certain the animal has had inflammation in that
portion of the eye ; but should the centre part of the
cornea be perfectly transparent, and yet the margin of
it where it unites with the sclerotica have a hazy ring,
it may be concluded that this has been occasioned by
recent inflammation, and consequently the eye is pre-
disposed to a return of it. During the operation of
thus inspecting the eye, mind that no white or pale-
coloured object be near, as its form and great trans-
parency are very likely to reflect these rays, and
deceive the person making the examination. Atten-
tion to the dilation and contraction of the pupil will
materially aid a person in the detection of blindness
or otherwise. When the cornea and crystalline lens
are quite transparent, with the retina paralysed and of
course not liable to be affected with the light, it is
extremely difficult to detect blindness either in one or
both eyes. It generally happens that when a horse is
totally blind, * he has a constant and rapid motion
with its ears, it also lifts its feet high as if some
obstacle presented itself, and puts its feet down
with cautious uncertainty. Do not forget to pay
particular attention to the pupil of both eyes, and
notice if they are both of a size while it is in the stable,
and as it approaches the door observe whether both
pupils contract equally as tbey are subjected to a
stronger light. If, however, the horse is in a fair or at a
distance from a stable, place the crown of a black hat
over the eye, and then observe after it has obscured it
from the light for a little while whether the pupils con-
tract. Repeat the experiment on both eyes, and you will
