also contains the two layers of the cristalloid, and adheres to 
the posterior surface of the iris. As long as the lens still 
exists its anterior capsule is often attached to the iris by a 
pseudo-membranous exudation, which may increase to the 
formation of false membranes obliterating the pupil. The 
atrophy of the globe of the eye (‘ Iconographie/ p. 427) is 
an ordinary consequence of the violence of the ophthalmia. 
It more frequently takes place after the other anatomical alte¬ 
rations than after simple cataract, with which, however, it 
mav coexist.

4th. Nothing of this takes place in glaucoma. The cap- 
sulary or pseudo-membranous cataract, the synechiae poste¬ 
rior, the small pseudo-membranous bands or false membranes 
of the pupil, the detachment of the retina, the absorption of 
the vitreous humour and the lens, all these are absent in 
glaucoma, or if they exist are merely accidental. Atrophy 
likewise rarely supervenes in glaucoma, while it is one of the 
ordinary terminations of specific ophthalmia; principally, how¬ 
ever, when its march is rapid and the attack acute. 
5th. These conclusions, deduced from the observations 
annexed, and which have been selected from a large number, 
may appear somewhat arbitrary. Other observations and 
other dissections may perhaps partly invalidate them. It "was, 
however, necessary to put them into shape, so as not to leave 
my work too much without data and apparent usefulness. I 
have added at the end of these sheets “ On Cataract and its 
Operation in the Horse ” a few words deduced from the same 
dissections. At all events, I must beg the reader to excuse 
all errors in this narrative which might have escaped me, 
owing to the very short space of time I have been obliged to 
collect, revise, and copy rough notes made off-hand during 
dissection, as well as hastily to add the reasons for their 
introduction, so as not to cause the publication of these 
documents to be again postponed after more than twenty 
vears.

6th. Taking my stand on the anatomical grounds which I 
have tried to establish in the preceding pages, I cannot consider 
as founded on true theory the application of iridectomy to spe¬ 
cific ophthalmia in the horse. In glaucoma this operation is 
destined to remove the intra-ocular pressure. There exists 
neither the exudative phlegmasy of the membrane of Descemet, 
nor acute iritis nor sub-retinal effusion. The contrary to this 
takes place in specific ophthalmia. An incision into the cornea, 
such as might be made with the lanceolar knife, and the exci¬ 
sion of a considerable portion of the iris, might cause serious 
inflammatory accidents, and tend to more violent exudations
