are at their service ; but through the length of time and the im¬ 
possibility in which I have often been placed of replenishing 
the alcohol, I cannot answer for their perfect preservation. 
2nd. I must acknowledge that the result of my anatomical 
researches is not favorable to the hypothesis of the analogy 
existing between the pathology which constitutes glaucoma 
and that which takes place during and after an attack of 
specific ophthalmia. In the latter, irido-choroiditis certainly 
exists; but it follow’s a course and its termination is quite 
different from that of glaucoma, it being understood to apply 
only to those cases of specific ophthalmia which terminate in 
blindness; these being the only ones that can be compared 
with it. 
3rd. That which more clearly distinguishes specific oph¬ 
thalmia from glaucoma may be anatomically summed up 
thus—the cornea may become inflamed and ulcerated, but 
more frequently the membrane of the aqueous humour 
(membrane de Descemet ), consequent on this phlegmasy, so rare 
in the human subject, but almost constant in specific oph¬ 
thalmia in the horse. This membrane becomes opaque, either 
in striae or in layers, and it is shrivelled. Plastic exudations are 
deposited between it and the iris. This last membrane forms 
adhesions with the cristalloid anterior, which also becomes 
opaque, striated, or in layers, resulting from the fibro-albu- 
minous exudation on the posterior surface of the iris. The 
lens also becomes opaque. The cristalloid is often the seat 
of striated, chalky opacity, and may become corrugated. The 
lens, from several of my observations, may likewise become 
softened, liquified, and disappear altogether; and this occurs 
almost always under the influence of pressure from a liquid 
which is secreted between the choroid and the retina (hydrojpisie 
sous cJioro'idienne sereuse et sangu-inolente— e Iconographie Oph- 
thalmologique, 5 p. 498). This loosens the retina and forces it 
towards the centre, and when thus loosened it forms a sort of 
cone, the base of which is anterior and the apex posterior. 
The apex, under the incessant pressure of the fluid effused, 
is ultimately torn from the papillae of the optic nerve, where 
there remains now only a simple vestige or a papilliform 
mamelon, or else a thin, cylindrical cord, either short or elon¬ 
gated. The anterior portion of the cone is more and more 
pushed forward after the rupture of its apex, and becomes 
by degrees more rounded and flattened, and afterwards forms 
itself into an adventitious body, surrounded with a false mem¬ 
brane, generally adhering to the crystalloid posterior, and 
containing the debris of the hyloid ( Obs . 2 and others). 
In case of the absorption of the lens, this false membrane
