Mr. Manderau, the microscopic examination of the aqueous 
humor of bovines has demonstrated the presence of the 
bacillus of Koch in cases of generalized tuberculosis, as well 
as in those in which only the lungs or the liver were the seat 
of tubercular lesions. 
The process is simple : the animal being kept quiet, and 
the eye rendered insensible by cocaine, the cornea is punc¬ 
tured with a sterilized pipette, which is introduced parallel to 
the axis of the iris, and a sufficient quantity of the humor 
collected for the purpose. The operation is easy to perform, 
and is not usually attended with accidents or complications.

FILARIA OCULI IN A PARROT. 
By G. W. W. 
Early in last May, the attention of the author was called 
to a young grey parrot, the owner of which had for the last 
three months observed a small thread like worm darting 
about in one of its eyes. At first it seemed to give some in¬ 
convenience to the bird, and he frequently rubbed his eye with 
his claw, but latterly he seemed to have become accustomed 
to its presence, and ceased to give it any attention. The 
worm had grown steadily since its first appearance, and at 
the time of examination must have been at least half an inch 
long. The owner having decided not to subject the bird to 
an operation, no treatment was applied. The worm finally 
died, and could afterwards be seen in the bottom of the an¬ 
terior chamber. There was at that time a slight inflammation 
of the iris, manifested by a reddish tinge, and the contents of 
the anterior chamber were not quite so clear as in the normal 
eye. When last observed, three months afterwards, the worm 
was still in the eye, in much the same condition as when 
noticed two or three weeks after its death.— Veterinary Record.
