in bringing this case before the 
meeting, his object was to elucidate whether Professor 
M‘Call, or any other of the gentlemen present, was of opinion 
that the haemorrhage was the cause of the permanent blind- 
ness or not ; and also whether any case was known in which 
external bleeding had caused paralysis of the optic nerve? 
Professor M‘Catt, in reply, said that any direct pressure 
upon the optic nerves, or their origin, would cause amaurosis, 
but he saw no reason in the case Mr. Robinson had men- 
tioned to connect the haemorrhage with any such pressure ; 
he would therefore attribute the blindness to organic disease 
of the brain, and quite independent of the operation the 
animal had undergone. 
Mr. Steele , of Biggar, said that he had frequently re- 
moved tumours of considerable size, where the animals lost a 
great deal of blood, both during and after the operation, and 
he never saw the least symptom of blindness arising there- 
from ; he was therefore of Professor M c Call*s opinion, that 
organic disease of the brain had existed before the operation, 
although it had not previously developed itself, as otherwise 
the animal must have recovered its sight from the subsequent 
treatment. 
A few remarks from other members followed, but the 
general opinion was, that the blindness was the result of 
organic disease of the brain, and quite independent of the 
bleeding v T hich followed the excision of the tumour. 
The Chairman stated that he was glad Mr. Robin- 
son had brought forward an unsuccessful case, since the
