The left eye "of the same horse, with two others, presenting 
analogous alterations. In all three there is strangulation 
and roughness of the sclerotica, the same as is found in 
atrophied eyes. In two of these eyes the optic nerve, after 
having traversed the choroid, resembles, at the point of its 
insertion, a mamelon or papilla. In one case the optic 
nerve sends off a sort of prolongation in the shape of a very 
fine filament to the rest of the retina. In all three of these 
eyes existed a kind of hydrops between the choroid and the 
retina. The cavity containing the liquid is formed by the 
concave surface of the choroid. In one of these eyes this 
cavity contained some yellowish liquid, in the other it was 
brownish, and almost greenish. In each the quantity was 
from fifteen to thirty grammes. The retina and the remains of 
the hyaloid formed the anterior wall of this cavity. The 
ciliary process can be easily distinguished. This anterior 
wall forms at the same time the posterior one of a sac con¬ 
taining the lens and its capsule. This sac, of which the 
anterior parietes are formed by the iris, has its anterior 
surface covered by a pseudo-membrane. The opening of 
the pupil is completely obliterated. There is capsulo-lenti¬ 
cular cataract in all three cases. The capsule is much 
thickened and cartilaginous in all. In one there is an adhe¬ 
rence to the iris. In another there are a number of white, 
chalky points. The crystalline lens is of a dark-yellow 
colour, but reduced in size in one of them, so as to leave 
a cavity between it and the capsule, which is filled with a 
reddish-coloured fluid. In one case the lens has entirely 
disappeared; the capsule is thickened and compressed on 
itself. 
Arid siliceous cataract {carious ).—In this case the capsule 
is still covered with a very thin membrane, which is trans¬ 
parent and brittle, like glass, in fact, analogous to that of 
Descemet, from which it is only separated by the iridian 
diaphragm. In one of these three cases there exists posi¬ 
tively this same envelope of the capsule or double layer of 
the anterior crystalloid. In two cases there is an adhesion of 
the iris and the cornea, without any trace of ulceration. In 
one of these two cases the whitish exudations on the anterior 
surface of the iris have a starry aspect, and present eleva-
